Background and Basis of Presentation [Abstract]
Background and Basis of Presentation	NOTE 1 – BACKGROUND AND BASIS OF PRESENTATION  Business Operations : MRC Global Inc. is a holding company headquartered in Houston, Texas. Our wholly owned subsidiaries are global distributors of pipe, valves, fittings (“PVF”) and related products and services across each of the upstream (exploration, production and extraction of underground oil and gas), midstream (gathering and transmission of oil and gas, gas utilities, and the storage and distribution of oil and gas) and downstream (crude oil refining and petrochemical and chemical processing and general industrials ) sectors. We have branches in principal industrial, hydrocarbon producing and refining areas throughout the United States, Canada, Europe, Asia , Australasia , the Middle East and Caspian . Our products are obtained from a broad range of suppliers.  Basis of Presentation : We have prepared our unaudited condensed consolidated financial statements in accordance with Rule 10-01 of Regulation S-X for interim financial statements. These statements do not include all information and footnotes that generally accepted accounting principles require for complete annual financial statements. However, the information in these statements reflects all normal recurring adjustments which are, in our opinion, necessary for a fair presentation of the results for the interim periods. The results of operations for the three months ended March 31, 2018 are not necessarily indicative of the results that will be realized for the fiscal year ending December 31, 2018 . We have derived our condensed consolidated balance sheet as of December 31, 2017 from the audited consolidated financial statements for the year ended December 31, 2017 . You should read these condensed consolidated financial statements in conjunction with the audited consolidated financial statements and notes thereto for the year ended December 31, 2017 .  The consolidated financial statements include the accounts of MRC Global Inc. and its wholly owned and majority owned subsidiaries (collectively referred to as the “Company” or by such terms as “we,” “our” or “us”). All material intercompany balances and transactions have been eliminated in consolidation.  Recent Accounting Pronouncements : In February 2016, the Financial Acco unting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, Leases, which will replace the existi ng guidance in ASC 870, Leases. This ASU requires a dual approach for lessee accounting under which a lessee would account for leases as finance leases or operating leases. Both finance leases and operating leases will result in the lessee recognizing a right-of-use asset and a corresponding lease liability. For finance leases, the lessee would recognize interest expense and amortization of the right-of-use asset, and for operating leases, the lessee would recognize a straight-line total lease expense. This guidance is effective for annual and interim reporting periods of public entities beginning after December 15, 2018. We are in the process of evaluating the effect of the adoption of ASU 2016-02 on our consolidated financial statements. Adoption of New Accounting Standards : ASU 2014-09, Revenue - Revenue from Contracts with Customers . On January 1, 2018, we adopted accounting standard ASC 606, Revenue from Contracts with Customers (“new revenue standard”) using the modified retrospective method. Under this method, a cumulative effect of initially applying the new revenue standard requires an adjustment to the opening balance of retained earnings, and the comparative information continues to be reported under the accounting standards in effect for those periods prior to adoption . The cumulative effect of initially applying the new standard was immaterial to our consolidated financial statements. Under the new revenue standard, revenue is recognized when control of the promised goods or services is transferred to our customers in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Substantially all of our revenue is recognized when products are shipped or delivered to our customers, and payment is due from our customers at the time of billing with a majority of our customers having 30 day terms. Returns are estimated and recorded as a reduction of revenue. A mounts received in advance of shipment are deferred and recognized when the performance obligations are satisfied . Sales taxes collected from customers and remitted to governmental authorities are accounted for on a net basis and , therefore , are excluded from sales in the accompanying consolidated statements of operations. Cost of sales includes the cost of inventory sold and related items, such as vendor rebates, inventory allowances and reserves, and shipping and handling costs associated with inbound and outbound freight, as well as depreciation and amortization and amortization of intangible assets. In some cases, particularly with third party pipe shipments, shipping and handling costs are considered separate performance obligations, and as such, the revenue and cost of sales are recorded when the performance obligation is fulfilled.  Our contracts with customers ordinarily involve performance obligations that are one year or less. Therefore, we applied the standard’s optional exemption that permits the omission of information about our unfulfilled performance obligation s as of the balance sheet dates . ASU 2017-12 , Accounting for Derivatives and Hedging Transactions (Topic 815) Targeted Improvements to Accounting for Hedging Activities . In March 2018, we early adopted ASU 2017-12. The new standard amends the hedge accounting model to better portray an organization’s risk management activities in the financial statements, as well as simplifies the applications of certain hedge accounting guidance. The implementation of ASU 2017-12 did not have a material impact on our consolidated financial statements.

Contract Balances

Contract Balances [Abstract]
Contract Balances	NOTE 2 – CONTRACT BALANCES  Contract Balances : Variations in the timing of revenue recognition, invoicing and receipt of cash result in categories of assets and liabilities that include invoiced accounts receivable , uninvoiced accounts receivable , contract assets, and customer advances (contract liabilities) on the consolidated balance sheet s . Generally, revenue recognition and invoicing occur simultaneous ly as we fulfill our performance obligations resulting in contract assets. Payment is typically due from our customers within 30 days of invoicing . We consider contract assets to be accounts receivable when only the passage of time is required before payment is due. In certain cases, particularly those involving customer-specific documentation requirements, receipt of payment is not assured unless and until we meet the documentation requirements . In these cases, we recognize a contract asset separate from accounts receivable until those requirements are met, and we are able to invoice the customer. Further, we sometimes receive advances or deposits from our customers before revenue is recognized, resulting in contract liabilities, or deferred revenue.  Contract Assets : We record contract assets , including accounts receivable, when control of the promised goods or services is transferred to our customers . In situations where we have uninvoiced contract assets due to customer-specific documentation requirements, as discussed above, we recognize these amounts distinct from accounts receivable. Our contract asset balance associated with these requirements, as of March 31, 2018 and December 31, 2017 , was $34 million and $31 m illion, respectively. These contract asset balances are included within accounts receivable in the accompanying consolidated balance sheets.  Contract Liabilities : We record deferred revenue when cash payments are received in advance of our performance, including amounts which are refundable. The deferred revenue balance at March 31, 2018 and December 31, 2017 was $32 million and $30 million, respectively. Deferred revenue balances are included within accrued expenses and other current liabilities in the accompanying consolidated balance sheets.

Long-Term Debt	 NOTE 4 – LONG-TERM DEBT The components of our long-term debt are as follows (in millions ):    March 31, December 31,  2018 2017  Senior Secured Term Loan B, net of discount and issuance costs of $3 $ 396 $ 397  Global ABL Facility 243 129  639 526  Less: current portion 4 4  $ 635 $ 522 Senior Secured Term Loan B : In September 2017, the Company entered into a Refinancing Amendment and Successor Administrative Agent Agre ement relating to the Term Loan Credit Agreement, dat ed as of November 9, 2012 , by and among the Company, MRC Global (US) Inc., as the borrower, the other subsidiaries of the Company from time to time party thereto as guarantors, the several lenders from time to time party thereto, Bank of America, N.A., as administrative agent, and U.S. Bank National Association, as collateral trustee. Pursuant to the amendment, the parties agreed to appoint JPMorgan Chase Bank, N.A. as the new administrative agent for the lenders. As amended, the Term Loan Credit Agreement provides for a $400 milli on seven -year Term Loan B (the “Term Loan”) which matures in September 2024 . The Term Loan allows for incremental increases in facility size by up to an aggregate of $200 million, plus an additional amount such that the Company’s first lien leverage ratio (as defined under the Term Loan) would not exceed 4.0 0 to 1.00 . MRC Global (US) Inc. is the borrower under this facility, which is guaranteed by MRC Global Inc. as well as all of its wholly owned U.S. subsidiaries. In addition, it is secured by a second lien on the assets securing our Global ABL Facility , defined below, (which includes accounts receivable, inventory and related assets) and a first lien on substantially all of the other assets of MRC Global Inc. and those of its U.S. subsidiaries, as well as a pledge of all of the capital stock of our domestic subsidiaries and 65 % of the capital stock of first tier, non-U.S. subsidiaries. We are required to repay the Term Loan with certain asset sales and insurance proceeds, certain debt proceeds and 50% of excess cash flow , as defined in the Term Loan, (reducing to 25% if our first lien leverage ratio is no more than 2.75 to 1.00 and 0% if our first lien leverage ratio is no more than 2.50 to 1.00). In addition, the Term Loan contains a number of customary restrictive covenants. Interest Rate Swap : We enter into interest rate swaps to manage the interest rate risk associated with our floating-rate LIBOR-based Term Loan. In March 2018, we entered into a five -year interest rate swap that became effective on March 31, 2018, with a notional amount of $250 million from which the Company will receive payments at 1-month LIBOR and make monthly payments at a fixed rate of 2.7145% with settlement and reset dates on or near the last business day of each month until maturity. The fair value of the swap at inception was zero . We have designated the interest rate swap as an effective cash flow hedge utilizing the guidance under ASU 2017-12. As such, the valuation of the interest rate swap is recorded as an asset or liability, and the gain or loss on the derivative is recorded as a component of other comprehensive income. The fair value of our interest rate swap is estimated based on the present value of the difference between expected cash flows calculated at the contracted interest rates and the expected cash flows at current market interest rates. We recognize interest rate swaps on the accompanying balance sheet at fair value using observable inputs. We recorded a liability of $1 million at March 31, 2018. Global ABL Facility : In September 2017, the Company entered into a Third Amended and Restated Loan, Security and Guarantee Agreement (the “ Global ABL Facility ”) by and among the Company, the subsidiaries of the Company from time to time party thereto as borrowers and guarantors, the several lenders from time to time party thereto and Bank of America, N.A. as administrative agent, security trustee and collateral agent. As part of the amendment, the multi-currency global asset-based revolving credit facility was re-sized to $800 million from $1.05 billion and the maturity was extended to September 2022 from July 2019 . This facility is comprised of $675 million in revolver commitments in the United St ates, $65 mil lion in Canada, $18 million in Norway, $15 million in Australia, $13 million in the Netherlands, $7 million in the United Kingdom and $7 million in Belgium. It contains an accordion feature that allows us to increase the principal amount of the facility by up to $200 million, subject to securing additional lender commitments. MRC Global Inc. and each of its current and future wholly owned material U.S. subsidiaries guarantee the obligations of our borrower subsidiaries under the Global ABL Facility. Additionally, each of our non-U.S. borrower subsidiaries guarantees the obligations of our other non-U.S. borrower subsidiaries under the Global ABL Facility. Outstanding obligations are generally secured by a first priority security interest in accounts receivable, inventory and related assets. Excess Availability, as defined under our Global ABL Facility, was $409 million as of March 31, 2018 .  Interest on Borrowings : The interest rates on our borrowings outstanding at March 31, 2018 and December 31, 2017, including the interest rate swap and amortization of debt issuance costs, were as follows:    March 31, December 31,  2018 2017  Senior Secured Term Loan B 6.02% 5.18%  Global ABL Facility 3.74% 3.19%  Weighted average interest rate 5.15% 4.69%

Income Taxes [Abstract]
Income Taxes	NOTE 5 – INCOME TAXES  For interim periods, our income tax expense is computed based upon our estimated annual effective tax rate and any discrete items that impact the interim periods. Our effective tax rates for the three months ended March 31, 2018 and 2017 were 2 8 % and 14% , respectively. Our rates generally differ from the U.S. federal statutory rates of 21% and 35% for the three months ended March 31, 2018 and 2017, respectively, as a result of state income taxes and differing foreign income tax rates. The 2018 effective tax rate exceeds the U.S. statutory rate primarily as a result of pre-tax losses in certain foreign jurisdictions with no corresponding tax benefit. The 2017 effective tax rate was significantly below the U.S. statutory rate as a result of the adoption of ASU 2016-09, Compensation – Stock Compensation , which resulted in a discrete tax benefit of $2 million related to the vesting of stock awards. As of December 31, 2017, we recorded provisional tax estimates associated with the passage of the Tax Cuts and Jobs Act of 2017 (the “Tax Act”). These provisional amounts included a $57 million benefit for the re-measurement of deferred tax assets and liabilities and a $7 million transition tax expense related to undistributed foreign earnings. In accordance with the Securities and Exchange Commission’s Staff Accounting Bulletin No. 118 (“SAB 118”), these provisional amounts will be finalized during 2018. Any adjustments required to the provisional amounts will be reflected in income tax expense in the period the adjustment is identified.

Redeemable Preferred Stock [Abstract]
Redeemable Preferred Stock	NOTE 6 – REDEEMABLE PREFERRED STOCK Preferred Stock Issuance In June 2015, we issued 363,000 shares of Series A Convertible Perpetual Preferred Stock (the “Preferred Stock”) and received proceeds of $3 55 million , net of transaction fees . The Preferred Stock ranks senior to our common stock with respect to dividend rights and rights on liquidation, winding-up and dissolution. The Preferred Stock has a stated value of $1,000 per share, and holders of Preferred Stock are entitled to cumulative dividends payable quarterly in cash at a rate of 6.50% per annum. Holders of Preferred Stock are entitled to vote together with the holders of the common stock as a single class, in each case, on an as-converted basis, except where a separate class vote of the common stockholders is required by law. Holders of Preferred Stock have certain limited special approval rights, including with respect to the issuance of pari passu or senior equity securities of the Company. The Preferred Stock is convertible at the option of the holders into shares of common stock at an initial conversion rate of 55.9284 shares of common stock for each share of Preferred Stock, which represents an initial conversion price of $17.88 per share of common stock, subject to adjustment. On or after the fifth anniversary of the initial issuance of the Preferred Stock, the Company will have the option to redeem, in whole but not in part, all the outstanding shares of Preferred Stock at 105% of par value , subject to certain redemption price adjustments on the basis of the date of the conversion. After the seventh anniversary of the initial issuance of Preferred Stock, the Company will have the option to redeem all of the outstanding shares of Preferred Stock at par value. We may elect to convert the Preferred Stock, in whole but not in part, into the relevant number of shares of common stock on or after the 54th month after the initial issuance of the Preferred Stock if the last reported sale price of the common stock has been at least 150% of the conversion price then in effect for a specified period. The conversion rate is subject to customary anti-dilution and other adjustments.  Holders of the Preferred Stock may, at their option, require the Company to repurchase their shares in the event of a fundamental change, as defined in the agreement. The repurchase price is based on the original $1,000 per share purchase price except in the case of a liquidation in which case they would receive the greater of $1,000 per share and the amount that would be received if they held common stock converted at the conversion rate in effect at the time of the fundamental change. Because this feature could require redemption as a result of the occurrence of an event not solely within the control of the Company, the Preferred Stock is classified as temporary equity on our balance sheet.

Stockholders' Equity [Abstract]
Stockholders' Equity	NOTE 7 – STOCKHOLDERS’ EQUITY Share Repurchase Program In November 2015 , the Company’s board of directors authorized a share repurchase program for common stock up to $100 millio n, which was increased in November 2016 to $125 million. In the first quarter of 2017, the Company completed the repurchase of all shares authorized under the program.  In October 2017, the Company’s board of directors authorized a new share repurchase program for common stock of up to $100 million. The program is scheduled to expire December 31, 2018 . The shares may be repurchased at management’s discretion in the open market. Depending on market conditions and other factors, these repurchases may be commenced or suspended from time to time without prior notice. There were 90,528,319 shares of common stock outstanding as of March 31, 2018 .    Summary of share repurchase activity under the repurchase program s :   Three Months Ended  March 31, March 31,  2018 2017  Number of shares acquired on the open market 1,726,825 859,830  Average price per share $ 17.39 $ 20.54  Total cost of acquired shares (in millions) $ 30 $ 18  Subsequent to quarter end, we purchased an additional 1,144,379 shares for $20 million completing the repurchase of all shares authorized under the October 2017 program. In total, under both programs, we have acquired 14,622,930 shares at an average price per share of $15. 38 fo r a total cost of $225 million. As of April 27, 2018, we had 89,682,844 shares of common stock outstanding.  Equity Compensation Plans  Our 2011 Omnibus Incentive Plan originally had 3 ,250,000 shares reserved for issuance under the plan. In April 2015, our shareholders approved an additional 4,250,000 shares for reservation for issuance under the plan. The plan permits the issuance of stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, performance units and other stock-based and cash-based awards. Since the adoption of the 2011 Omnibus Incentive Plan, the Company’s Board of Directors has periodically granted stock options , restricted stock awards, restricted stock units and performance share units to directors and employees. Options and stock appreciation rights may not be granted at prices less than the fair market value of our common stock on the date of the grant, nor for a term exceeding ten years. For employees, vesting generally occurs over a three to five year period on the anniversaries of the date specified in the employees’ respective stock option, restricted stock award, restricted stock unit and performance share unit award agreement s , subject to accelerated vesting under certain circumstances set forth in the agreements. Vesting for directors generally occurs on the on e -y ear anniversary of the grant date . In the quarter ended March 31, 2018 , 222,435 pe rformance share unit awards and 502,582 shares of restricted stock units have been granted to employees and members of our board of directors. To date , since the plan’s inception in 2011, before consideration of forfeitures , 6,595,947 shares have been granted to management, members of our board of directors and key employees under this plan. A Black-Scholes option-pricing model is used to estimate the fair value of the stock options. A Monte Carlo simulation is completed to estimate the fair value of performance share unit awards with a stock price performance component. We expense the fair value of all equity grants , including performance share unit awards, on a straight-line basis over the vesting period.  Accumulated Other Comprehensive Loss  Accumulated other comprehensive loss in the accompanying consolidated balance sheets consists of the following (in millions):    March 31, December 31,  2018 2017  Currency translation adjustments $ (210) $ (209)  Pension related adjustments (1) (1)  Hedge accounting adjustments (1) -  Accumulated other comprehensive loss $ (212) $ (210) Earnings per Share Earnings per share are calculated in the table below (in millions , except per share amounts).

For the three months ended March 31, 2018 and 2017 , all of the shares of the Preferred Stock were anti-dilutive. For the three months ended March 31, 2018 and 2017 , we had approximately 3.4 million and 2 .1 million anti-dilutive stock options , respectively . There were no anti-dilutive restricted stock, restricted units or performance stock unit awards for the three months ended March 31, 2018 . There were 1. 4 million anti-dilutive restricted stock, restricted units or performance stock unit awards for the three months ended March 31, 2017 .

Segment Information [Abstract]
Segment Information	NOTE 8 – SEGMENT INFORMATION Our business is comprised of four operating segments : U.S. Eastern Region and Gulf Coast , U.S. Western Region, Canada and International. Our International segment consists of our operations outside of the U.S. and Canada. These segments represent our business of selling PVF to the energy sector across each of the upstream (exploration, production and extraction of underground oil and gas), midstream (gathering and transmission of oil and gas, gas utilities, and the storage and distribution of oil and gas) and downstream (crude oil refining and petrochemical and chemical processing and general industrials ) markets.

Revenue [Abstract]
Revenue	NOTE 9 - REVENUE  Adoption of ASC 606, "Revenue from Contracts with Customers"  On January 1, 2018, we adopted ASC 606 using the modified retrospective method applied to those performance obligations which were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under ASC 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under ASC 605.  Revenue Recognition  Revenue is recognized when control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Our disaggregated revenue represent s our business of selling PVF to the energy sector across each of the upstream (exploration, production and extraction of underground oil and gas), midstream (gathering and transmission of oil and gas, gas utilities, and the storage and distribution of oil and gas) and downstream (crude oil refining and petrochemical and chemical processing and general industrials ) markets in each of our reportable segments . Each of our end markets and geographical reportable segments are impacted and influenced by varying factors, including macroeconomic environment, commodity prices, maintenance and capital spending, and exploration and production activity. As such, we believe that this information is important in depicting the nature, amount, timing and uncertainty of our contracts with customers.  The following table presents our revenue disaggregated by revenue source (in millions):     Three Months Ended  March 31,   U.S. Canada International Total  2018:  Upstream $ 178 $ 57 $ 67 $ 302  Midstream 393 14 3 410  Downstream 235 7 56 298  $ 806 $ 78 $ 126 $ 1,010  2017:  Upstream $ 140 $ 61 $ 44 $ 245  Midstream 346 11 14 371  Downstream 180 5 61 246  $ 666 $ 77 $ 119 $ 862

Fair Value Measurements [Abstract]
Fair Value Measurements	NOTE 10 – FAIR VALUE MEASUREMENTS From time to time, we use derivative financial instruments to help manage our exposure to interest rate risk and fluctuations in foreign currencies. Interest Rate Swap : In March 2018, we entered into a five -year interest rate swap that became effective on March 31, 2018, with a notional amount of $250 million from which the C ompany will receive payments at 1-month LIBOR and make monthly payments at a fixed rate of 2.7145% with settlement and reset dates on or near the last business day of each month until maturity. The fair value of the swap at inception was zero . We have designated the interest rate swap as an effective cash flow hedge utilizing the guidance under ASU 2017-12. As such, the valuation of the interest rate swap is recorded as an asset or liability, and the gain or loss on the derivative is recorded as a component of other comprehensive income. I nterest rate swap agreements are reported at fair value utilizing Level 2 inputs. We obtain dealer quotations to value our interest rate swap agreements. The fair value of our interest rate swap is estimated based on the present value of the difference between expected cash flows calculated at the contracted interest rates and the expected cash flows at current market interest rates. We recognize interest rate swaps on the accompanying balance sheet at fair value using observable inputs such as yield curves and other market-based factors . We recorded a liability of $1 million at March 31, 2018. Foreign Exchange Forward and Option Contracts : Foreign exchange forward contracts are reported at fair value utilizing Level 2 inputs, as the fair value is based on broker quotes for the same or similar derivative instruments. O ur foreign exchange derivative instruments are freestanding and, accordingly, changes in their fair market value are recorded in earnings. The total notional amount of our forward foreign exchange contracts and options was approximately $41 million and $60 million at March 31, 2018 and December 31, 2017 , respectively. We had approximate ly $0 million recorded as liabilities on our consolidated balance sheets as of March 31, 2018 and December 31, 2017 .  With the exception of long-term debt, the fair values of our financial instruments, including cash and cash equivalents, accounts receivable, trade accounts payable and accrued liabilities approximate carrying value. The carrying value of our debt w as $639 million and $526 m illion at March 31, 2018 and December 31, 2017 , respectively. We estimate the fair value of the Term Loan using Level 2 inputs, or quoted market prices. The fair value of our debt was $ 645 million and $533 million at March 31, 2018 and December 31, 2017, respectively.

Commitments and Contingencies [Abstract]
Commitments and Contingencies	NOTE 11 – COMMITMENTS AND CONTINGENCIES Litigation As bestos Claims. We are one of many defendants in lawsuits that plaintiffs have brought seeking damages for personal injuries that exposure to asbestos allegedly caused. Plaintiffs and their family members have brought these lawsuits against a large volume of defendant entities as a result of the defendants’ manufacture, distribution, supply or other involvement with asbestos, asbestos containing-products or equipment or activities that allegedly caused plaintiffs to be exposed to asbestos. These plaintiffs typically assert exposure to asbestos as a consequence of third-party manufactured products that our MRC Global (US) Inc. subsidiary purportedly distributed. As of March 31, 2018 , we are named a defendant in approximately 533 l awsuits involving approximately 1,143 claims . No asbestos lawsuit has resulted in a judgment against us to date, with a majority being settled, dismissed or otherwise resolved. Applicable third-party insurance has substantially covered these claims, and insurance should continue to cover a substantial majority of existing and anticipated future claims. Accordingly, we have recorded a liability for our estimate of the most likely settlement of asserted claims and a related receivable from insurers for our estimated recovery, to the extent we believe that the amounts of recovery are probable. It is not possible to predict the outcome of these claims and proceedings. However, in our opinion , th e likelihood that the ultimate disposition of any of these claims and legal proceeding s will have a material adverse effect on our consolidated financial statements is remote . Other Legal Claims and Proceedings. From time to time, we have been subject to various claims and involved in legal proceedings incidental to the nature of our businesses. We maintain insurance coverage to reduce financial risk associated with certain of these claims and proceedings. It is not possible to predict the outcome of these claims and proceedings. However, in our opinion, th e likelihood that the ultimate disposition of any of these claims and legal proceeding s will have a material adverse effect on our consolidated financial statements is remote. Product Claims. From time to time, in the ordinary course of our business, our customers may claim that the products that we distribute are either defective or require repair or replacement under warranties that either we or the manufacturer may provide to the customer. These proceedings are, in the opinion of management, ordinary and routine matters incidental to our normal business. Our purchase orders with our suppliers generally require the manufacturer to indemnify us against any product liability claims, leaving the manufacturer ultimately responsible for these claims. In many cases, state, provincial or foreign law provides protection to distributors for these sorts of claims, shifting the responsibility to the manufacturer. In some cases, we could be required to repair or replace the products for the benefit of our customer and seek our recovery from the manufacturer for our expense. In our opinion, th e likelihood that the ultimate disposition of any of these claims and legal proceeding s will have a material adverse effect on our consolidated financial statements is remote .  Customer Contracts  We have contracts and agreements with many of our customers that dictate certain terms of our sales arrangements (pricing, deliverables, etc.). While we make every effort to abide by the terms of these contracts, certain provisions are complex and often subject to varying interpretations. Under the terms of these contracts, our customers have the right to audit our adherence to the contract terms. Historically, any settlements that have resulted from these customer audits have not been material to our consolidated financial statements.  Purchase Commitments We ha v e purchase obligations consisting primarily of inventory purchases made in the normal course of business to meet operating needs. While our vendors often allow us to cancel these purchase orders without penalty, in certain cases, cancellations may subject us to cancellation fees or penalties depending on the terms of the contract .

Background and Basis of Presentation (Policy)	3 Months Ended

Background and Basis of Presentation [Abstract]
Business Operations	Business Operations : MRC Global Inc. is a holding company headquartered in Houston, Texas. Our wholly owned subsidiaries are global distributors of pipe, valves, fittings (“PVF”) and related products and services across each of the upstream (exploration, production and extraction of underground oil and gas), midstream (gathering and transmission of oil and gas, gas utilities, and the storage and distribution of oil and gas) and downstream (crude oil refining and petrochemical and chemical processing and general industrials ) sectors. We have branches in principal industrial, hydrocarbon producing and refining areas throughout the United States, Canada, Europe, Asia , Australasia , the Middle East and Caspian . Our products are obtained from a broad range of suppliers. 
Basis of Presentation	Basis of Presentation : We have prepared our unaudited condensed consolidated financial statements in accordance with Rule 10-01 of Regulation S-X for interim financial statements. These statements do not include all information and footnotes that generally accepted accounting principles require for complete annual financial statements. However, the information in these statements reflects all normal recurring adjustments which are, in our opinion, necessary for a fair presentation of the results for the interim periods. The results of operations for the three months ended March 31, 2018 are not necessarily indicative of the results that will be realized for the fiscal year ending December 31, 2018 . We have derived our condensed consolidated balance sheet as of December 31, 2017 from the audited consolidated financial statements for the year ended December 31, 2017 . You should read these condensed consolidated financial statements in conjunction with the audited consolidated financial statements and notes thereto for the year ended December 31, 2017 .  The consolidated financial statements include the accounts of MRC Global Inc. and its wholly owned and majority owned subsidiaries (collectively referred to as the “Company” or by such terms as “we,” “our” or “us”). All material intercompany balances and transactions have been eliminated in consolidation.
Recent Accounting Pronouncements	Recent Accounting Pronouncements : In February 2016, the Financial Acco unting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, Leases, which will replace the existi ng guidance in ASC 870, Leases. This ASU requires a dual approach for lessee accounting under which a lessee would account for leases as finance leases or operating leases. Both finance leases and operating leases will result in the lessee recognizing a right-of-use asset and a corresponding lease liability. For finance leases, the lessee would recognize interest expense and amortization of the right-of-use asset, and for operating leases, the lessee would recognize a straight-line total lease expense. This guidance is effective for annual and interim reporting periods of public entities beginning after December 15, 2018. We are in the process of evaluating the effect of the adoption of ASU 2016-02 on our consolidated financial statements. Adoption of New Accounting Standards : ASU 2014-09, Revenue - Revenue from Contracts with Customers . On January 1, 2018, we adopted accounting standard ASC 606, Revenue from Contracts with Customers (“new revenue standard”) using the modified retrospective method. Under this method, a cumulative effect of initially applying the new revenue standard requires an adjustment to the opening balance of retained earnings, and the comparative information continues to be reported under the accounting standards in effect for those periods prior to adoption . The cumulative effect of initially applying the new standard was immaterial to our consolidated financial statements. Under the new revenue standard, revenue is recognized when control of the promised goods or services is transferred to our customers in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Substantially all of our revenue is recognized when products are shipped or delivered to our customers, and payment is due from our customers at the time of billing with a majority of our customers having 30 day terms. Returns are estimated and recorded as a reduction of revenue. A mounts received in advance of shipment are deferred and recognized when the performance obligations are satisfied . Sales taxes collected from customers and remitted to governmental authorities are accounted for on a net basis and , therefore , are excluded from sales in the accompanying consolidated statements of operations. Cost of sales includes the cost of inventory sold and related items, such as vendor rebates, inventory allowances and reserves, and shipping and handling costs associated with inbound and outbound freight, as well as depreciation and amortization and amortization of intangible assets. In some cases, particularly with third party pipe shipments, shipping and handling costs are considered separate performance obligations, and as such, the revenue and cost of sales are recorded when the performance obligation is fulfilled.  Our contracts with customers ordinarily involve performance obligations that are one year or less. Therefore, we applied the standard’s optional exemption that permits the omission of information about our unfulfilled performance obligation s as of the balance sheet dates . ASU 2017-12 , Accounting for Derivatives and Hedging Transactions (Topic 815) Targeted Improvements to Accounting for Hedging Activities . In March 2018, we early adopted ASU 2017-12. The new standard amends the hedge accounting model to better portray an organization’s risk management activities in the financial statements, as well as simplifies the applications of certain hedge accounting guidance. The implementation of ASU 2017-12 did not have a material impact on our consolidated financial statements.
