    API 5L Grade B Pipe Buyer FAQs


    What is the minimum order quantity for Grade B pipe?

    MOQ varies by size; smaller diameters allow lower tonnage while large OD needs mill minimums.

    Is Grade B pipe suitable for sour service?

    Standard Grade B is not sour rated; choose PSL2 with NACE MR0175 compliance for H2S service.

    Can Seamless and ERW be supplied in the same order?

    Yes, mixed manufacturing types can ship together if each bundle is tagged separately.

    What is the usual lead time?

    Ex-stock sizes dispatch within days; custom rolled sizes depend on mill production slot.
