API 5L Seamless Pipe FAQs
What is the minimum order quantity?
MOQ varies by size and grade; smaller diameters typically allow lower tonnage orders.
Can you supply mixed grades in one container?
Yes, mixed-grade or mixed-size loading is possible as long as each bundle is tagged and segregated for traceability.
Do you provide third-party inspection call?
Yes, we accommodate SGS, Bureau Veritas, TÜV or client-nominated inspectors before dispatch at buyer's cost.
What is the typical lead time?
Ex-stock sizes ship faster; custom rolled sizes depend on mill production slot.
