FAQ

API 5L line pipe buying questions

Which API 5L line pipe grades can Yuxinda review?
The approved PSL1 range is Grades B through X70. PSL2 seamless line pipe is listed for X42 through X65, while LSAW requirements can extend through X80/L555. The final grade, size, construction and testing scope are confirmed against the line list.
What is the difference between API 5L PSL1 and PSL2?
PSL1 and PSL2 are product specification levels within API 5L / ISO 3183. PSL2 generally adds more stringent chemistry, testing, impact and documentation controls. Select the level required by the governing project specification, not by price alone.
Can API 5L line pipe be supplied seamless or welded?
Seamless and LSAW routes are represented in the current product pages. The manufacturing route is confirmed for the final diameter, wall thickness, grade, quantity and inspection requirement before quotation.
What is the minimum order for API 5L line pipe?
The minimum order is 28 metric tonnes. Sizes and grades can be mixed in one order, subject to the final specification, production review and signed contract.
What documents are available for an API 5L line pipe order?
A manufacturer-issued EN 10204 3.1 mill test certificate is provided for the corresponding contract and production batch. Packing list, commercial invoice, bill of lading and certificate of origin are included. Hydrostatic or NDT reports and coating reports are quoted separately when required.
What information is needed for an API 5L line pipe quotation?
