Overview

Welded API 5L line pipe is offered for pipeline export packages when the project accepts ERW or other welded manufacturing routes under API 5L. Confirm grade (for example B or X42–X70 class), PSL1 or PSL2, OD, wall, end bevel, length, and hydro plus weld NDT scope before quotation. Mill test documents and heat marks must support destination acceptance, and packing should suit export loading. Send the MTO size list, quantity, coating needs, destination port, and inspection preference for a clear commercial path with Tsingshan Steel.
