Import Api 5l Gr.B Steel Pipe — Buy in Bulk from Supplier in China

Hebei Smart Steel Pipe Mill Co., Ltd supplies API 5L Gr.B seamless steel pipe with outer diameter ranging from 21.3 mm to 711 mm (1/4 inch to 28 inch) and wall thickness from 2 mm to 40 mm, covering SCH 40, SCH 80 and SCH 160 schedules. The material conforms to ASTM SA106/SA53 GRB, API 5L Gr.B, A179, A333 GR6, and grades X42 through X60, with domestic Chinese grades 10#, 20# and 45# also acceptable. Standard lengths run 6-12 metres, and the pipes are hot-finished seamless. The supplier notes capability to develop products to client-specific requirements beyond listed standards.

Typical industry context for API 5L Gr.B places this grade in the PSL1/PSL2 pipeline steel category, with minimum yield strength of 241 MPa and tensile strength of 414 MPa, though buyers should confirm the supplier's actual mill test certificates for exact mechanical properties. The Gr.B designation permits lower carbon equivalent than higher API grades, improving weldability for field construction. Standard manufacturing involves hot rolling or hot extrusion of solid billets, followed by sizing and heat treatment. For pressure service, Gr.B is commonly dual-certified to ASTM A106 Grade B where chemistry overlaps, but the supplier does not explicitly state dual certification. The pipe receives surface treatment of paint varnish or oil coating as standard practice for corrosion protection during shipment and storage.

Applications span low and medium pressure boilers, high pressure boilers, ship-building, liquid service, petroleum cracking, chemical fertilizer equipment, electric power, oil-drawing equipment and structural purposes. Buyers in Middle East, Southeast Asia, Europe, South America and Africa represent the supplier's stated export markets. The pipe ships with bevelled ends, plastic caps, bundle packing and seaworthy packaging. Incoterms, exact MOQ and lead time are not specified in the listing; importers should confirm these directly with Hebei Smart Steel Pipe Mill Co., Ltd before placing orders.
