从China供应商批发进口A671 Gr.B 60 Cl32 Lsaw Steel Pipe — FOB条款

The A671 Gr.B 60 Cl32 LSAW steel pipe from Canzhou Qieernuo Steel Pipe Co., Ltd. is a longitudinal submerged arc welded carbon steel pipe manufactured to ASTM A671 electric-fusion-welded standards. The pipe covers outer diameters from 457.2 mm to 1422.2 mm, wall thicknesses from 7 mm to 35 mm, and standard lengths of 5 to 12 metres. The Class 32 designation signals pressure-rated construction for high-stress transmission environments, with the Gr.B material designation indicating a carbon steel chemistry suited to moderate temperature service.

The longitudinal weld process deposits fusion metal along the pipe seam under submerged flux, producing a consistent, inspectable joint with mechanical properties matching the parent plate. The source material is supplied in accordance with API 5L PSL 1 and PSL 2 grades including B, X42 through X80, as well as EN10219 S275JRH, S275J0H, S275J2H, S355JRH, S355J0H and S355J2H. Surface finish options include bare black or anti-corrosion coating; end protectors are plastic caps. Standard testing covers hydraulic pressure testing, ultrasonic inspection, or X-ray examination to verify weld integrity and wall soundness.

Importers deploy this pipe in oil and gas transmission lines, refinery process piping, offshore platform construction, water infrastructure, and structural casing applications. The heavy wall range up to 35 mm suits high-pressure sour service and deepwater environments where collapse resistance is critical. Bundled or single-length packaging is arranged for containerized and bulk sea freight from Xingang port. Buyers should confirm the exact steel grade, heat treatment condition, and inspection certificate scope before finalising technical queries.
