从China供应商批发进口406 Steel Pipe — FOB条款

This listing covers a 406.4 mm LSAW steel pipe produced by Winsteel Group Co., Ltd., with an outer diameter of 406.4 mm, a wall thickness of 12.7 mm, and a length of 12.0 m. The pipe meets API 5L PSL 1 Grade B standards, a common specification for line pipe in the oil and gas industry. Surface treatment is bare or black vanished, and each piece is marked with its dimensions, production date, API number, heat number, and pipe number for traceability.

LSAW (Longitudinal Submerged Arc Welded) pipes like this are manufactured from steel plates rolled into a cylinder and welded along the longitudinal seam. API 5L PSL 1 Grade B indicates a yield strength of 241 MPa and tensile strength of 414 MPa, typical for carbon steel pipes used in low to medium pressure applications. The pipe’s bare or black vanished surface provides basic corrosion protection, while additional coatings can be applied for harsher environments.

These pipes are primarily used in oil and gas transportation, structural applications, and water pipelines. Buyers typically source them in bulk for infrastructure projects, with lead times and logistics varying by order size. The 12-meter length is standard for reducing joint counts in long-distance pipelines, and the API 5L certification ensures compliance with international quality and safety standards for line pipe.

Winsteel Group Co., Ltd. is based in Yachuan Jiayuan, Nankai District, Tianjin, China. The company specialises in the production of steel pipes, including LSAW and other varieties, catering to industrial and infrastructure markets. Its address in Tianjin, a major port city, positions it well for both domestic distribution and international exports, particularly for bulk shipments.

The supplier is listed with a harbor trust tier, indicating a baseline level of verification. However, the response rate and average response hours are currently unavailable, which may affect communication efficiency. Winsteel Group Co., Ltd. focuses on delivering products that meet international standards, as evidenced by the API 5L certification for this 406.4 mm steel pipe.
