Import Electric Resistance Welded Steel Pipe — Buy in Bulk from Supplier in China

Electric resistance welded steel pipe from Threeway Steel Co., Ltd is manufactured to meet API 5L and ASTM A53 standards, with available grades including Gr B, X42, X46, X56, X60, X65, and X70. The pipes are produced using continuous electric resistance welding, ensuring a consistent longitudinal seam with minimal distortion. Dimensions range from 1/2 inch to 24 inch outer diameter, with wall thicknesses from 1.65 mm to 12.7 mm, depending on schedule and application. These specifications are derived directly from the supplier's product data.

The base material is carbon steel with controlled manganese and silicon content, typical for ERW applications requiring moderate strength and weldability. Corrosion resistance is achieved through internal and external coatings such as epoxy or 3LPE, though exact coating thickness is not specified. The pipe's microstructure is normalized post-weld to reduce residual stress, a standard practice in industrial-grade ERW pipe production. Surface finish is mill-scaled unless otherwise requested, and end preparation follows ANSI B16.25 bevel standards.

These pipes are commonly used in oil and gas transmission lines, water distribution networks, and structural framing in industrial construction. Buyers include pipeline contractors, municipal infrastructure projects, and mechanical engineering firms. Trade terms include FOB Changsha Port and CIF destinations, with packaging in bundles secured with steel straps. Minimum order quantity is not stated and must be confirmed with the supplier.
