Import Erw Alloy Steel Pipe — Buy in wholesale FOB from Supplier in China

ERW alloy steel pipe is manufactured through electric resistance welding, producing a longitudinal seam with consistent wall thickness and dimensional accuracy. This listing specifies the product as ERW alloy steel pipe, with no exact dimensions or grades provided, but industry standards typically apply: wall thickness ranges from 1.5 mm to 12.7 mm, and outer diameters commonly span 10 mm to 610 mm. The material composition is not listed, but alloy steel grades such as ASTM A335 P11 or P22 are common for high-pressure applications.

ERW pipes in this category are typically made from low-alloy steels with chromium, molybdenum, or vanadium to enhance strength and corrosion resistance under elevated temperatures. The welding process ensures tighter tolerances than seamless alternatives in smaller diameters, reducing material weight without sacrificing structural integrity. These pipes are not certified to any standard in the listing, but in practice, they are often tested for hydrostatic pressure, non-destructive examination, and chemical composition verification per ASTM A53 or API 5L.

These pipes are primarily purchased by contractors in oil and gas, power generation, and chemical processing industries for fluid transport under moderate pressure. Buyers often require them for above-ground pipelines, structural supports, and heat exchanger systems. Trade terms are not specified, but standard packaging includes bundling with steel straps and protective end caps. Buyers should confirm the exact alloy composition, heat treatment status, and test reports before ordering.

Threeway Steel Co., Ltd. is listed as an imported supplier based in Changsha, Hunan, China, with a physical address registered in the Royal Wing Tower. The supplier's trust tier is classified as harbor, indicating basic verification of business existence but no third-party audit or production site inspection. The response rate and average response time are both zero, suggesting no active communication channels are currently operational on this platform.

The listing does not provide details on production capacity, years in operation, workforce size, or export history. There is no mention of certifications, quality control labs, or client references. The supplier appears to operate as a trading entity rather than a manufacturer, sourcing ERW steel pipe from third-party mills. Buyers should request independent verification of material origin and testing before placing orders.
