Our carbon steel welded pipes are available in sizes ranging from 1/2" to 24" OD with wall thicknesses of SCH10 to SCH80, manufactured from high-quality grades including ASTM A53, API 5L, and ASTM A135. These pipes feature excellent weld integrity and dimensional consistency, making them ideal for low-pressure fluid transportation, structural applications, and fencing systems. Custom lengths (6m-12m) and surface treatments (galvanized, black painted) available upon request.

Our carbon steel welded pipes are manufactured using advanced ERW (Electric Resistance Welding) or LSAW (Longitudinal Submerged Arc Welding) technology. The production process incorporates precision forming systems with automatic seam tracking, in-line heat treatment for stress relief, automated ultrasonic testing for weld integrity, and computer-controlled cutting to length. These integrated measures ensure strict wall thickness tolerance of ±10% and consistent product quality.

The manufacturing process utilizes a fully automated intelligent control system with digital monitoring from raw material pretreatment through continuous rolling and annealing treatment. Equipped with German-engineered 4-high reversible rolling mills and continuous annealing furnaces, we ensure consistent mechanical properties throughout each coil. Online non-destructive testing equipment provides real-time surface defect and microstructure inspection, while precision slitting units guarantee perfect coiling flatness. Our ISO9001-certified production involves 16 quality checkpoints from molten steel to finished products, ensuring uncompromising quality throughout the entire manufacturing process.

Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
