Our carbon steel welded pipes are manufactured from high-quality materials complying with international standards 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 and surface treatments are available upon request to meet specific project requirements.

Our carbon steel welded pipes are manufactured using advanced ERW (Electric Resistance Welding) or LSAW (Longitudinal Submerged Arc Welding) technology, featuring 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. we maintain strict wall thickness tolerance of ±10% to ensure consistent product quality.

In order to ensure product quality, we will arrange professional personnel to check product quality, packaging, weight, hardness, etc., according to customer requirements of product specifications, looking for high-quality and cheap cooperative factories in China, to provide customers with one-stop procurement services and quality assurance.

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.
