Our seamless carbon steel pipes are manufactured from high-quality grades including ASTM A106, API 5L, and ASTM A53, available in sizes from 1/8" to 24" OD with wall thicknesses of SCH10 to SCH160. These pipes feature excellent pressure resistance and durability, making them ideal for oil & gas, petrochemical, and high-pressure fluid transportation applications. Custom lengths (6m-12m) and end treatments (beveled, threaded) available.

Produced using precision hot-rolled or cold-drawn processes, our seamless pipes undergo strict quality control during piercing, elongation, and sizing. Equipped with automated ultrasonic testing (UT) and eddy current inspection systems, we ensure consistent wall thickness (±10%) and superior internal/external surface 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.
