20# Seamless Steel Pipe

Our 20# Seamless Steel Pipe is manufactured from high-quality carbon structural steel, perfectly suited for mechanical structures, pressure systems, and fluid transportation.

Produced via optimized hot-rolled and cold-drawn processes, these pipes deliver consistent chemical composition and predictable mechanical performance, reliably meeting global industrial specifications. (Note: 20# carbon steel is the Chinese standard equivalent to ASTM A106 Gr.B and API 5L Gr.B).

We ensure full traceability and conformity to global industrial requirements.

Carbon controlled at 0.17–0.23% ensures weldability while maintaining consistent tensile strength for structural applications.

Hot rolling and cold drawing maintain tight dimensional tolerances, reducing on-site machining requirements.

Ultrasonic and eddy current testing help ensure internal integrity and reduce the risk of defects in high-pressure applications.

Automated shot-blasting and uniform black coating provide corrosion protection during storage and shipping.

Production Capacity: Our automated hot-rolling and cold-drawing production lines in Jinan, China, support a monthly export capacity exceeding 20,000 tons, enabling stable lead times for bulk orders.

Strategic Port Access: Positioned between Tianjin Port and Qingdao Port, enabling rapid 24-to-48-hour inland transit to the docks, securing lower freight costs and efficient shipping schedules.

Quality Verification: Every batch is accompanied by a Mill Test Certificate (EN 10204 3.1) and is available for inspection by third-party agencies such as SGS and BV.
