A355 Carbon Steel Pipe

Update : 2026-02-02

A355 Carbon Steel Pipe
ASTM A355 Carbon Steel Pipe is a chromium-molybdenum alloy steel pipe engineered for high-temperature and high-pressure industrial service, available in grades like P11 and P22 with seamless and welded variants. It exhibits exceptional high-temperature strength, creep and oxidation resistance, maintaining stable mechanical properties under continuous elevated temperature operation. Featuring excellent weldability and machinability for on-site fabrication, it has uniform wall thickness and precise dimensional tolerance. Certified for harsh working conditions, it’s a core high-performance pipe for industrial high-temperature and high-pressure fluid conveyance.
