ASTM A106 seamless carbon steel pipe from TPMC is engineered for high-temperature and high-pressure service. Manufactured using the advanced PQF process, it begins with killed steel solid billets pierced to form a uniform, seamless structure, delivering superior strength and reliability in sustained elevated temperatures thanks to enhanced heat resistance and creep properties.
Our TPMC pipe is widely used in power plants, refineries, petrochemical plants, high-pressure steam/heat transfer systems, and general process piping at elevated temperatures and pressures.
