High-quality cold rolled/cold drawn alloy steel seamless pipes designed for annealing and quenching applications, available in diameters from 40mm to 360mm.

Our facility features a full-automatic natural gas furnace with 24 meters in length, maintaining real temperature tolerance within 10ºC for precise heat treatment control.

Important Note: It is recommended that the tempering temperature should be at least 100°F [50°C] above the intended service temperature. Please advise if service temperature exceeds 1100°F [600°C].

Pipes of Grades P1, P2, and P12 may receive final heat treatment at 1200°F[650°C] to 1300°F [705°C]. All Grade P5c pipes receive final heat treatment in the range from 1325°F [715°C] to 1375°F[745°C].

• Each lot of raw materials tested by spectrometer before storage
• 100% PMI (Positive Material Identification) of mother pipe to ensure correct material
• 100% PMI of finished pipe to verify correct grade production

High pressure, low & medium pressure boiler steel pipes/tubes are suitable for manufacturing super-heaters, re-heaters, water walls, and economizers in large-scale power plants.
