Our full-automatic natural gas furnace (24 meters in length) maintains precise temperature control with real temperature tolerance within 10ºC.
Pipe of Grades P1, P2, and P12 (hot finished or cold drawn) 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
