Heat Treatment Assurance
Our full-automatic natural gas furnace, 24 meters in length, ensures precise temperature control with real temperature tolerance within 10ºC.
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 be given final heat treatment at 1200°F [650°C] to 1300°F [705°C]. All Grade P5c pipes receive final heat treatment from 1325°F [715°C] to 1375°F [745°C].
Quality Assurance
  • 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
