Heat Treatment Assurance

Our full-automatic natural gas furnace, 24 meters in length, maintains precise temperature control with real temperature tolerance within 10ºC. We follow recommended tempering procedures to ensure optimal performance for high-temperature applications.

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

Quality Assurance

Each lot of raw materials tested by spectrometer before storage
100% PMI testing of mother pipe to ensure correct material
100% PMI testing of finished pipe to verify correct grade
