Heat Treatment Assurance
Our facility features a full-automatic natural gas furnace measuring 24 meters in length, capable of maintaining 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].
Quality Assurance
- Each lot of raw materials undergoes spectrometer testing before storage
- 100% PMI (Positive Material Identification) of mother pipe to ensure correct material
- 100% PMI of finished pipe to verify correct grade production
