Heat Treatment Assurance

Our facility features a fully-automatic natural gas furnace measuring 24 meters in length, capable of maintaining temperature tolerance within 10ºC. For optimal performance, tempering temperature should be at least 50°C above intended service temperature. Please advise if service temperature exceeds 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
