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, we recommend tempering temperatures at least 50°C above intended service temperatures.

Quality Assurance

Each lot of raw materials undergoes spectrometer testing before storage
100% Positive Material Identification (PMI) of mother pipe to ensure correct material
100% PMI of finished pipe to verify correct grade production
