Production Technique

Quality Control Mechanism

 Raw material inspection → leveling inspection → butt welding inspection → forming test → internal welding inspection → external welding inspection → pipe cutting test →ultrasonic test → beveling → dimension examination → X-ray test → hydrostatic test → Final Quality Control

Anti-Corrosion Measures

PP PE 3PE HDPE Epoxy Coated, to protect the welded pipes from atmospheric corrosion.
