carbon steel pipe line characteristics 1. The pipe internal stress is very small and uniformly distributed after the full- length expansion. The corrosion and cracking of the pipe owing to stress can be effectively prevented. The application of welding on site is very easy because of the high dimension precision;
3. Application:
The products are widely applied to many fields such as petroleum pipeline, natural gas pipeline, urban pipe network, mines pipeline,Coal Water Slurry pipeline, and construction pipe for high voltage, wind power, bridges, high-speed rail steel construction etc.
4. Production Process:
Plate Ultrosonic Inspection → Plate Edge Milling → Plate Edge Crimping → Forming → Continuous Pre-welding → Inside Welding → Outside Welding → Ultrosonic Test1 → X-ray Test1 → Expansion → Finishing → Straightening → Hydraulic Test → Pipe Ends Beveling → Ultrosonic Test 2→ X-ray Test 2→ Appearance Inspection → Coating
