Large Size Spiral Steel Pipe Production Line:
At present, the demand of drain pipe exceeds its supply and is becoming a hot field of investment. The large size spiral steel pipe production extrusion line equipment and its technology for the corrugated pipe winded with steel strip were developed in the 1990’s. They are now widely used in many fields in the developed countries, especially for water, drainage, sewerage piping in industries and agriculture in USA, Canada, Japan, Korea and the European countries. An extrusion line for the corrugated pipe winded by steel strip is newly presented us, combining international advanced technologies, with a diameter range of ID 800 mm—3,500 mm.
