200-1200mm Diameter DWC pipe production line It adopts efficient screw and notched barrel, the inner and outer walls are separately extruded by two extruders for using different materials and ensuring efficient extrudingA high speed of production can be ensured by the corrugated forming system and forced cooling system combined with water and air cooling during constant production;The advanced programmable lubricating system decreases abrasion of mould blocks to a minimum while lengthening their lifespan and ensuring running precision and stable quality.The advanced inline double wall belling function can reach or exceed the requirement of the state standard, completely solving disadvantages of the pipe??s creep and leakage of sealing in sockets.Co-extrusion die with special structure makes the inner and outer walls even and stepless adjustable , and forming stable . The cast mould blocks are made from special alloy for high precision and strength and excellent radiation effect. A professional PCC (B&R, Austria) control system is adopted with 15???? touched colour screen for high automation, reliable running and easy operation. It adopts a quick changing system for the mould blocks.he optimum design of crest provides a perfect combination of higher ring stiffness and lower unit weight.Long-distance communicative function can realize tele-diagnosis and maintenance.This 200-1200mm production line occupy 70% of chinese market and are exported to more than 15 countries in the world. It is certified for CE quality system.
