HDPE Double wall corrugated pipe extrusion line

HDPE Double wall corrugated pipe extrusion line Main features -- 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 extruding. -- A 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. -- The 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. -- The key and new product of the State. -- It is certified for CE quality system by China Quality Certification Centre.
