HDPE Double wall corrugated pipe production line:
- Attain CE certificate
- Recognized by ISO 9001 quality system;
- High efficiency, stability and low cost;
- Own a number of patented technologies;
- 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
