PE PP spiral winding pipe extrusion line

Spiral pipe production line can produce spiral wound pipes with diameters from 200mm to 5000mm. The production line produces square or rectangular HDPE profile, which are then spiral wound to form large diameter round pipes. The line is energy efficient and easy to transport and install. Low investment and easy to maintain. Hollow wall spiral wound pipe with light quality and low roughness coefficient is widely used in buried drainage and sewage system, rainwater discharge and collection, inspection wells, local sewage treatment system and so on.The maximum diameter of the hollow wall spiral wound pipe can reach 5 meters. Ring stiffness SN 2, 4, 8, 10, 12.5, 16. Hollow wall spiral pipe has profile structure wall with smooth and flat inner and outer wall. It can be made into double-layer, triple-layer, four-layer or customized according to samples.
