HDPE hollow wall winding pipe production line

Short Description:

The extrusion line is mainly for producing hollow wall winding pipe. HDPE hollowness winding pipe has small masses and a low roughness coefficient, are widely used for sewerage systems, storm drains, treatment facilities and sanitation of the old pipeline, well and various sewage tanks are manufactured. Pipes with diameters from 200mm-4000mm and the stiffness classes SN 2,4,6,8,10,12,14,16. Pipe extrusion line first produces square pipes from HDPE, then with the help of a co-extruder and spiral molding machine, spirally wound onto the walls and subsequently welded together forming the pipe body. Pipe extrusion and winding system are separately controlled, can be used separately. The line energy saving, easy to transport and installation, the investment is lower, easy to maintain.
