Brief Introduction of Hollow Wall Winding Pipe Production Line

The large-diameter HDPE hollow wall winding pipe production line developed with advanced technology can produce large-diameter drainage pipes with the diameter of 300-3000. The pipe has gradually become the mainstream product of urban drainage pipes and will gradually replace steel pipes, cement pipes and other plastic pipes.

Using high-density polyethylene as the main raw material, the first main extrussewage pipelines in construction, residential quarters, sports fields, squares, mines, agriculture, culverts, bridges and other fields.

ion machine extrudes a rectangular tube into the winding forming machine, and at the same time the second extrusion machine ejects rubber strips and extrudes the composite. Its inner and outer walls are flat and smooth. According to different use conditions, the ring stiffness can be divided into 4 grades, the highest can reach 16kn/m2, which can be adapted to acid-base liquids below 10%. This kind of pipe has the advantages of corrosion resistance, light weight, easy installation, high flow rate, long life (50 years), etc. It can replace pipes made of high energy consumption materials (cement, cast iron, ceramics, etc.), and is widely used in highways and municipal administrations.
