PVC single-wall corrugated pipe extrusion line
Corrugated Pipe Extrusion Line
SJ series of single-screw extruder can apply to produce suchproducts with thermoplasticity as pipes of PP, PE, PS, ABS, PMMA, PVC,as well as plates, sheets, rods, profiles and plastic pellets. Accordingto different raw materials and product specifications, screws withdifferent ratios of length diameter and compression, barrels ofdifferent structures and proper driving devices are adopted so as tomake products with high quality.

High output and low power consumption.
All hard teeth surface bears experienced heat treatment and finegrinding, the reduction box together with the inner forced coolingsystem ensure high efficiency, low voice and long lifespan.

The screw has been designed with reasonable geometric parameter.Corresponding to different raw materials and products, screws withdifferent ratios of lengthdiameter and structures are selected to meetdifferent request of clients. In accordance with different requirementsof raw materials, the heating section Of material barrel has twostructures i. E. Slot section and smooth section. Both screw and barrelare made of alloy steel with excellent properties, which Have advantagesof abrasion resistant, anti-corrosion and high strength. The whole setis of reasonable and standard structure, which ensures Convenientoperation and easy maintenance.
