            High density polyethylene (HDPE) winding structure wall pipe is made of high density polyethylene (HDPE) resin as the main raw material, hot-wound poplar-shaped process, polypropylene (PP) single-wall bellows as the support structure to make a special structure with high external pressure resistance. Wall tube, carat tube products can be divided into three series: PR, OP, SQ and VW.
            The carat tube equipment is a product of environmental protection and safety. Clark pipe continuous equipment has many advantages, such as light weight, strong bearing capacity, high quality interface, long life, corrosion resistance, easy construction and so on.

            Clark pipe produced by Clark pipe equipment also has many advantages, the quality of Clark pipe is lighter, and the overall flexibility is relatively good, is currently the most widely used buried sewage drainage pipe.
            Because of the advantages of the Clark tube, it is widely used in municipal engineering, road public works and industry. For example, Clark pipes are used for municipal underground drainage, sewage discharge, rainwater collection, water conveyance, ventilation and so on; and then for drainage pipes of golf courses, football fields, highways and railways; because the material of Clark pipes is polypropylene and polyethylene, their acid and alkali resistance and corrosion resistance are relatively strong, so they are widely used in nuclear power plants, steel plants. Petrochemical, docks, stations and other fields.
