Application & Features

We succeed in researching the large caliber hollow wall twine pipes production lines on the foundation of abundantly absorbing and digesting technology . The pipes to be produced base on high density polythene (PE) as main material. The rectangle pipes are extruded by the first extruder and then enter into the twine form machine , at the same time , the second extruder spray the rubber strips and then squeeze to reunite it , It outside wall is neat and smooth . Specification is Φ200-Φ3000mm. According to different usage term, the hardness degree of ring is divided into four grades and the Max can reach 16KN/m2. It is suitable for the sour alkali liquid below 10%. This kind of pipes have many extremely excellent characteristics, such as  corrosion resistant light , easy to fix , long life time (50years),etc , It can substitute the pipes made of high energy consumption material (cement , cast iron , porcelain and ceramics , etc). lt is widely used for sewer in superhighway, municipal construction , flats , athletic field, square , mine agriculture , and bridges etc.
