3 Application & Features
We succeed in researching the large caliber hollow wall twine pipes production lines on the foundation of abundantly absorbing and digesting European technology . The pipes we 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 Φ400-Φ2500mm. 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 character- istics, 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 superhigh-
way, municipal construction , flats , athetic field, square , mine agricltrue , and bridges etc.
