→APPLICATION & FEATURES :

  


      We succeed in researching the large caliber hollow wall twine pipes extrusion line on the foundation of abrndantly absorbing and digesting Eurpean technology. And acquire many items of national patents. 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's outsidd wal is neat and smooth. Specification is ф400-ф1500mm. According to different usage term, the hardness degree of ring is divided into fourgrades and the Max can reach 16KN/㎡. It is suitable for the sour alkali liqued below 10%. This kind of pipes have many extremely Excellent characteristics, such as , corrosion resistant light , easy to fix, long life time (50 years), etc, It can substitute the pipes made of high energy consumption material(cement, cast iron, porcelain and ceramics, etc)It is widely used for sewer in superhighway, municipal construction, flats, athetic filed, square, mine agricltrue, and bridges etc.
