HDPE hollowness wall winding pipe extrusion machine

HDPE hollowness wall winding pipe is called Coil pipe. Large caliber winding pipe, double wallwinding pipe, hollowness winding pipe are made of HDPE and form by winding, welding. Because of its unique molding process can produce pipes up to 3 meters in diameter, which is difficult to complete for other production processes. Because of its excellent melt welding performance not only ensures the molding process and product quality, but also provides reliable ways for connecting construction, such as electric fusion welding, heat shrinkable connection and so on, this is also an important reason for rare leakage. It is for this reason HDPE hollowness wall winding pipe has the unique environmental protection function than other pipes. It provides a very effective method for prevention and control of pollution the current people concerned.
