Description: New type stable PPR pipe production line is a new generation pipe production line developed by adopting updated German technology, it overcomes the defects of common PPR pipes such as high expansion coefficient, bad anti tardily variation, very easy to deform. Inner layer of pipe products is the common pipe extruded, after it is coated with aluminum foil, then coated by a PPR out layer, the foil layer is sticking on plastic layer with hot-melt glue. Production is made up of PPR inner layer molding unit, aluminum foil molding, glue coating unit and out PPR extrusion molding unit etc. The products have the characteristic such as anti high temperature, easy joining and small thermal expansion coefficient, powerful anti press intensity, anti ultraviolet radiation, good anti strike at low temperature, which expand the application range for common PPR pipe. This line can't only produce stable PPR pipe, but also the common pipe.
