The products have the characteristics such as anti high temperature, easy joining, small thermal expansion coefficient(0.4mm/m·&#***1;, quarter of that for common pipe), powerful anti press intensity, anti ultraviolet radiation, good anti strike at low temperature, which expand the application range for common PP-R pipe. The production lines are used to make the stabilized PPR pipes. This kind of pipes are PPR pipes wrapped by an aluminum foil, which makes the pipes having an excellent high creep resistance. And the thermo-expansion factor of the pipes is only 1/3 of the ordinary PPR pipes. Therefore, the pipes can be applied to inclement and changeable environment. v Perfect aluminum foil wrapping process, v Perfect aluminum foil over-lap adhere technology, v High performance PPR extruder, v High operating reliability, yielding high quality pipes continuously, v Precision aluminum foil wrapping tools based on know-how, v Different aluminum foils can be used, v Automatic control by touch-screen, v NC control system based on PLC control, v Can be extended to produce PE or PPR pipes.
