The water pipes all use to plate zinc steel pipe for long time and plate the zinc steel pipe uses over a long period of time so apt to rust, and stir up a germ, threaten people's health. The from here a series of and new water pipe birth desire replaces to plate zinc steel pipe and mainly have: Copper tube, stainless steel tube, plastics compound steel pipe, aluminum plastics compound tube, the PP-R take care of and the PEX take care of etc., among them again reunite steel pipe by plastics applied the most wide. Should produce a demand, this topic designs a set of control system, applied programmable controller, touch to hold an etc.' s technique to combine machine system completion to the water pipe inside wall of tidy up. Inside wall steel pipe after tidy up again use to gather the ethylene as lining material to melt to revolve to model a craft to process with the heat but become, make lining material and metals steel intertexture hot to merge into an integral whole, firmly gather knot in wall inside the piping after cool off, so then can batch quantity produce plastics compound steel pipe.
This topic research success, can consumedly raise the yield of the plastics compound steel pipe, economy labor force, exaltation produce efficiency, with satisfy the need of market, let more and more people use more high-quality running water.
