Plastic pipe will have a greater development, PVC pipe fitting material properties will be improved, to avoid the use of heavy metals containing the stabilizer. A variety of new technologies on the new plastic, are constantly promoting the use of. But the stability of plastic pipe and the aging problem is still the worry.
In order to meet the requirements of safe and reliable operation of water supply pipe network, there are two directions of the development of pipe:
One is the selection of new pipes, phasing out restrictions and does not meet the requirements of the development of the old pipe. The development of excellent performance, good corrosion resistance of new pipe, according to the actual requirements, select the appropriate metal or non metal pipe;
The two is to take measures to protect the surface of the pipe, and the inner lining external anticorrosion coating, to ensure the safety of water quality.
