The materials used in the water supply pipeline are selected according to different regions. For example, in the south,PE pipe and PVC pipe are proposed to be time-saving and laborsaving, and maintenance is easy. Besides, in the South,PE and PVC do not exist in the air oxidation and rust. Northern areas to fully consider the cold, or the use of air conditioning copper pipe is good. The water pipes used at ordinary times are made of PE material. There are many brands on the market at present, such as Rifeng, Hengxing Pipe Company and Weixing. Generally should be air conditioning copper pipe is the best! At present, many ppr pipes are all copper jack. Because copper itself can play a role in improving water quality! Can keep the water will not be polluted by the environment! The common outdoor water supply pipes are spit-and-plug type water supply and drainage cast iron pipe, welded pipe, galvanized pipe, self-stressed reinforced concrete pipe and so on.
pe supply pipe: It has high bearing capacity, strong corrosion resistance, convenient socket, convenient for engineering construction. The inner cavity of large and medium-sized water supply equipment can be made from inside the factory. Cast iron pipe can be selected according to the pressure of the conveying equipment, cast iron pipe can be divided into air conditioning pipe, medium shrink pipe and low voltage pipe three levels, in which the air conditioning pipe pressure is 1.0MPa; The middle tube is 0.75MPa.
Assembly preparation in advance → prefabricated components → pipeline construction → pipeline pressure test → pipeline flushing, disinfection and sterilization → trench excavation backfill. Check and verify the trench excavation center line and elevation according to the requirements of the design drawing, release the pipeline center line and elevation calculation line, and the gutter must meet the installation requirements.

There are two ways to lay pe water supply pipeline:
1, clear match. 2, buried in the dark. The advantage of open laying is convenient maintenance, but it has a certain impact on the overall beauty. The advantage of hidden laying is that the overall hidden open, good appearance, if the pipeline leakage, maintenance is relatively difficult, only need to do the corresponding pressure test before hidden, pay attention to civilized construction in the construction process, can avoid tragedy, general engineering projects mainly use hidden laying
