Water supply pipe selection principle: safety and reliability are the most important principles, because the building water supply pipe network is under pressure, the pipeline must be well sealed, and the mechanical strength can withstand the design grade pressure. Once the water leaks and burst pipes will cause damage to people's property. The pipe should be able to withstand vibration shock, water hammer, thermal expansion and contraction, etc., and withstand the test of time without leakage or burst; cleanliness mainly refers to whether the raw material inspection of the pipe has passed the inspection of the health and epidemic prevention department, especially the modifier. , auxiliaries, additives, etc. will not cause harm to the human body; economical, on the premise of meeting the functions of safe and hygienic water supply, through technical and economic analysis, the water supply pipes with the most economical investment are selected. When comparing the price of pipes, it is also necessary to compare the prices of pipe fittings, and also compare the construction and installation costs to save construction funds; it is recyclable, a kind of pipe can be highly praised by technicians, and the important reason is that it can be recycled and reused and do not cause environmental pollution. According to research, it has been 5,000 years since the copper water pipes were discovered in the Egyptian pyramids, and the galvanized steel pipes are easily rusted and affect the water quality and have been limited to a large extent until they are eliminated. For plastic pipes, most of the waste can be recycled and reused. Today, when human beings are increasingly concerned about the earth's environment, environmental protection pipes will become people's first choice.
