When we are faced with a wide variety of pipe products, how to choose? The following is the material selection proposed by me based on the analysis of the characteristics of various pipes combined with the characteristics of the project. When we are faced with a variety of pipe products, how to choose? The following are the material selection principles and considerations that I put forward based on the analysis of the characteristics of various pipe materials in combination with the engineering characteristics. Large-caliber water supply pipe

1. Safety and reliability.

This is the most important principle in building PE water supply pipes, because the building PE water supply pipes are pressure pipes. Once the water leaks and bursts, it will cause losses to the building and people’s property. The pipe should be able to withstand vibration and shock, water hammer, thermal expansion and contraction, etc., and withstand the test of time without leaking or bursting.

2. Hygiene.

Obviously, the pipes currently on the market must meet the requirements of the national standard GB/T17219-1998, and they can only be put on the market after being tested by a nationally recognized inspection department. As far as our current hygiene standards are concerned, the PE water supply pipes for buildings are all within the scope of hygiene permits.

3. Energy saving.

Any pipe from raw material extraction and synthesis, cadmium melting, mill rolling, injection and extrusion all consume energy. From a macro point of view, metal pipe consumes more energy than plastic pipe. In the composite process, the steel-plastic composite pipe using the thermal expansion and spraying composite process consumes more energy than metal pipes, and thick-walled pipes consume more energy than thin-walled pipes.

4. Economy.

On the premise of satisfying the use of safe water supply, use the pipes with the least amount of money. While comparing the prices of pipes, it is also necessary to compare the prices of pipe fittings, as well as the construction and installation costs.

5. Sustainable development.

Any kind of pipe can be used by people, and the important reason is that it can be recycled and reused and does not produce new pollution.
