Good quality PE water supply pipe application fields and precautionsGood quality PE water supply pipe application fields and precautions
1. Urban water supply: PE pipe head has comprehensive advantages such as safety, sanitation and convenient construction, and has become an ideal pipe material for urban water supply.
2. Natural gas and gas transportation: PVC has become the best choice for medium and low-pressure natural gas transportation pipelines due to a series of advantages such as reliable PE connection, stable performance, easy construction, and corrosion resistance.
3. Replacement of cement pipes, cast iron pipes, and steel pipes: For the old pipes laid in the city, cement pipes, cast iron pipes, etc., can be replaced by old pipes. Without extensive excavation, PE pipes can be directly inserted into the old pipes for replacement. , Construction time is short, especially suitable for pipeline selection in the old city.
4. Municipal Trenchless Engineering: At present, with the development of the city, Trenchless technology is being widely used in various constructions, and jacking pipes (pulling pipes, traction pipes) commonly used in trenchless factories are currently more popular. PE pipes, due to their toughness and price advantages, will have greater development in the trenchless field.
5. Sewage treatment: At present, many sewage treatment plants use PE pipes in addition to cement pipes and HDPE double-wall corrugated pipes during construction. In actual construction, PE pipes with the same caliber flow are superior to other pipes, but in complex environments In the construction of turning and crossing, the convenience is more outstanding.
6. Power threading: Due to the superior resistance and insulation performance of PE pipes, plus its own compressive strength and good pulling force, it is currently used in many power threading constructions.

Note for PE water supply products:
1. PE pipes are plastic pipes, which are not easy to store. If they are afraid of the sun, they must be stored in a well-closed warehouse.
2. The pipe foundation of PE pipes is more strict than that of ductile iron pipes.
3. The hydraulic test of PE pipes is difficult to control during the initial pressure test.
4. The price of the main pipe material of PE pipe is relatively cheap, but the price of pipe fittings is relatively high compared with other pipe materials, such as: electric melting pipe fittings. Although PE pipe has certain deficiencies, as a new type of pipe, it has excellent material properties, wide environmental adaptability and good connection and construction performance. PE water supply pipes will be more widely used.
