Water supply pipe, a kind of green, energy saving, environmental protection pipe, no rust, no scaling, no shrinkage, small fluid resistance, can effectively reduce the energy consumption of water supply, improve the water supply point, is an ideal pipe network with pipeline. Water is the source of life and the basis for the survival and development of human civilization. Water crisis has become the focus of common concern of all mankind in the world.

At present, China's increasingly serious shortage of water resources and water pollution, not only troubled the national economy and people's livelihood, and has become an important factor restricting the sustainable development of social economy. The construction industry is a pillar industry in our country. To do a good job in the design, construction and maintenance of building water supply and drainage system is a specific means to realize water saving, energy saving and water pollution prevention, and it is also an urgent need to do a good job in energy saving and emission reduction and environmental protection.

Classification of water supply pipe

The water supply pipe is divided into metal pipe, composite pipe and plastic pipe. Metal pipes are mainly divided into copper pipes and stainless steel pipes. Metal pipes are safe, hygienic, durable and many other characteristics. They are the most ideal water pipes for home improvement tools. Composite pipes typically represent aluminum-plastic pipes, but they have been gradually eliminated due to their thermal expansion and contraction problems.

The most commonly used plastic pipe is PPR water pipe, which is safe, non-toxic, easy to install, low price and many other reasons, making it the most commonly used water pipe for home improvement. However, due to environmental hormones and other issues, more and more people are beginning to use metal pipes or ppr lined metal pipes as water supply pipes.

The performance indicators of water supply pipes are relatively strict, especially for drinking water. The pipes need to be non-toxic and non-radiation, cannot contain harmful substances such as heavy metals, have good corrosion resistance, and have a long service life.

Product Introduction
PE pipes are produced by extrusion plasticization using high-density polyethylene, which gradually replaces traditional reinforced concrete pipes and metal pipes.
Product Features
1. Good sanitary performance: PE pipe processing does not add heavy metal salt, the material is non-toxic, no scaling layer, no bacteria, a good solution to the secondary pollution of urban drinking water
2. Good low-temperature impact resistance: The low-temperature embrittlement temperature of polyethylene is extremely low, and it can be used safely in the temperature range of 0 ℃-40 ℃.
3, good stress cracking resistance: with low notch sensitivity, high shear strength and excellent scratch resistance, environmental stress cracking resistance is also very prominent.
4, good chemical resistance: resistance to a variety of chemical medium corrosion, will not rot, rust or electrochemical corrosion phenomenon, will not promote the growth of algae, bacteria or fungi.
5, aging resistance, long service life: black pipes can be stored or used outdoors in the open air, and will not be damaged by ultraviolet radiation.
6. Good wear resistance: The comparative test of wear resistance between PE pipe and steel pipe shows that the wear resistance of PE pipe is 4 times that of steel pipe, which has longer service life and better economy.
7, good flexibility: easy to bend, the project can be bypassed by changing the way of pipe direction, can reduce the amount of pipe fittings and reduce installation costs.
8. Low water flow resistance: It has a smooth inner surface, and its Manning coefficient is 0.009, which has higher conveying capacity, and also reduces the pressure loss of the pipeline and the energy consumption of water delivery.
9, easy to handle: lighter than concrete pipes, galvanized pipes and steel pipes, easy to handle and install, lower manpower and equipment requirements, means that the installation cost of the project is greatly reduced.
10. A variety of new construction methods: with a variety of construction technologies, in addition to the traditional excavation methods for construction, you can also use a variety of new non-excavation technologies such as pipe jacking, directional drilling, lining, pipe cracking and other methods for construction.
Application areas
1, urban water supply; with safety, health, convenient construction and other comprehensive advantages, has become the ideal pipe for urban water supply.
2. Food and chemical industry; it has unique chemical corrosion resistance, can be used for the transportation or discharge of various acid, alkali and salt solutions, with long service life, low cost and maintenance cost.
3, ore, mud transportation; wear resistance is 4 times of steel pipe, can be widely used in conveying ore, power plant fly ash, river dredging mud.
4, replacement of cement pipes, cast iron pipes and steel pipes; For the transformation of old pipes such as cement pipes and cast iron pipes originally laid in the city, PE pipes can be directly inserted into the old pipes for replacement without large-scale excavation. The project cost is low and the construction time is short. It is especially suitable for pipeline transformation in old urban areas.
5, landscaping pipe network; landscaping needs a large number of water pipelines, PE pipeline cost is low, it is worth promoting.
6. Other applications: PE pipeline can also be widely used in other fields, such as electric power, communication sheath, farmland irrigation, siphon drainage, landfill, geothermal air conditioning, deep sea aquaculture, buried fire pipeline, etc.
