PE water supply pipe has a longer service life
Compared with common pipes such as cement pipes, PE water supply pipes have different service lives. Ordinary water pipes, such as iron water pipes, are relatively easy to rust, and polluting chemicals will also be produced if they are not used for a long time. The PE water supply pipe is a plastic pipe, which not only does not rust, but also lasts for a long time.
PE water supply pipe is safer
Traditional ordinary water pipes have a service life of about three or four years. It is easy to cause sewage leakage and groundwater pollution. Part of the groundwater seeps into the sewage pipeline, reducing the concentration of sewage.
However, because the PE water supply pipe is made of high-density polyethylene, it is not easy to break, so it will not leak, and it will not cause any pollution to water resources.
PE water supply pipe is more resistant to high temperature
After the traditional ordinary water pipe leaks, the soil near the water pipe network is easily washed away, causing the foundation of the building to loosen and even the ground to settle, and the use of cast iron pipes is also prone to scale and corrosion inside. However, PE water supply pipes do not have these problems. It even works well above boiling point, which is much better than other pipes.
In the comparison of PE water supply pipe and plastic pipe, we can see that the material of general plastic pipe will become more brittle when it is colder, that is to say, if it encounters a certain external force at this time, it is easy to will break. In this way, there is no guarantee in terms of service life. Although the price is cheaper than PE water supply pipes, the cost of maintenance and replacement is very high.
Of course, the steel pipe has a very strong structural stability when in use, and the lightness is also very high. It is also due to the performance of the steel itself, so it is easy to freeze during use, which greatly affects the use situation.
At the same time, steel is also more expensive than PE water supply pipes in terms of production costs. Therefore, in use, due to the total cost-effective ratio of these properties, PE water supply pipes are generally used frequently.
product description
PE (polyethylene) material is widely used in the field of water supply pipe manufacturing due to its high strength, corrosion resistance and non-toxicity. Because it will not rust, it is an ideal pipe material to replace ordinary iron water supply pipes. PE water supply pipe implements national standards for products: GB/T 13663.1-2017, GB/T 13663.2-2018 "Polyethylene (PE) Pipeline System for Water Supply Part 2: Pipe".
Due to its unique advantages, polyethylene PE pipes are widely used in building water supply, building drainage, buried drainage pipes, building heating, gas pipelines, electrical and telecommunication protection casings, industrial pipes, agricultural pipes, etc. Its main It is used in the fields of urban water supply, urban gas supply and farmland irrigation.
Product advantages
Corrosion resistance
Polyethylene has unique flexibility and excellent scratch resistance
low temperature folding
PE's unique flexibility also makes it effective against subterranean motion and end loads. On the surface, in terms of strength and rigidity, plastic buried pipes are inferior to cement pipes and metal pipes, but from the perspective of practical application, plastic buried pipes belong to "flexible pipes". Under correct design and laying construction, plastic buried pipes are bears the load together with the surrounding soil. Therefore, plastic buried pipes do not need to achieve the same strength and rigidity as "steel pipes" to meet the requirements of mechanical properties in buried use.
At the same time, the pressure relaxation characteristics of polyethylene can effectively consume stress through deformation, and its actual axial stress level is much lower than the theoretical calculation value, and its elongation at break is generally greater than 500%, and the bending radius can be as small as the pipe diameter. 20~25 times, it is a kind of high toughness material, which is very adaptable to the uneven settlement of the foundation. These characteristics make it the best pipeline to resist earthquake, foundation settlement and temperature difference expansion and contraction.
Low temperature resistance
That is to say, after the pressure is determined according to the requirements of preventing rapid crack growth and damage, the long-term life (such as 20 ℃, 50 years) requirements can be satisfied by itself; materials with poor fracture toughness with rapid crack growth will be eliminated. Its long-term strength properties are good or bad. For example, polyvinyl chloride (PVC-U) gas pipes have been basically replaced by polyethylene (PE) gas pipes. The trend of European polyvinyl chloride (PVC-U) water supply pipes being replaced by polyethylene (PE) pipes has become clear.
