Ten advantages of pe water supply pipe
PE water supply pipe is a flexible pipe made of high-density polyethylene (HDPE) as raw material, which is extruded and vacuum-formed, and has smooth inner and outer walls. It is mainly used for the construction of urban water pipe networks. As a tap water pipe network construction requirements are very strict, it is checked by various departments, there must be advantages that other pipelines do not have!
1. The pe tube connection is very reliable
The PE water supply piping systems are connected by hot-melt socket and hot-melt butt joints. The strength of the joint is higher than the strength of the PE water supply pipe itself; the polyethylene pipe and other pipes are connected by flanges, which is convenient and quick.
2. Good impact resistance at low temperature
The low-temperature embrittlement temperature of polyethylene is extremely low, and it can be used safely in the temperature range of -60℃-60℃. During winter construction, because the polyethylene pipe has good impact resistance, it will not be embrittled.
3. Has strong resistance to stress cracking
It has low notch sensitivity, high shear strength, and excellent scratch resistance, and its resistance to environmental stress cracking is also very outstanding.
4. Good chemical resistance
PE water supply pipe can withstand the corrosion of a variety of chemical media, and the chemical substances in the soil will not cause any degradation to PE water supply pipe.
5. Anti-aging and long service life
Polyethylene pipes containing 2-2.5% evenly distributed carbon black can be stored or used outdoors for 50 years, and the polyethylene pipes will not be damaged by ultraviolet radiation.
6. Good wear resistance
The comparison test of the wear resistance of PE water supply pipes and steel pipes shows that the wear resistance of PE water supply pipes is 4 times that of steel pipes. In the field of mud transportation, compared with steel pipes, PE water supply pipes have better wear resistance, which means The PE water supply pipe has a longer service life and better economy.
7. Has the good winding ability
The flexibility of the PE water supply pipe makes it easy to bend. In engineering, obstacles can be bypassed by changing the direction of the PE water supply pipe. In many cases, the flexibility of the PE water supply pipe can reduce the amount of polyethylene water delivery pipes for agricultural irrigation and reduce installation costs.
8. Small resistance to water flow
The PE water supply pipe has a smooth inner surface, and the PE water supply pipe has a Manning coefficient of 0.009. The smooth surface and non-adhesive characteristics of the PE water supply pipe ensure that the pipe has a higher transmission capacity than traditional pipes, and also reduces the agricultural irrigation polyethylene transmission. The pressure loss of water pipes and the energy consumption of water delivery.
9. Easy to carry
PE water supply pipes are lighter than concrete pipes, galvanized pipes, and steel pipes. It is easy to handle and install and has lower manpower and equipment requirements, which means that the installation cost of polyethylene pipes is greatly reduced.
10. Various construction methods
PE water supply pipeline has a variety of construction technologies. In addition to traditional excavation methods, it can also use a variety of new non-excavation technologies such as pipe jacking, directional drilling, lining pipes, and split pipes. Some sites that do not allow excavation are the only option!
