PPR, PE, PVC, HDPE pipe how to distinguish?(2)

PE pipe

PE PE is polyethylene plastic, is a kind of production by a variety of processes, with a variety of structures and characteristics and a variety of uses of series of resin.

PE pipe has medium density polyethylene pipe and high density polyethylene pipe, according to the wall thickness into SDR11 and SDR17.6 series. The former is suitable for transporting gaseous artificial gas, natural gas and liquefied petroleum gas, while the latter is mainly used for transporting natural gas.

Compared with steel pipe, the construction process is simple, has a certain flexibility, more importantly is not used as anti-corrosion treatment, will save a lot of procedures. The disadvantage is that the equipment is not as good as the steel pipe, the construction of special attention to the safe spacing of heat heating, and can not be exposed to the sun in the air, and sensitive to chemicals, to prevent damage caused by the leakage of sewage pipes.

The characteristics of PE pipe

1, environmental health: no scaling, no bacteria, solve the secondary pollution of drinking water.

2, good flexibility: good flexibility, high impact strength, high elongation at break, very strong adaptability to the uneven settlement of the pipe foundation, excellent seismic performance.

3, simple construction: the construction process is simple, the system cost is low, the maintenance cost is less, and the project cost is greatly reduced.

4, long service life: under normal conditions, the service life is up to 50 years.

5, convenient transportation: light weight, convenient transportation and installation.

6, circulation rate is good: excellent wear resistance, wall friction coefficient is very low, medium through the ability to improve.

7, corrosion resistance: inert materials, can withstand a variety of chemical media erosion, no electrochemical corrosion.

8. Reliable interface: hot melt docking and hot melt insertion technology makes the interface strength higher than the pipe body, and the interface is safe and reliable.
