pe drainage pipe characteristics

Corrosion resistance

Polyethylene is a non-malleable raw material that is resistant to a wide variety of chemical corrosion except for a small amount of oxidizing agents, and does not easily grow germs. We all know that seamless steel pipe, cast iron drainage pipe is replaced by plastic hose not only because of the plastic pipe than its low energy consumption of water, low energy consumption in daily life, lighter weight, small friction resistance of flowing water, installation is simple and fast, low project cost, long life, with heat insulation and heat preservation, etc., but also because of the corrosion resistance of plastic hose, not easy to grow microbial strains of bacteria and other properties better than the seamless steel pipe and cast iron drainage pipe.

Flexibility

Polyethylene has unique flexibility and high quality scratch resistance. The flexibility of polyethylene piping systems has great safety engineering value. The flexibility of polyethylene is an important characteristic that greatly increases the value of this raw material for use in piping projects. The excellent flexibility enables polyethylene pipes to be coiled and supplied in very long lengths, preventing many connectors and pipes.

Cold Resistance

Polyethylene has very outstanding cold resistance. pe pipe has an ultra-low temperature embrittlement point of -70℃, which is better than other pipes. Polyethylene (PVC-U) pipe in the winter suburban engineering construction is very easy to brittle crack, in China's Beijing city to lay polyethylene (PVC-U) buried drainage pipe demonstration site project summed up a work experience is that the temperature is below zero degrees is also unsuitable for the laying of polyethylene (PVC-U) pipeline.

Impact Toughness

Polyethylene has excellent fast cracking to improve impact toughness. Occurrence of rapid cracking bad, cracks to 100 ~ 45m / s speed quickly expand 500 meters to 100 kilometers, long-distance piping damage, the scale of the leakage of security accidents, followed by the ignition of explosions (gas transmission) and flooding (through the water) security accidents.
