HDPE gas pipe is durable and safe, mainly used in urban gas engineering.
◎ Long life
Safe use for more than 50 years.
◎ Flexibility
The PE pipe has an elongation at break of more than 500%. It will not rupture under different subsurface changes such as ground subsidence and earthquakes, and has high safety. Bending radius (R≥15D), no need for elbow joints, which is convenient for construction.
◎ Cold resistance
The linear expansion coefficient of PE pipe is 1.5X10-4mm / mm ° C, and its length is almost unaffected by temperature changes. No physical change occurs even at -80 ° C. It is especially suitable for severe cold regions.
◎ Weldability
PE pipe can be used for electric fusion or hot-melt connection. Its connection is complete, tight and will never leak.
◎ Corrosion resistance
Immerse in hydrochloric acid at room temperature. In sulfuric acid (≤70%), nitric acid (≤25%), phosphoric acid, hydrofluoric acid, complex acid (≤10%) and other solutions, PE pipes are not affected.
◎ Alkali and inorganic salts
PE pipe is immersed in various lye, inorganic salt and seawater at 60 ℃, PE pipe will not corrode.
◎ Organic matter
PE pipe can withstand organic solvents such as hydrogen peroxide and methyl gasoline at normal temperature, and PE pipe will not corrode.
◎ Workability
PE pipe is light weight (only 1/7 of steel pipe) and has good flexibility. De16-De75 pipe can be wound for easy transportation and construction.
