HDPE gas pipe
HDPE gas pipe
Durable and high safety-mainly used in urban gas engineering
Safe use for more than 50 years
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.
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.
PE pipe can be used for electric fusion or hot-melt connection. Its connection is complete, tight and will never leak.
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
PE pipe can withstand organic solvents such as hydrogen peroxide and methyl gasoline at normal temperature, and PE pipe will not corrode.
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.
