HDPE gas pipe

HDPE gas pipe

Durable and high safety-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

Acid 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.
