UPVC/CPVC double-wall corrugated pipe is a specially structured pipe with hollow ring and joist steel section. It owns novel structural design, high-rigidity ring, good endurance of external load and excellent mechanical property. It is characterized by light weight, high strength and good toughness; heat-resistant modification has substantially increased its Vicat softening temperature.

Electrical and communications embedded pipes of expressway;

Water delivery and drainage pipelines of agricultural irrigation and water conservancy;

Fluid delivery pipeline in chemical and mining industry;

Protection pipe for high and low-voltage cable, post and telecommunications cable.

Good flexibility, resistance to high temperature, rare rupture and aging;

It adopts flaring spigot and socket, high-temperature rubber ring for the purpose of tightness and waterproof. Therefore, it adapts to thermal expansion and cold contraction, owns convenient connection, good tightness, no leakage, short construction cycle and low cost.

Smooth inner wall has a small frictional resistance, so cables go through the pipe without damages.

Light weight and high performance cost ratio; it saves 30~50% materials compared with other pipes.

Unique structure, high strength and excellent compression resistance;

Corrosion resistance, no leakage, environmental protection and no pollution of the environment;

Its service life is over 50 years in case of buried application.
