Helix corrugated steel pipes are continuously circular tubes formed by rolling galvanized steel strips into a specific wave pattern, bending them into a spiral shape, and allowing the edges to interlock. Invented in the United States in 1896, they have been in use for over a century and serve as an ideal substitute for concrete pipes and reinforced concrete structures.

Helical corrugated steel pipe features

High compressive strength: 1.5~5 times that of the same diameter cement pipe

Lightweight and easy to transport: weighs 1/5 to 1/10 of the same diameter cement pipe

Construction Fast: Pipe sections (adjustable from 1 to 12 meters), clamp fast connection

Long service life: twice that of concrete pipes, up to 60-100 years

Helical corrugated steel pipe applications

Drainage aspects: Domestic water discharge, industrial wastewater discharge, road culvert drainage

Passageways: Highway-rail animal and human passages, vehicle passages, small open tunnels, and sheltered passages

Protection: Underground communication cables, pipeline protection for gas networks, urban common utility tunnels

Industrial: Coal mine ventilation pipes, coal mine shafts, pile foundation casings, industrial chimneys

Agriculture: Field well casing pipes, irrigation channels, siphon pipes, grain storage warehouses
