Helical corrugated steel pipes are continuously shaped circular tubes formed by rolling galvanized steel strips into a specific wave pattern, bending them into a circular shape, and then spiraling them to interlock the edges of the strips. Invented in the United States in 1896, they have been in use for over a century and are 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 only 1/5 to 1/10 of the same diameter concrete pipe.

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

Long lifespan: twice as long as concrete pipes, up to 60-100 years

Helix corrugated steel pipe applications

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

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

Protection: Underground Communication Cables, Gas Pipeline Protection Ducts, Urban Common Tunnels

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

Agriculture: Field well casing pipes, canal irrigation, siphon tubes, grain storage silos
