Helical corrugated steel pipes are continuously formed circular tubes made 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, these pipes have been in use for over a century and are an ideal substitute for cement 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: 1/5 to 1/10 the weight of the same diameter cement pipe

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

Helical corrugated steel pipe applications

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

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

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

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

Agriculture: Farm well casing pipes, canal irrigation, siphon pipes, grain storage warehouses
