Helical 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 are an ideal substitute for concrete pipes and reinforced concrete structures.

Helical corrugated steel pipe features

High compressive strength: 1.5 to 5 times that of the same diameter concrete pipes

Lightweight and easy to transport: 1/5 to 1/10 the weight of cement pipes of the same diameter.

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

Long service life: Twice as long as cement pipes, up to 60-100 years

Helix corrugated steel pipe applications

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

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

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

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

Agricultural Supplies: farm well casing, irrigation canals, siphon tubes, grain storage warehouses
