Helical corrugated steel pipes are formed by rolling galvanized steel strips into a specific wave pattern, bending them into a circular shape, and then spiraling them so that the edges interlock, creating a continuous cylindrical structure. Invented in the United States in 1896, these pipes have been in use for over a century and serve as an ideal alternative to concrete pipes and reinforced concrete structures.

Helical corrugated steel pipe features

High compressive strength: 1.5 to 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 pipes

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

Helix corrugated steel pipe applications

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

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

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

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

Agricultural Supplies: field well liner pipes, irrigation canals, siphon tubes, grain storage warehouses
