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 pipe

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

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

Helix corrugated steel pipe applications

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

Passage options: 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: farm well casing, canal irrigation, siphon pipe, grain storage warehouse
