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 causing 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 concrete pipes and reinforced concrete structures.

Helical corrugated steel pipe features

High compressive strength: up to 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 concrete pipe

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

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, pipeline protection for gas networks, urban common ducts

Industrial: Coal mine ventilation pipes, mine shafts, pile shell, industrial chimneys

Agricultural supplies: farm well casing pipes, irrigation canals, siphon pipes, grain silos
