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, they have been in use for over a century and are an ideal substitute for concrete pipes and reinforced concrete structures.

Features of Spiral Woven Steel Pipe

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 concrete pipe

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-waved steel pipe applications

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

Passageways: Road and rail animal crossings, vehicle passages, small cut-and-cover tunnels, and sheltered passages

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

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