Helical corrugated steel pipes are continuously circular tube-shaped bodies 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: up to 1.5 to 5 times that of cement pipes of the same diameter

Lightweight and easy to transport: up to 1/5 to 1/10 the weight of the same diameter concrete pipe

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

Long service life: twice as long as concrete pipes, up to 60-100 years

Helical corrugated steel pipe applications

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

Passage options: Highway and railway crossings, animal and human passages, vehicle crossings, 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 shells, industrial chimneys

Agricultural supplies: field well wall pipes, canal irrigation, siphon pipes, grain storage warehouses
