Helical corrugated steel pipes are continuous circular tube structures formed by bending and helically winding galvanized steel strips, which are rolled into a specific wave pattern and then interlock at the edges. 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 cement pipe

Lightweight and easy to transport: 1/5 to 1/10 the weight of standard diameter cement pipes

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

Helical corrugated steel pipe applications

Drainage: 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 common utility tunnels

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

Agriculture: Field well casing, canal irrigation, siphon pipe, grain silo
