Helical corrugated steel pipes are continuous circular tubes formed by rolling galvanized steel strips into a specific wave pattern, bending and tilting them into a spiral shape, causing the edges of the strips to interlock. Helical corrugated steel pipes are manufactured in the United States.Invented in 1896, it has been in use for over a century and is an ideal substitute for cement pipes and reinforced concrete structures.
Helical corrugated steel pipe features
High compressive strength1.5 to 5 times the diameter of the same-size cement pipe
Lightweight and easy to transportIs 1/5 to 1/10 the weight of the same diameter concrete pipe.
Construction FastPipe section length (adjustable from 1 to 12 meters), clamp fast connection
Long service lifeTwice the life of concrete pipes, up to 60-100 years.
Helical corrugated steel pipe applications
Drainage aspectDomestic water discharge, industrial wastewater discharge, road culvert drainage
Channel mattersHighway-rail animal and human crossings, vehicle crossings, small open tunnels, sheltered passages
Protection AspectUnderground communication cables, pipeline protection for gas networks, urban common trench
Industrial sectorCoal mine ventilation pipes, coal mine shafts, pile foundation shells, industrial chimneys
Agricultural sectorField well casing, canal irrigation, siphon pipe, grain silo
