Spiral-welded steel pipes are continuous circular tubes formed by rolling galvanized steel strips into a specific wave pattern, bending them into a helical shape, and allowing the edges to interlock. Spiral-welded steel pipes are made 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-sized cement pipe

Lightweight and easy to transportIs 1/5 to 1/10 the weight of pipes with the same diameter.

Construction Fast: Pipe section length (adjustable from 1 to 12 meters), clamp fast connection

Long service lifeTwice the strength of concrete pipes, up to 60-100 years.

Helical corrugated steel pipe applications

Drainage aspectDomestic water discharge, industrial wastewater discharge, road culvert drainage

Channel aspectsHighway and railway animal crossings, vehicle crossings, small cut-and-cover tunnels, and sheltered passages

Protection AspectUnderground communication cables, pipeline protection for gas networks, urban common utility tunnels

Industrial sectorCoal mine ventilation pipes, coal mine shafts, pile foundation casings, industrial chimneys

Agricultural sectorField well casing, canal irrigation, siphon tube, grain storage silo
