Helical corrugated steel pipes are continuously circular tube-shaped bodies formed by rolling galvanized steel strips into a certain wave pattern, bending and tilting them into a spiral shape, and causing the edges of the steel strips to interlock. Helical corrugated 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 strengthIs 1.5 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 FastPipe section length (adjustable from 1 to 12 meters), clamp band quick connection

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

Helical corrugated steel pipe applications
