Helical corrugated steel pipes are continuously circular tubes formed by rolling galvanized steel strips into a specific wave pattern, bending them into a spiral shape, and allowing 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 ribbed 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 cement pipe.
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
