Similar to other corrugated metal pipes, helical corrugated metal pipe has also the corrugation shape. Corrugations add the structural strength and stiffness to culverts. More over, helical corrugated metal pipe has the special corrugation - annular pattern corrugations, which not only make the culverts more strong and stiff, but also reduce the roughness of flow through the pipe.
As a professional company devoted to providing our customers optimal corrugated steel pipe solutions, we accept customization on pipe diameter and wall thickness, either galvanized and asphalt coating or polymer coated steel is ok.
Anticorrosive corrugated steel pipe is the best choice for harsh environment
We can offer anticorrosive corrugated steel pipe that used in harsh environment because of its superior corrosive resistance. Our anticorrosive corrugated steel pipe can be divided into galvanized pipe, aluminized type 2 coating, polymer-laminated coated and asphalt coated corrugated steel pipe.
Galvanized or zinc-coated steel is the standard finish of all corrugated steel pipe and it performs well in low-abrasion conditions. The galvanized corrugated steel pipe can be serviced for 25 years without damage.
Aluminized type 2 coating can offer much more corrosion resistance than galvanized products. It has the characteristics of aluminum of high strength and low cost. The service life can be up to 75 years.
Polymer-laminated coating is the ideal choice for the most aggressive environments. It is a tough, heavy-gauge film that is laminated to both sides of galvanized steel to produce a corrosion and abrasion barrier. Polymer laminate corrugated steel pipe can stand up to high concentrations of acids and alkalis. The service life can be more than 100 years.
Asphalt coating is often coated after fabrication or after installation. It is used to reinforce the pipe in the sites where the three coatings available (galvanized, alt2 and polymer) on steel delivered to pipe fabrication facilities may not be the best match for the site conditions.
