Polymer coated corrugated steel pipes (CSP) are galvanized pipe that have had a laminate film applied over it. Polymer coating provides excellent adhesion to the base steel and extended corrosion and abrasion resistance.
Recent testing indicates polymer coated CSP can withstand abrasion level three conditions. Since polymer is a barrier coating, it exhibits uniformly predictable durability performance within defined environmental ranges. Over the last 40 years, the performance of polymer CSP has been monitored by Corrpro and found to have essentially no deterioration despite installation in some extreme environments. Polymer coated pipe operating within these ranges can achieve a 100-year service life.
