Anti-Corrosion
3PE Coated Steel Pipe
Three-layer polyethylene coating that combines fusion-bonded epoxy, copolymer adhesive, and a tough outer PE jacket for long-life buried service.
Overview
Built for the application, not just the catalog
The coating is applied in a controlled factory process after surface preparation to Sa 2.5. Thickness is matched to the pipe diameter and project specification, typically ranging from 1.8 mm to 3.7 mm for the total system.
3PE is widely specified for water, gas, and oil pipelines because it performs well across a broad temperature range and resists soil stress, impact, and handling damage.
