3PE Coated Spiral Pipe
Three-layer polyethylene (3PE/3LPE) combines fusion-bonded epoxy, adhesive and polyethylene into one coating system that protects buried pipelines for 30+ years.

High humidity and saline soil accelerate bare-pipe corrosion dramatically. 3PE is the default specification for Indonesian municipal water and gas pipeline projects — specified to GB/T 23257 and DIN 30670.
