3 Layer Polyethylene Coating (3LPE)
3 layer polyethylene coating provides excellent corrosion protection, based on the use of a fusion bonded epoxy primer with the mechanical protection afforded by high density polyethylene. Suitable for application on water, oil and gas pipelines at service temperatures up to 85°C, 3LPE has an excellent track record.
