| 3 Layer Polyethylene Coating (3LPE) | | | Operating Conditions
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. | | | | Application and Standards
Our Coatings applies 3LPE in accordance with recognized international standards such as CSA Z245.21., DIN 30670 and AS1518, as well as many customer specifications. Where required Coatings can provide details of in house specifications for this product, or help develop a project- specific coating specification. | | | Typical Properties
