3 LPE COATING ACC. TO DIN 30670
Layer 1: This is a layer is of fusion bonded epoxy used for good corrosion protection.
Layer 2: Second layer is the copolymer adhesive and has good chemical bonding with both layesr of fusion bonded epoxy (FBE) and the top layer polyethylene.
Layer 3: This top layer is consists of polyethylene to bond well with each other

Third layer of polyethylene coated pipes are the preferred choice for transmission of oil and gas around the world. It can withstand varying temperatures and environments ranging from desert drylands to deep underwater regions. 3LPE coated steel pipes are used for transportation of oil and gas, drinking water and other fluids. 3LPE coated pipes can be used in the high temperatures as high as 60 to 80°c.
