3LPE Coated Seamless Pipe 3lpe External Coating manufacturer. Stockist of 3 Layer Polyethylene Internal Coating Pipes. MSL, JSL and ISMT Coated Welded Pipe supplier 3-Layer Polyethylene is a multilayer coating that is as commercially recognized by its shortened name - 3LPE. As the name suggests, this coating constitutes of three functional components. First - A high performance FBE primer or Fusion Bonded Epoxy primer. Second is a copolymer adhesive and the final constituent is an outer layer of polyethylene. The three coating layers in 3-LPE coated pipe Layer 1: Usually the corrosion protective layer. This layer is of combination bonded epoxy which offers exceptionally good corrosion protection. The fusion reinforced epoxy contains a very great holding with the blasted steel surface. Layer 2: This layer is the copolymer adhesive. The copolymer adhesive could be a maleic anhydride united polyethylene compound. This material has great chemical holding to the fusion reinforced epoxy and the beat layer polyethylene. Layer 3: This layer is for physical protection and comprises polyethylene. Since the copolymer adhesive and polyethylene are comparable, they bond well with each other Standards and Specifications : DIN 30670 / CSA Z245.21 / ISO 21809-1 Size range : 25 mm to 3000 mm Lengths limit : up to 12m Pipes : ASTM A106 Grade B, API 5L Grade B / API 5L X42, X46, X52, X60, X70, IS 3589 3LPE Coating Pipe suppliers, 3LPE Coating Mild Steel Pipe, Coating Steel 3lpe pipe according to DIN30670, api 5l gr.b 3lpe coating seamless steel pipe price, 3LPE coated line pipe supplier
