the last 30 years such that steel chemistry has allowed the development of high strength steels . used for steel pipe asphalt and single and two layer polyethylene coatings have been
3-Layer Coating The 3-Layer Manufacturing Process 3-Layer Coating is the generic term for a pipe outer coating comprised of FBE base or primer coat, an extruded co-polymer adhesive intermediate layer and an extruded polyethylene top coat, as described by System B1 of the Canadian Specification Z245.21-02. 3LPE Coated Pipes 3 Layer Polyethylene Pipe Coating Process3LPE or as referred to as 3-Layer Polyethylene is a multilayer coating applied on steel pipes that is composed of three functional components:1. A high performance Fusion Bonded Epoxy (FBE) primer, 2. a copolymer adhesive and 3. an outer layer of polyethylene.
3LPE Coated Pipes consist of 3 layers for pipeline coating. Layer 1 consists of Fusion Bonded Epoxy. This later provides protection against corrosion and is fusion bonded with the blasted steel surface. Layer 2 is a copolymer adhesive which has excellent chemical bonding to the inner layer and the top layer of polyethylene. 3PE Coated Steel Pipe3LPE Coating pipes3PE Coated Steel Pipe. 3PE, we also called 3LPE. 3PE coated steel pipe is one kind of coating method which used in carbon steel pipe. No matter it is seamless steel pipe of welded steel pipe, stainless steel pipe or alloy steel pipe, nickel alloy pipes or CRA clad or lined pipe, it can do 3PE coating for the pipes.

Anti-Corrosion Coating Pipe. Anti-corrosion coating pipe refers to 3-layer structure polyethylene coating (MAPEC) external anti-corrosion steel pipe, which is a kind of anti-corrosion pipe commonly used in China.The three-layer polyethylene (3PE) anti-corrosion coating has been widely used in the petroleum pipeline industry for its good corrosion Extruded three-layer polyethylene coating on steel pipes cooling the coating and dressing the pipe ends. An extruded polyethylene coating has higher mechanical properties in comparison with cold applied polyethylene tape coating. Anticor- rosive coatings made of three-layer PE/PP are characterized by:high mechanical strength, high adherence of the coating to the pipe,
Today, the three-layer plastic coating is standard practice for steel line pipe. For the first two layers, powder is electrostatically applied to the preheated pipe surface, and the actual plastic coating is then extruded onto the second layer as a seamless tube. The first layer consists of epoxy resin and serves as a primer on the steel surface. Minimum thickness of 3 layer polyethylene coating A519 Mar 18, 2018 · The minimum coating thickness shall be 0.7mm greater where coatings will be subjected to particularly high mechanical stress. Along any 1 m length of pipe, the coating thickness may be up to 10% less than the minimum required, provided the thinner area does not cover more than 5 cm 2. ISO 21809-1 Petroleum and natural gas industries External coating
