3 Layer polyethylene coating is the perferred method of corrosion protective coating applied on steel pipes used in oil & gas applications. Engineers and end users the world over specify 3LPE coating for its versatility & flexibility for its use in varied environment from hot & sandy desert soil of the Gulf to harsh frosty sea beds in the Artic region. 3 Layer PE Steel Pipe Anti-Corrosion Processing Line3 Layer PE Steel Pipe Anti-Corrosion Coating Machinery. 3LPE coating line is to make anti-corrosion of kinds of steel pipes, such as single layer FBE, double layer FBE, double layer PE, double layer PP and 3PE. Outer protective layer of coated pipe has a high
3LPE is a coating system consisting of an inner layer of Fusion Bonded Epoxy, copolymer adhesive layer and outer layer of Polyethylene. Inner layer provide corrosion protection and flexibility while outer layer of Polyethylene provide impact and abrasion protection. Between the inner and outer layer are tape. 3-Layer Coatings:Technical Details3-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. Application of 3-layer coatings follow the same typical process. 3LPE Coated Pipes Manufacturer, 3 Layer Polyethylene Tubos India is one of the large manufacturers for high quality 3LPE pipes. 3 layer polyethylene coating(3LPE) is a multilayer coating composed of three functional components such as:Grafted copolymer adhesive, FBE primer and an outer layer of polyethylene to provide great corrosion protection and mechanical protection for gas & oil pipelines at operating temperatures upto 80 degree
The external and internal 3LPE coating and lining is bonded firmly to the mild steel pipe surface and the mean adhesion strength is 125 kg/cm² (ASTM D 4541). Long Working Life :Pipe has constant performance characteristics through out the life span. Service life of more than 75 years. 3LPP Pipe Coating 3 Layer Polypropylene Coating Pipeline Essentially a multilayer coating, 3-Layer Polypropylene or also known as 3LPP Pipe Coating comprises of three functional components. 3LPP Coating Steel Pipe Process The initial layer of a 3 Layer Polypropylene Coating includes the application of a high-performance Fusion Bonded Epoxy primer or in short an FBE primer via fusion bonding. Specification For 3lpe And 3lpp Coating Of Line Pipe Hpcl3-Layer Polyethylene Coatings (3LPE) can be used in operating conditions of up to 80ºC, making them suitable in most steel pipe applications from water to gas transfer. However, for pipelines with operating temperatures in excess of 80ºC, polypropylene and the associated high temperature FBE and co-polymer adhesives are required 3LPP.
3LPE anti-corrosion steel pipe base material including seamless steel pipe, ERW pipe, SSAW pipe and LSAW pipe. Three-layer structure of polyethylene (3PE) anti-corrosion coating with good corrosion resistance, mechanical properties and water vapor permeability, etc., it has been widely used in the oil pipeline industry.
