Product structure in three layers (referred 3PE): the inner layer is coated with a solvent-free two-component epoxy primer in the steel pipe surface, the intermediate layer is excellent in anti-corrosion properties of hot melt adhesive, the outermost layer of the substrate is modified by a special of high-density polyethylene. When using a two-tier structure of heat shrinkable band (called 2PE), then do not epoxy primer. For a variety of pipe corrosion coating: steel bottom, layer polyethylene (2PE), three-layer polyethylene (3PE), three polypropylene (3PP), epoxy powder (FBE), insulation jackets, coal tar enamels, oil and asphalt. The product has excellent hot melt adhesive properties when heated above melting steel body with a solid combination of coating to form a good seal system corrosion, high peel strength, good corrosion resistance, contraction speed, tightness, good waterproof performance , acid, chemical resistance and good mechanical protection performance, service life with the same pipeline, easy on-site construction operation, low labor intensity. Applications: Widely used in underground, underwater, open-air, saline, desert environment of oil, gas and other pipeline projects in the field of municipal construction, while used in petrochemical, city gas pipeline network, heat pipes, electricity, metallurgy, water Steel and other projects in the pipeline fill the mouth, Mending, interface, turn wound antisepsis and drainage, insulation pipeline project PE, PVC pipe joints sealed fixation Model Specifications: HHTS100 / 45/500 HHTS 130/60 / 500 HHTS 155/75/500 HHTS 210/100/500 HHTS 220/100/500 HHTS 270/130/500 HHTS 290/140/550 HHTS 320/150/550 HHTS 350/170/550 HHTS 375/180/550 HHTS 410/200/500 HHTS 440/210/600 HHTS 537/260/600 HHTS 595/280/600 HHTS 700/330/600 HHTS 800/380/600 HHTS 800/380/600 HHTS 2000/800/600
