Pipeline corrosion heat shrink

Pipeline corrosion thermal units heat shrinkable sleeve, shrink sleeve is seamless whole structure, also known as dead heat shrink sleeve, heat shrinkable sleeve closed, pipe heat shrinkable fill muzzle. The middle layer of hot melt adhesive heat-shrinkable sleeve, an outer layer of improvement of radiation cross-linked polyethylene. Heat Shrink Tubing (HHTS) of underground and overhead weld steel pipe corrosion and heat pipe insulation FJC seal and design, heat-shrinkable sleeve is also used for the whole anti-corrosion steel bends. Mainly used for oil and natural gas long-distance pipeline corrosion and thermal insulation at the pipeline weld, heat-shrinkable tubing can also be used for pipe flange joints, lock hoop parts of the seal corrosion. Installation is simple, fast and save time and labor. Heat shrinkable sleeve is made of radiation crosslinked polyolefin composite substrate made of hot melt and specialty seals, special sealing hot melt adhesive and polyethylene base, steel surface and solid epoxy coating can form a good bond (C PE preservative). Heat shrinkable sleeve, the shrink sleeve base layer shrink, glue melting, shrinking close up mouth coated, heat-shrinkable tubing and the original pipeline coatings form a solid, continuous corrosion body. Corrosion resistance, abrasion resistance, impact resistance, UV resistance and aging properties of light. Implementation of the standards:? SY / T0413-2002 and SY / T4054-2003 1. Product Structure Description shrinking casing, the inner layer is coated on the surface of the steel epoxy primer, the middle layer of hot melt adhesive, the outer layer improvement of radiation cross-linked polyethylene. 2. Performance characteristics of heat shrinkable sleeve is seamless whole structure of the casing, the main pipeline with a sub-mending corrosion, valve seals. Product has good adhesive properties acid corrosion, shrink so fast sealing performance, wide range of applications, easy installation, saving time and labor when quick, preheat temperature is low (50 ℃) and so on. 3. Applications range product is suitable for a variety of tube corrosion coating such as: layer polyethylene (2PE), three-layer polyethylene (3PE), powder epoxy (PBE), insulation jackets, coal tar enamel, petroleum pitch. 4. Product after former No. Model Specification Model Specification shrink the inner diameter of the inner diameter of the length of material use shrink diameter 1 HHTS100 / 45/500 100 45 500 φ57 2 HHTS 130/60/500 130 60 500 φ76 / 89 3 HHTS 155/75/500 155 75 500 φ108 / 114 4 HHTS 210/100/500 210 100 500 φ159 5 HHTS 220/100/500 220 100 500 φ168 6 HHTS 270/130/500 270 130 500 φ219 7 HHTS 290/140/550 290 140 550 φ245 8 HHTS 320/150/550 320 150 550 φ273 9 HHTS 350/170/550 350 170 550 φ299 10 HHTS 375/180/550 375 180 550 φ325 11 HHTS 410/200/500 410 200 550 φ351 12 HHTS 440/210/600 440 210 600 φ377 13 HHTS 537/260/600 537 260 600 φ457 14 HHTS 595/280/600 595 280 600 φ529 15 HHTS 700/330/600 700 330 600 φ630 16 HHTS 800/380/600 800 380 600 φ720 17 HHTS ? 1600/800/600 1600 800 600 φ1200 18 HHTS 2000/800/600 2000 800 600 φ1600 Note: according to customer requirements, production of the corresponding product specifications.
