Shaft connected with the base of the shaft to appropriate USES heat shrinkable belt (set), the first to deal with well the base joint of the outer wall and the outer wall of shaft uniform preheat to 70 degrees Celsius, and to have been preheated to the outer wall and the outer wall of shaft connection well base along the circumferential direction, sand, attention must be preheated before, sand, sand hair no longer to be nice to have sand wall after preheating, otherwise affect the connection. Finally moved heat-shrinkable sleeve joint center position, remove the isolation membrane, along the circumferential direction of uniform heating in the middle, and the flame is blue, whistle, flame length should be above 750 px, make its full shrinkage respectively at both ends to extension again after heating, heating heat shrinkable sleeve allow heated temperature shall not exceed 250 ℃, after being completely contraction, where heating surface has dimples again. Should reheating again, in order to make the hot melt adhesive overflow.
Hot melt process with roller will heat shrinkable sleeve rolling several times, and put it on rolling fusion, eliminate air bubbles, heating good heat shrinkable sleeve should circumferential uniform contraction, the surface smooth, no wrinkles, no air bubbles and gap, no burning and cracking phenomenon, heat shrinkable sleeve edge layer fully melted overflow.
Heat shrinkable sleeve is buried and aerial steel pipe joint of anticorrosion and thermal insulation pipe insulation repairing designed a hot shrinkage anticorrosive material, can also be used for sealing the pipe flange connection. It is made up of radiation crosslinked polyolefin substrate and special hot melt adhesive sealing compound and into, special hot melt adhesive sealing and polyolefin base material, steel tube surface and solid epoxy coating can form good bonding. Heat-shrinkable sleeve when heating installation, base material at the same time of radial shrinkage, internal compound rubber melt, tightly covered in the mouth, together with the base material outside the pipeline anti-corrosion formed a solid body, excellent wear resistance, corrosion resistance, impact resistance and good uv radiation and light aging performance.
Heat shrinkable sleeve in mid and late ninety s began to used in the industries of petroleum and natural gas long-distance transportation of oil, natural gas steel pipe joint corrosion at the beginning of this century and used a lot in steel tube joint anticorrosive oil, natural gas, city gas pipeline network joint anti-corrosion, heating pipe joint anti-corrosion, water pipe joints corrosion protection and other fields. This paragraph from the steel pipe anticorrosion. Oil and gas pipe corrosion situation of oil and gas transmission pipe anticorrosion heat shrinkable sleeve, oil and gas transmission pipe anticorrosion with heat shrinkable sleeve, heat shrinkable sleeve in oil and gas industry application prospect of five aspects about the application of heat shrinkable sleeve in steel pipe anticorrosion.
