Heat shrinkable sleeve

Shrink sleeve Shrink sleeve TS series is buried and overhead weld steel pipe corrosion and heat pipe insulation mending and design can also be used for pipe flange joints, lock hoop parts of the seal corrosion. It 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. TS shrinking sets in the heating installation, the radial contraction of the substrate in the same time, internal composite layer melted, tightly covered in the mending, together with the substrate into a solid shape in the pipeline corrosion body with excellent The wear resistance, corrosion resistance, impact resistance and good UV resistance and aging properties of light.
