The heat shrinkable sleeve is made of a radiation crosslinked polyolefin substrate and a special sealed hot melt adhesive. The special sealed hot melt adhesive can form a good bond with the polyethylene substrate, the steel pipe surface and the solid epoxy coating. During heating, the base layer of the shrink sleeves shrinks, the adhesive layer melts, and the tight shrinkage coats the mouth, forming a firm and continuous anti-corrosion body with the original pipe anti-corrosion layer. Corrosion resistance, wear resistance, impact resistance, UV resistance and photo-aging properties.
Heat shrinkable sleeve application:
Used in oil and gas industry long-distance transportation of oil, natural gas pipe welded joints corrosion, at the beginning of this century, a large number of long-distance oil, natural gas pipe welded joints corrosion, urban gas pipe and water supply and drainage pipe network joint corrosion and so on.
