product description:
The anticorrosive heat-shrinkable sleeve consists of a three-layer structure composed of a radiation cross-linked polyolefin outer layer, a two-component liquid epoxy primer and an inner layer of hot melt adhesive. The main function is to seal, waterproof, anti-corrosion, and protect exposed metal parts. Mainly used in oil or natural gas long-distance pipelines, anti-corrosion at the welded joints of thermal insulation pipelines, pipeline flange connections, insulating flanges and sealing and anti-corrosion of clamp parts.
