Long-distance oil and gas pipelines are commonly applied with three-layer polyethylene (3PE) anti-corrosion coatings, and the matching joint coating material is radiation-crosslinked polyethylene heat-shrinkable tape, which consists of a double-layer material of a substrate and a hot-melt adhesive layer.1 Polyethylene joint coating is a key measure to ensure the long-term safe and reliable service of oil and gas pipelines, and its bonding quality is directly related to the corrosion protection effect of the
