In the field of pipeline anti-corrosion engineering, although 3PE heat shrink tape and ordinary heat shrink tape are both used for pipeline interface protection, there are obvious differences in actual performance and application effects.
3PE heat shrink tape adopts a unique three-layer composite structure design, with excellent anti-corrosion performance, mechanical strength and sealing effect, especially suitable for high-demand scenarios such as long-distance oil and gas pipelines and chemical pipelines. In contrast, ordinary heat shrink tapes usually use single-layer polyethylene or simple double-layer structures, mainly relying on hot melt adhesive to achieve sealing, and are obviously inferior in anti-corrosion grade and service life.
From the perspective of practical application, 3PE heat shrink tape can maintain stable performance in the extreme temperature range of -40℃ to 80℃, and its service life can reach more than 30 years, while ordinary products are prone to aging in high temperature environments.
3PE heat shrink tape is a high-end anti-corrosion solution suitable for harsh working conditions; ordinary heat shrink tape focuses more on economy and convenience, suitable for general protection needs.
