Heat-Shrinkable Sleeve Tape

Designed for corrosion protection and insulation of buried or above-ground steel pipelines, this heat-shrinkable sleeve is primarily used for pipeline joint protection, bend wrapping, and damaged coating repairs. It can also be applied to entire pipes or irregular surfaces for complete corrosion protection. The sleeve consists of radiation-crosslinked polyolefin backing and a specialized hot-melt adhesive that bonds securely to polyethylene substrates, steel surfaces, and epoxy coatings.

The product offers excellent thermal and UV aging resistance, withstanding soil stress, hydrostatic pressure, cathodic disbondment, and chemical corrosion to provide long-term pipeline protection. Chuanshuang’s heat-shrink sleeves exceed national technical standards in tensile strength and elongation retention, ensuring reliable pipeline operation. During installation, heat application causes uniform radial shrinkage while the adhesive melts to form a continuous, tight seal with the existing pipeline coating.
