Heat Shrinkable Sleeve 3LPE, EPDM, and Coated Pipelines

Key Features and Benefits:

High Temperature Performance (120°C): Designed to withstand continuous operating temperatures of up to 120°C , meeting the demanding thermal requirements of deepwater and high-temperature subsea pipelines.

Enhanced Corrosion Protection: Formulated with a high-performance thermoplastic hot melt adhesive engineered to deliver exceptional peel strength and cathodic disbondment resistance at 120°C service, creating a tenacious and durable barrier against corrosion

Reliable Sealing & Pressure Integrity: Provides a comprehensive, moisture-proof seal. The adhesive flows to conform to pipe contours and adjacent coating surfaces, effectively preventing the ingress of water and corrosive elements.

Durable Polyolefin Backing: Features a thick-wall, irradiated cross-linked polyolefin backing for superior mechanical strength. Upon heating, it exerts significant radial shrinkage (hoop stress) on the joint, enhancing adhesion and creating a tight, compressive seal resistant to soil stress and hydrostatic pressure.

Optimized for HDPF Integration: Specifically designed for seamless chemical and mechanical compatibility with High Density Polyurethane Foam (HDPF) joint infill systems. It ensures a reliable interfacial seal during HDPF curing and provides a stable substrate for the infill, preventing gaps or disbondment.

Versatile & Easy to Install: Designed for straightforward field installation. The tape can be applied to complex geometries. Upon heating, the backing shrinks and the adhesive flows to form a reliable protective seal. A pre-installed closure patch ensures complete overlap coverage.
