Product Description

3LPE Pipeline Corrosion Protective Field Girth Welding Coating Wraparound Heat Shrinkable Sleeve

INSTRUCTION
PE-backed heat-shrinkable sleeve (HSS) for the pipeline is composed of two layers: radiation cross-linked polyethylene backing and special heat melt adhesive. The heat-shrinkable sleeve is applied together with a solvent-free two-component epoxy primer to form a three-layer polyethylene anti-corrosion coating (3LPE), which replicates the structure and performance of 3LPE coating in factory conditions, providing effective and long-term anti-corrosion for the welding joint of the steel pipe.

During installation, the epoxy is applied to the prepared pipe surface and the heat-shrinkable sleeve is immediately wrapped around the joint over the wet epoxy. Heat is then applied to the sleeve which shrinks to form a tight fit around the joint. While curing, the epoxy forms strong mechanical and chemical bonds to the pipe surface and to the copolymer adhesive layer. The radiation cross-linked outer layer forms a tough barrier against mechanical damage and moisture transmission.
