WSS Heat Shrinkable Wrappid Sleeves
Heat Shrinkable Wrappid Sleeves is designed for corrosion protection of girth weld joint of buried and exposed steel pipes, especially for 3-layer coated oil and gas pipeline. Construction: 3LPE-Three layer system
First layer: Liquid Epoxy Primer, solvent-free two-component.
Second layer: High shear strength hot-melt copolymer adhesive.
Third layer: Radiation cross-linked, high density polyethylene backing.
Heat Shrinkable Sleeves covered 3LPE Heat Shrink Sleeves，2PE Heat Shrink Tape，3LPP Wrap Around Sleeve HDD Heat Shrink Wrap Sleeves,Shrinkable Tape Closure Patch
During installation, the epoxy primer is applied to the prepared pipe surface and the heat-shrinkable sleeve is immediately wrapped around the joint over the wet or dry 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 & to the copolymer adhesive layer. The radiation cross-linked outer layer forms a tough barrier against mechanical damage and moisture transmission.
Excellent multifunctional adhesive allows for lower installation pre-heat temperature and super bonding to PE, PP and FBE, offer fully resistant to shear forces induced by soil and thermal movements.
Superior cathodic disbondment and hot water immersion resistance offers the optimum barrier long-term protection against corrosion.
Saves time & cost by lower preheat temperature, wet epoxy primer application is ok.
