Product Description
Cross-linked PE Backing Corrosion Protective Black heat shrink sleeves for pipes buried
Product description:
HSS60 sleeve 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: 3-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.
Installation: | ||||||||
During installation, the epoxy primer is applied to the prepared pipe surface and the heat shrink sleeve is immediately set 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 & to the copolymer adhesive layer. The radiation cross-linked outer layer forms a tough barrier against mechanical damage and moisture transmission. | ||||||||
Product features/benefits: | ||||||||
• 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. | ||||||||
