HSS60 Heat Shrinkable Sleeve 3 layer wet film application ISO21809-3 14B-1

　　HSS60 Heat shrinkable wrap-around sleeve is designed for corrosion protection of girth weld joint buried steel pipeline, be suitable for use up to a continuous operating temperature upto 60℃ in wet conditions (as verified by hot water immersion testing) and shall be fully compatible with 3-layer PE factory applied pipeline coating.The sleeve be suitable for ambient conditions where the black body temperature of pipe and coatings can reach 65℃.

　　Construction:  Three-layer system

　　First layer:   Solvent free 100% solids novolac epoxy with two-component

　　Second layer:  High shear strength hot-melt copolymer adhesive

　　Third layer:   extruded radiation cross-linked heat shrinkable high density polyethylene backing with TIP (Temperature Indicator Pattern) is optional.

　　Features & Benefits

　　Excellent multifunctional adhesive allow 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.

　　Pattern backing provides a “heating temperature indicator” for application of heat, ensures correct application heating.
