Girth Welding Area Corrosion Protective Heat Shrinkable Tubular Sleeve
Heat Shrinkable Tubular Sleeves (HSTS) consist of a cross-linked polyolefin backing, coated with an adhesive which effectively bonds to steel substrates and common pipeline coatings including polyethylene and fusion bonded epoxy. Tubular type sleeves are installed before joining the pipe ends by sliding the coat from a free end of the pipe onto the area to be coated. It is designed for corrosion protection of flanges, casings, bell and spigot joints and other high profile couplings. Heat Shrinkable Tubular Sleeves are superior performance heat shrinkable products designed for corrosion protection of flanges, casings, bell and spigot joints and other high profile couplings. HSTS provide great corrosion protection, Superior resistance to Cathodic Disbondment and excellent durability against abrasion and chemical attack. The result is effective, good performance of sealing, wide application, easy to operate and preheating temperature low (50 centigrade), long term protection against corrosion. Tubular design allows for convenient and fast installation because less time is spent handling the sleeve and closure Cross-linked backing provides superior abrasion, mechanical and chemical attack resistance. High performance adhesive provides excellent resistance to Cathodic Disbondment to ensure long-term corrosion protection Pipeline size: From Ø 30mm to Ø 1000mm Sleeves width: 100mm, 150mm, 200mm, 300mm, 450mm, 500mm, 600mm, 900mm Model: HSTS /510/ Ø 711 HSTS--Heat shrinkable wraparound sleeves 505----- -Roll Width (as supplied) Ø 711----Joint or pipeline Diameter Note: The Size can be ordered according to customers' demand
