Product Description
Closed-type Heat Shrinkable Sleeves
Heat Shrinkable Tubular Sleeves (Forever HSS )
2.1 Product profile
Heat Shrinkable Tubular Sleeves (Forever HSS ) 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.
2.2 Features & Benefits
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.
Forever HSS 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 ℃) ,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
