Heat Shrinkable Tubular Sleeves 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 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.
