FRY is a heat-shrinkable, tubular sleeves which prevent corrosion of welded pipe joints in distribution lines for sizes up to DN1000. This mechanically strong and flexible sleeve is compatible with all standard pipeline coatings and outer jackets.
Construction: Three-layer system
First layer: Liquid epoxy, solvent-free two-component
Second layer: High shear strength copolymer adhesive
Third layer: Radiation cross-linked polyethylene
The FRY heat shrinkable tubular sleeve is mainly applied to provide anticorrosive protection for field welding and insulation mending in buried or aerial. Also it is available to provide sealing and anticorrosive protection for flanged joint and insulated flange.
