RSPBJ(S) Fibre Reinforced Wrap-Around Heat Shrinka

RSPBJ(S) Fibre Re-inforced Wrap-around Heat Shrinkable Sleeve Fibre re-inforced heat shrinkable wrap-around sleeve for thermal insulation and oil & gas pipeline 1. Description Construction: Three-layer system or Two-layer system First layer: Liquid epoxy, solvent-free two-component (Two-layer system has no this layer) Second layer: High shear strength copolymer adhesive (First Layer of Two-layer system) Third layer: Radiation cross-linked, high density polyethylene with fibre re-inforced composite structure (Second Layer of Two-layer system) The RSPBJ system is a wrap-around fibre re-inforced heat shrinkable sleeve which replicates the structure and performance of mill-applied three-layer PE coatings. RSPBJ also has excellent compatibility and has been extensively used on many other mill-applied coatings. 2. Features ---High mechanical strength and powerful penetrating resistance ---Limitation of split propagation in case of external damage to the sleeve ---Excellent adhesion performance ---Convenient to use ---Satisfied with special standard or requirements 3. Application ---Oil & gas pipelines ---Thermal insulation pipelines ---Offshore pipelines ---Compatible line coating: PE, FBE, Coal Tar ---Pipe size: 50.8mm 1524mm(2" 6") ---Operating temperature range: up to 80oC 4.
