RSPB(S) Wrap-aroundHeat Shrinkable Sleeve Girth weld protection system for three-layer coated pipes 1. Description 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 RSPB(S) series is a wrap-around heat shrinkable sleeve which replicates the structure and performance of mill-applied three-layer PE coatings. RSPB(S) also has excellent compatibility and has been extensively used on many other mill-applied coatings. 2. Features ---High mechanical strength and powerful aging resistance ---Good environment stress cracking resistance ---Excellent adhesion performance ---Convenient to use ---Satisfied with special standard or requirements 3. Application ---Oil & gas pipelines ---Offshore pipelines ---Compatible line coating: PE, FBE, Coal Tar ---Pipe size: 50.8mm 1524mm(2" 6") ---Operating temperature range: up to 80oC 4.
