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
