RSPBJ(S) Fibre Reinforced Wrap-Around Heat Shrinkable Sleeve

RSPBJ(S) Fibre Reinforced Wrap-Around Heat Shrinkable Sleeve
Product Detailed
RSPBJ(S) heat shrinkable sleeve replicates the structure and performance of mill-applied three-layer PE coatings.

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
