Heat Shrink Sleeve HBPE80
Heat Shrink-Sleeve HBPE80

Heat Shrink Sleeve HBPE80, Heat shrinkable wrap-around sleeve is designed for corrosion protection of girth weld joint buried steel pipeline, especially for 3LPE/DFBE/FBE/CTE/HDPE factory coating pipeline.

Application Guide

Recommended Use

As a primerEpoxy Primer in a 3-layer polyethylene coating system for superior corrosion protection of the field welded joints of steel pipes. The RP 09 series epoxy
primer needs to be applied onto the steel surface and onto the line coating if needed, when this line coating is PE, FBE, DFBE, or CTE.

Construction:  Three-Layer system
First layer: Liquid epoxy primer RP09, solvent-free two-component
Second layer: High shear strength hot-melt co-polymer adhesive
Third layer: Radiation cross-linked, high-density polyethylene backing, backing with SIP (Shrink Indicator Pattern)

Feature & Benefits

  1. The excellent multi-functional adhesive allows for lower installation pre-heat temperature and super bonding to PE/DFBE/FBE/CTE/HDPE offer fully resistant to shear forces induced by soil and thermal movements
  2. Superior cathodic dis-bondment and hot water immersion resistance offer the optimum barrier long term protection against corrosion
  3. Saves time and cost by lower pre-heat temperature, wet epoxy primer application
  4. Embossed backing provides a Shrink Indicator Pattern for the application of heat, ensuring correct application heating
  5. Fully resistant to shear force
  6. Completely reform the 3LPE-coated pipes
