HBPE Heat Shrinkable Sleeves


Today, with years of experience and expertise, Raychem RPG has become a force to reckon with and stands tall with a proven track record of providing reliable solutions for the varied needs of its customers.

Whether it is design, supply, installation or maintenance, Raychem RPG is always ready to streamline and simplify customer needs.

Setting benchmarks of innovations and technological advancements, one such engineering excellence is Heat shrinkable wrap-around sleeve, which is designed for corrosion protection of girth weld joint buried steel pipeline, especially for 3LPE/DFBE/FBE/CTE factory applied coating.

Construction Three Layer System
First Layer Two-component, solvent-free Liquid epoxy
Second Layer High shear strength, Hot-melt copolymer adhesive
Third Layer Radiation cross-linked, high density polyethylene with Shrink Indicator pattern.
 

After surface preparation and pre-heating first layer of Liquid epoxy is applied on the pipe surface. Then a heat shrinkable sleeve is wrapped around the pipe joint over wet epoxy. Heat is then applied on the sleeve which start shrink to give excellent tight fit around the pipe joint. Epoxy forms strong mechanical and chemical bond to pipe and Second Layer of the hot-melt copolymer adhesive. Third layer radiation cross linked high density polyethylene provides Mechanical protection for moisture, heat and any damages.

Excellent multi-functional adhesive that allows lower installation in pre-heat temperature and bonding to 3LPE/DFBE/FBE/CTE
Full resistance to shear forces induced by soil and thermal movements.
Superior cathodic disbondment, hot water immersion resistance and Thermal ageing resistance that offers the optimum barrier long term protection against corrosion.
Reduction in time and cost by lower pre-heat temperature, wet epoxy primer application.
Pattern backing system that provides a 'Shrink Indicator' for application of heat and ensures proper shrinkage visibility also allows reliability for the Inspection.
