Shrink Sleeves for Girth Welds, Directional Drilling and Repair
To provide the optimal solution for each application, Covalence HSP offers a range of products based on an irradiated crosslinked polyethylene carrier, combined with a hotmelt or mastic coating.
The main purpose of the crosslinked carrier, called ‘backing’, is to provide a strong barrier against electrical current, permeation and mechanical forces.
Covalence HSP has over 40 years of experience in the development and manufacture of heat-shrinkable products.
