Covalence - Heat Shrinkable Technology

Covalence - Heat Shrinkable Technology

COVALENCE® – The original Heat-shrinkable Technology, we invented it in 1957. The product line consists of a series of 2- and 3-layer heat-shrinkable sleeves for applications including pipeline field joint corrosion prevention, mechanical protection, and sealing of district heating and district cooling pipelines.


About Covalence.
The product line consists of a series of heat-shrinkable multi-layer sleeves that have high electrical resistance and low permeability, making them the optimal solution for corrosion prevention for steel pipelines and sealing of pre-insulated piping systems. The products consist of an irradiation cross-linked & stretched polyolefin backing with an adhesive laminated on in order to form the basic product. The adhesive may be either visco-elastic based mastic or co-polymer hot melt adhesives to match up with in-service performance requirements.
Features & Benefits.
  • Irradiation Cross-linked polyethylene and polypropylene backings.
  • Adhesives formulated for maximum corrosion prevention at low, ambient and high pipeline operating temperatures.
  • 100% solids epoxy primers for 3-layer systems utilizing "wet-system" application technology.
  • Products tailored for specific applications from large diameter water pipelines to high temperature oil & gas pipelines.
  • Global sales and technical support teams
