Cooling Water Insulating Pipes

Cooling water insulating pipes ("pipe-in-pipe" system) were developed to transport cooling water over long distances without significant temperature changes. 

This insulated concentric pipe system, which is filled with PUR foam approved by German regional mining inspectorate LOBA, is used in anthracite (hard coal) mining as well as in tunnel construction.
