Insulation that fits like a glove
Rigid polyurethane foams are used, among other things, for the industrial production of pipes. Polyurethane-insulated pipes are installed wherever hot or cold media have to be conveyed from A to B.
The diameter of such pipes can range from a tiny 5 mm to a giant 2,000 mm with insulation thicknesses of up to 250 mm for long-distance heating pipes in the low temperature range. There is, in fact, no better insulating material than Covestro's Baytherm® for pipes used in long-distance heating systems. Its most important function here is to keep the heat exchange with the environment to a minimum. The Baytherm® core, which lies between the inner steel pipe carrying the medium and a concentrically arranged protective tube or jacket, offers maximum heat insulation from a minimum wall thickness. Covestro offers system solutions for both rigid and flexible pipes.
Its key advantages are:
- Broad range of application
- Outstanding insulating capacity
- Good mechanical resistance
- High heat stability when subjected to extremely high temperatures
- Low water absorption
- Energy saving in the transport of hot and cold media
Both continuous and discontinuous processing technologies are available for pipe insulation. The pre-insulated pipes are easy to transport, store and install. Covestro is currently one of the world's leading polyurethane raw material manufacturers for the pipe industry.
