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. Its most important function here is to keep the heat exchange with the environment to a minimum. The 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.
Advantages:
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
