Abstract
A method manufacturing a spacer for a pipe-in-pipe system includes mixing aerogel particles with a polymer to form a mixture in which the particles are dispersed in the polymer. The resulting mixture is moulded and the polymer is solidified to form the spacer or a component of the spacer, in which the dispersed, particles are suspended in a matrix of the solidified polymer.
Claims21
A method of manufacturing a spacer for a pipe-in-pipe system, the method comprising:
- mixing a filler of aerogel particles with a polymer to form a mixture in which the aerogel particles are dispersed in the polymer;
- and
- moulding the mixture and solidifying the polymer to form the spacer or a component of the spacer, in which the dispersed aerogel particles are suspended in a matrix of the solidified polymer, wherein the polymer is a thermoset and is solidified at a temperature of from 30° C. to 250° C.
