Method of manufacture of a multilayer thermal insulation around and along a solid through part, in particular a filling neck of a tank intended to contain a cryogenic fluid, and corresponding cryogenic tank.

摘要

In this method, which is of the type described in the main patent, for each insulating layer, the insulating strip 5 is first of all applied to the through part 1, so that the internal marginal part 51 of this strip covers a small fraction h of the length of the through part, then the cord 6 is wound onto the said marginal part, thereby immobilising the latter on the through part. <IMAGE>
