Insulating element for a pipe for transporting hot gases, and method of implementing such a pipe

摘要

The present invention principally relates to a thermal insulation element (200) of cylindrical shape for a fluid transport pipe comprising an envelope (204) of longitudinal axis (X), a thermal insulation arranged in said envelope (204), the envelope (204) comprising a deformable annular zone, comprising a first (212.6) and a second (212.12) cylindrical surface that overlap and are able to slide against each other in the case of movement imposed by thermal loads applied to said pipe insulation element (200). The present invention also relates to a method of fabricating pipes for transporting fluids at high temperature, particularly hot gases, from elements according to the present invention by fitting a male connector of one element into a female connector of the other element.
