Abstract
A compensator of pliable material for establishing a flexible joint in a pipe, comprising at least one flexible layer of fabric material cooperating with a sealing element of limited thermal stability. A layer of flexible steel foil is disposed between the sealing element and at least one thermally and/or chemically stressed side of the compensator.
Claims7
A compensator of pliable materials arranged in a laminar fashion for establishing a flexible joint between sections ofa pipe, comprising:
- a sealing layer of a fluid-impervious material having a limited thermal stability;
- a flexible layer of fabric material positioned adjacent to and on each side of said sealing layer;
- and
- a non-load-bearing layer of flexible, metallic foil positioned adjacent to said sealing and said flexible layers, said layer of flexible, metallic foil being disposed relative to said sealng and said flexible layers so as to protect said layers against a source of thermal and/or chemical stress.
