An expansion compensator for pipelines of the type including a metal casing lined with refractory materials, said compensator comprising:
- a corrugated sheath having its ends sealingly connected to said casing of adjacent portions of the pipeline mounted in a spaced relation to one another;
- shells having a diameter which is substantially smaller than the diameter of said casing, said shells being arranged within said casing;
- rings disposed between said casing and said shells and sealingly connected thereto;
- further rings, which are nearest to the space between the adjacent portions of the pipeline, said further rings being disposed between said casing and said shells and connected to one thereof and extending towards the other to define passages for a coolant supply beneath said corrugated sheath;
- annular distributing chambers for said coolant supply beneath said corrugated sheath arranged at either side of said space and at the inner side of said casing, each of the distributing chambers being formed by the inner surface of said casing, said shell, one of said first-mentioned rings sealingly connected to said casing and said shell and one of said further rings which is the nearest one to said space;
- and pipes for said coolant supply connected to said annular distributing chambers.
