   Holes in the tube sheet As a building material for the tube socket, e.g. B. a polyethylene or polyvinyl chloride can be used, the elasticity of which can be adjusted to a suitable extent by plasticizers.



    PATENT CLAIMS:
1. Heat exchanger with a bundle of parallel tubes and at least one tube sheet in which at least one end of each tube is held by means of a pipe socket made of elastic material, u. betw. in such a way that one end of the pipe socket engages elastically and sealingly in the holes of the tube sheet and with the other end elastically and sealingly clings to at least one of the pipe surfaces in the region of the pipe ends, characterized in that the pipes (1) are in front of the The tube sheet (2) ends and the flow path between the tubes and the tube sheet is limited by pipe sockets (3) made of plastic.
