ABSTRACT:
A pipe connection for instruments or machines, with a flange on the machine side, which has a means of attachment for connecting a flange on the pipe side. The pipe connection is easy to install and can withstand a great amount of stress, and has the following characteristics as primary elements: (a) a free pipe socket is provided on the machine side; (b) the flange on the pipe side, a clamp element, and a chamber part are loosely pushed onto the butted pipe end, and these can be pressed together by the means of attachment; (c) a seal surrounds the joint between the socket and the pipe end, and both axial ends of this seal project into a seal chamber; (d) the flange on the pipe side and the chamber part between them form a clamp chamber into which the clamp element is inserted; and (e) the clamp edge radially interior to the clamp element rests on the pipe end, is overlapped, with respect to a clamp edge which is radially on the exterior, by a clamp surface of the clamp chamber, and projects out of the clamp chamber in an axial direction in such a way that an axial pressure applied to the clamp element results in an increase in the exterior diameter and a decrease in the interior diameter of the clamp element.
