The invention relates to a process for manufacturing a fixed, sealed pipe connection between a smooth pipe end and a press fitting which surrounds said end, the press fitting being compressed in a force-fitting and positively locking manner with the inserted pipe end, by means of a compression tool which is placed on it. The invention is characterised in that, once the compression tool is placed in position, the pipe, which has already manually been inserted into the press fitting, and the press fitting, which has been pushed onto the pipe end, are forcibly subjected to a variable force, acting axially, by means of a device arranged on the compression tool, and the closing movement of the jaws for the compression of the press fitting cannot be released until this force assumes a value which is greater than a predetermined adjustable threshold value. …<IMAGE>… |
