<p>The invention relates to a process for producing a press-fitted pipe connection comprising a press fitting with a stop and a smooth-ended pipe section pressable therewith, in which, after the pipe section is cut, its cut end is trimmed inside and outside and, if necessary, the protective cover of the pipe is removed, the processed pipe end is inserted into the press fitting to the stop and the press fitting is then pressed, by means of a pressing tool with individual pressing jaws that encompass the press fitting, after application of the pressing tool in a force-locking and positive-locking fashion, with the inserted pipe section to form a non-detachable tight pipe connection, whereby toward the end of the pressing the individual pressing jaws complete each other to form a closed pressing chamber. During pressing, in the contact area of at least one pressing jaw with the outer surface of the press fitting, a characteristic stamping is formed, the appearance of which depends on the quality of the pressing.</p> |
