Abstract: Pipe processing apparatus comprising a stamping tool for applying peripheral embossing and/or peripheral stamping to a pipe end section of a pipe, characterised in that the pipe processing apparatus comprises a template which has a pipe sleeve which can be inserted in the pipe end section and having at least one contact surface region, wherein the contact surface region is designed and equipped to limit the insertion depth of the pipe sleeve by means of positive locking between the contact surface region and at least one part region of a pipe end of the pipe end section facing the contact surface region and to position the stamping tool in a work position on the pipe end section as a stamping tool counter-surface.

Abstract: The invention relates to an arrangement for connecting pipe elements, comprising a first pipe element having at least one locking means arranged on the pipe inner wall, a second pipe element having an end section, wherein the second pipe element can be inserted into the first pipe at least in the region of the end section, a separate sealing means arranged at least in a part region of the end section to be completely surrounding its pipe outer wall, equipped to seal a connection between the first pipe element and the second pipe element, characterised in that the sealing means is equipped and designed at the same time as an arresting means to arrest the first and second pipe elements with each other while engaging the sealing means with the locking means.
