1. A system for producing a joint between a first pipe element (4) and a second pipe element (5), comprising:
a sleeve (3), wherein the sleeve (3) comprises a plug-in sleeve with a clamping element, wherein the clamping element can be coupled in thrust in a longitudinal direction of the plug-in sleeve, the clamping element being shaped and formed such that, when an axial force is applied by means of a fluid pressure medium, the clamping element exerts a clamping action in the form of a snap-on function on the first pipe element (4) and the second pipe element (5);
a process control means (200) in the form of a compressed air valve controllable by means of a target process parameter (110), by means of which a process parameter (210) in the form of a controlled course of compressed air can be applied to controllable means for producing a permanent and/or detachable pipe joint (6, 6′, 7, 7′) of the plug-in sleeve wherein the clamping action in the form of the snap-on function can be exerted on the first pipe element (4) and the second pipe element (5); and
means for actual value detecting (300) an actual process parameter (10) in form of a compressed air flow at the controllable means for producing the permanent and/or detachable pipe joint (6, 6′, 7, 7′), which delivers the actual process parameter (10) as an electrical actual value process parameter (310) to a control unit (105) of a pipe joint applicator with a control device (100) which determines the target process parameter (110) for controlling the process control means (200) from the electrical actual value process parameters (310).
