Abstract: A hydraulic threaded bolt clamping device for tightening and releasing threaded bolts has a pressure medium supply connected to a pressure medium connector. A cylinder rests against a machine part that is to be clamped and a periodically pressure-loaded piston is guided seal-tightly in the cylinder and rests against a threaded bushing screwed onto the threaded bolt. A control device actuates the pressure medium supply for supplying pressure medium to the bolt clamping device. After a nominal value corresponding to a nominal prestressing force has been reached the pressure medium supply is switched off. The nominal screw prestressing force or a corresponding nominal pressure of the pressure medium supply is preset by an input device. A measuring device measures relative displacement of the threaded end of the bolt relative to the cylinder. An evaluation device determines residual actual screw prestress after pressure relief of the bolt clamping device.

Abstract: A make-up assembly and process provides a true power-tight connection between a first and second tubular segment. Each of the segments has an externally threaded male member at one end and an internally threaded female member at the other end. The male member of the first segment is inserted into the female member of the second segment. A primary torque component is applied to the first segment to engage the external threads of the first segment with the internal threads of the second segment and to advance the male member of the first segment into the female member of the second segment. The value of the primary torque component is monitored. An impulse energy component is then superimposed on the primary torque component when a predetermined onset threshold has been reached. Application of one or both of the primary and impulse energy components is discontinued when a predetermined maximum threshold has been reached.
