FIELD: physics, trials.
SUBSTANCE: invention concerns field of exploring technics. Device contains tube plugs with sealing devices for hermetic sealing of trailer holes, system for making of pressure of exploring medium (fluid or gas), and a casing which the tested device is put on. The casing is located in tested device with the underload backlash also is fastened to one of the tube plugs. The opposite extremity of casing is executed as the power cylinder with the piston and a rod. On the extremity of rod acting from the cylinder, fastens demountable tube plug. Thus the cylinder is supplied by holes for receipt of exploring medium in a vacuity over the piston from a rod and making of locking efforts on the tube plugs with formation of the closed vacuity between casing and tested device by means of the consolidations located in the tube plugs. For maintenance of tightness the piston area which pressure of exploring medium influences, exceeds the area of the tube plug, being under the pressure of exploring medium.
EFFECT: cutting of duration and material inputs, increase of safety of trials of devices of pipelines by interior pressure.
