The present invention relates to a disintegratable plug apparatus for use in connection with petroleum wells, especially during pressure testing of such petroleum wells, wherein the plug apparatus comprises an outer housing surrounding at least one sealing device and a plurality of supporting bodies, at least one of the supporting bodies being in engagement with a locking device for locking to a locking sleeve, the at least one supporting body being brought out of engagement with the locking device after application of a predetermined pressure on the plug apparatus, whereby the at least one supporting body and the at least one sealing device are permitted an axial movement in the outer housing, this movement resulting in the at least one sealing device being brought into contact with loading devices adapted to subject the at least one sealing device to load so as to produce disintegration of the at least one sealing device. |
