Method of carrying out pressure test on pressure tank, as well as the pressure tank, pipe unit thereto and method of fastening the pipe unit

摘要

In order to enable conduction of pressure test in a simple manner using capture of sound emissions, first of all by means of efficient employment of a sound emission sensor (12), there is installed on outer side of a pressure tank (2) jacket (6) an in at least one channel (9) at least one sound emission sensor (12) to intercept signals. After pressure test is carried out, the sound emission sensor (12) is removed from the channel (9) and can be used in the same manner for pressure test of the same type on another pressure tank (2).
