摘要

The present invention relates to a sealing test method of a pipeline or a network of pipes, as well as a plant for implementing this method. & br / & thus, according to the process: & br / - it defines the pipe or the network of pipes (2, 2a, 4) to be tested by means of closure means (5, 5a, 5b); & br / - a gaseous fluid is injected into the pipe or the network of ducts so as to reach a pressure p data; & br / - this pressure p is maintained constant by addition of gaseous fluid into the pipe or the network of pipes; & br / - the rate of supply of gaseous fluid that is necessary to maintain the pressure p & br / the present invention will find its application in all fields in which it is advisable to test the sealing of a pipeline or a network of pipes, whatever the function of this latter.
