The seals are expanded radially against the pipe bore mechanically (upto 4″) or hydraulically (6″ and above) to seal off the area to be tested. The annulus created is then filled and vented with the test medium and pressurised upto the required test pressure which can be upto ANSI 1500.
The tools can be set in both horizontal and vertical piping or inclined if required. Testing is achieved in a fraction of the time (and cost) of a full system test, whilst also reducing the provision and disposal costs associated with large volumes of test medium. Most tools can easily be installed and used by trained personal
