Internal Weld Tester

The Internal Weld Tester is used to hydrotest the integrity of a new weld. This can either be a new weld neck flange or an adjoining weld within a pipeline. The traditional method to prove the integrity of the weld would be to flood the whole pipeline and carry out a hydrotest. This is time consuming and potentially very costly. The Internal Weld Tester overcomes this problem as it isolates the testing area, reducing time and resources required.
