Localised Weld Test Tools
Hydrostatic Testing
In-Line Weld Test Tools provide hot work barriers and localised hydrostatic testing to verify the integrity of welds or fittings, reducing system downtime, minimising environmental impact and increasing worksite safety.
In-Line Weld Test Tools are commonly used during the maintenance and modification of piping or process equipment, enabling localised pressure testing. Inserted into the piping or equipment component to be tested, In-Line Weld Test Tools provide a fast and efficient method of verifying the integrity of butt welds, joints or other welded pipe components.
Additionally, Inline Weld Test Tools can be used to provide a verified atmospheric barrier adjacent to the hot work source. Once positioned at location and activated these tools provide a verified vapour barrier allowing hot work activities to safely take place.
To conduct a test of the new weld the Inline Weld Test Tool is repositioned over the weld area and hydraulically set, activating the dual elastomer seals and creating a test boundary. The weld test is typically undertaken using water as the test medium, however this can be conducted using inert gas where necessary. The test is typically a strength test of the joint at 1.5 times the design pressure, although can also be used as a leak testing means, typically undertaken at 1.1 times the design pressure.
In-Line Weld Test Tools can be configured with increased seal span to provide a test envelope for valves and branch fittings. Extended tools are available on request configured to suit application.
