The Dual Tool is the ideal testing and isolation solution for piping systems carrying hydrocarbon resources. It can be utilised as an isolation tool to provide safe atmosphere for welding to take place by providing a vapor isolation from residual LEL’s. Not only is the Dual Tool an isolation tool but it can also provide the ability to pressure test welds. Using a combination of water and inflatable tyres, the Dual Tool will test pipe integrity after new tie-ins have been welded.
