Dual Tool

Application

iNPIPE’s isolation tool, The Dual Tool, is used when a new flange must be welded to existing pipe work which has been carrying hydrocarbon resources. In this instance, a safe working environment must be created before hot work can commence. The role of the Dual Tool is to provide isolation via a combination of inflatable tyres and water.

Once the weld has cooled the tool can then be repositioned and the central cavity used to hydrostatically test the new weld.
