Description
The Dual Tool – Twin Tyred Isolation Plug is the ideal testing and isolation solution for pipelines carrying hydrocarbon resources
Developed at client request to provide a double block and bleed isolation barrier whilst conducting hot work. The Dual Tool has been developed beyond the original concept to provide not only a plugging isolation role but also to provide the ability to pressure test welds. New innovations include flexible dual tools to traverse pipeline bends and ensure full recovery following successful pressure testing.
Benefits of Dual Tool – Twin Tyred Isolation Plug
- Easily installed and operated
- No special tools required
- Accommodates a wide range of pipe schedules
- Design tolerance accommodates ovality and excessive weld bead penetration
- Temporary double block and bleed isolation protection for hot work repairs
- Conducts hot work isolation and then hydrostatic weld testing of the new weld
- Gauges, braided hoses and valves supplied as standard
- Online monitoring of internal tyre pressures (independently monitored), monitoring of internal cavity pressure between tyres) and down-stream pressure
