STATS Type Approved Remote Tecno Plug provides double block and monitor pipeline isolation. The remotely operated plug is pigged through the pipeline to the required isolation location from a pig launcher or receiver. Pipeline isolation plugs require no welding or cutting into live lines, leaving no residual fittings or hardware on the pipeline. Once at the desired location the Tecno Plug is controlled remotely using an extremely low frequency (ELF) inductive system for reliable tracking and accurate positioning of the plug.
The Tecno Plug is hydraulically activated engaging taper locks which grip the pipe wall and radially expand dual elastomer leak-tight seals. The dual seal design provides a zero-energy zone to enable breaking of containment activities to be conducted safely and efficiently.
Applications
- Sectional pipeline replacement / repair
- Isolation valve replacement / valve repair
- Pipeline tie-in / re-routing
- Pipeline abandonment, bypass or decommissioning
- Mid-line pipeline repair / spool replacement
- Dead leg removal
Specification
- 10” – 56”
- Pressure up to 200 bar
Key Features
- Available as 3D bend compliant as standard with 1.5D on request
- Dual compression elastomer seals are highly effective even in pipelines with corrosion and ovality issues
- High integrity isolation, taper lock grips provides twice the required lock contact area i.e. 100% contingency
- Dual seals provide double block and monitored pipeline isolation
- Fail-safe design feature; taper lock grips and seals energised by differential pressure; referred to as self-energisation
- Self-energisation feature maintains safe isolation while differential pressure exists across the plug
- Both seals fully energised by pressure – rubber pressure 1.1 – 1.4 times greater than pipeline pressure
- Reverse pressure can be applied across the Tecno Plug to facilitate system leak testing
- The Remote Control Module provides a robust system for safety critical activities. Certain Remote Control Modules can be made available for use in a Zone 2, Potentially Explosive environment. The communication antenna and field cable are available for use in a Zone 1, Potentially explosive environment.
- Through-wall communication is achieved using an extremely low frequency (ELF) inductive system for reliable tracking and accurate positioning
- Remote Tecno Plug does not use lithium batteries negating the need for Emergency Response Procedures for the transportation / use of extremely hazardous materials
