Plug Three Type

The “Plug 3 Type” system allows for under-pressure boring of main pipelines using a divided tee and plug (valve) system. The plug is inserted through a precision-cut bore at the top of the main pipe and seated within the tee, enabling flow isolation without interrupting service.

Live Installation Under Pressure
Enables boring and plug insertion on active pipelines without shutting down flow.
Selective Boring
Only the top section of the main pipe is bored for plug insertion—reduces time and complexity compared to full-pipe boring.
Safety Assurance
Hydrostatic testing after tee installation confirms secure and leak-free operation.
Structural Integrity Maintained
The design preserves the original strength of the host pipe.
Easy Maintenance
The plug can be removed on demand, simplifying future repairs and control operations.
