Safe and Effective Pipeline Pressure Testing
Positively isolate and monitor potentially explosive vapors during hot work, then effectively hydrotest the new weld connection with EST Group’s Double Block and Bleed Isolation Plug. The dual port design creates a positive pressure barrier between the seals - safely isolating hot work from any residual upstream gases.
Lightweight aluminum/steel construction makes our pipe isolation plug easy to maneuver, often-allowing operators to forego the use of lifting devices or cranes, which can be in high demand during turnarounds.
Our 8” schedule 80 Double Block and Bleed Isolation Plug weighs in at just 36lbs (16.3kg) compared to other plugs weighing in excess of 100lbs (45.4kg) of the same size!
