The Double Block and Bleed (DBB) plug enables you to positively isolate and monitor potentially explosive vapours during “hot work”, then effectively hydrotest the new weld connection with one easy to use tool.
The aluminium/steel construction makes the tool highly portable, and easy to position.
The volume of water required for a test is so small that testing can be accomplished using a hand pump.
