Double Block and Bleed Isolation Plug/Test
Brand: Curtiss-Wright Corporation
The Double Block and Bleed - DBB plug enables you to positively isolate and monitor potentially explosive vapors during “hot work”, then effectively hydrotest the new weld connection with one easy to use tool.
The aluminum/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.
Features- Lightweight, Aluminum and Steel Construction
- Monitor Potentially Explosive Vapors During Hot Work
- The Dual-port System Allows Water to be Circulated Between Seals, Providing Improved Cooling During Pre/Post-Weld Procedures
- Uses Less than a Gallon: 3.8L of Test Media - Cutting Down on Fill Times and Reducing Waste/Treatment Expenses.
- ASME PCC-2 Type IV Testing Device
- Test Pressures To 2250 PsiG: 155 BarG Between The Seals
- Available for NPS Ranging from 3/4” to 24”: DN20 - DN600
- Pressure Tests Performed with Less than a Gallon Of Water
