Pipe Plug, Very High PSI, Bypass, 147-1 Series

Double Block and Bleed Isolation Test Plug

Positively isolate and monitor potentially explosive vapors during hot work, then effectively hydrotest the new weld connection with this Double Block and Bleed Isolation Plug. The dual-port design of this mechanical plug for hydrotesting creates a positive pressure barrier between the seals - safely isolating hot work from any residual upstream gases. In addition, the volume of water required for a test is so small that testing can be accomplished using a hand pump.

Lightweight aluminum/steel construction makes our hydro test isolation pipe plug for pressure testing 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!

Features & Benefits

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

Double Block & Bleed Applications

Block & Bleed plugs are found in numerous applications, including:

  • Oil, Gas and Chemical Process Plants
  • Offshore Oil & Gas Platforms
  • Shipyards
  • Plant revamps and additions
  • Piping Systems, Spools, Pressure Vessels with Flanged Connections
  • Flange Replacement Programs
  • Tie-In Work

Basic Operation

  • After determining pipe and schedule size, install DBB upstream of “hot work” area
  • Expand seals by tightening compression nuts
  • Inject inert gas or water between seals (isolation zone) and pressurize
  • Monitor isolation zone pressure during “hot work”
  • After weld cools, release pressure and seal, reposition the plug’s isolation zone over the weld area
  • Pressurize isolation zone
