POP-A-PLUG® P2 HIGH PRESSURE TUBE PLUGS
Repair Heat Exchanger Tube Leaks without Welding
When it comes to heat exchanger maintenance for shell and tube condensers and boilers, you need a tube plugging solution you can rely on.
Pop-A-Plug P2 High Pressure Tube Plugs provide a permanent mechanical tube plugging solution for leaking heat exchanger tubes without welding, eliminating potential circumferential cracking and other heat related issues associated with welding.
EST Group’s high-pressure tube plugs maximize uptime by maintaining a helium leak-tight seal that will not eject like friction fit tapered plugs. Pop-A-Plug Tube Plugs ensure stability through a ring/pin design with metallurgy matched to tube material to minimize thermal expansion/contraction issues, and undesirable galvanic corrosion. No welding required.
Pop-A-Plug P2 High Pressure Tube Plugs provide a long-term solution that allows you to plug heat exchanger tube leaks confidently!

HIGH LIFT FLANGE WELD TEST PLUG
Purge, Weld, and Test Flange Connections with One Plug
Reduce the expense, downtime delays, and waste disposal problems associated with conventional flange-to-pipe weld testing with EST Group’s High Lift Flange/Weld Test Plug. High Lift Flange Weld Test Plugs allow you to monitor upstream conditions, isolate and purge the weld area, perform the weld, and hydro test weld joint to ANSI B16.5 requirements using only one tool. No blind flanging upstream, no vacuum truck for evacuating the line, and no X-raying. Each flange test requires a minimum amount of water, eliminating the need to fill the entire line. Use less water and minimize your environmental impact!
Size Range:
3/4" – 24” NPS (DN20 to DN600)
Flange classes 150# to 600#
Higher flange classes available upon request
Standard Seal Material:
Urethane – alternative materials available upon request
Features
- Improved seal-to-pipe Clearance: plug can be easily installed and removed even where there is severe weld protrusion
- Flange-to-pipe welds are tested without pressurizing the entire system
- Ported center shaft allows for upstream monitoring
A flange hydro test plug allows you to monitor upstream conditions, isolate and purge the weld area, and perform the weld with only one tool.
