Leak Test & Plugging Solutions
Lifecycle Products & Services
Engineered products and comprehensive repair services for heat management cooling systems.
EST Group is a global manufacturer and designer of pipe and tube pressure testing and plugging equipments & systems that greatly simplify the maintenance of shell and tube heat exchangers and that speed-up in-service inspection of pipe, pipelines, piping systems and pressure vessels. We provides a comprehensive range of onsite services for heat exchanger troubleshooting and repair as well as turnkey pressure testing services.
1) Pop-A-Plug® Tube Plugging System
EST Group offers a complete line of tube plugs and plugging systems designed for quickly preparing and plugging leaking heat exchanger, condenser and boiler tubes. Plugs are suitable for service in operating pressures up to 7,000 psi (480 Bar) and are designed to be installed without welding or explosives. A variety of systems and tools are available for installation and removal.

Isolation plugs are designed for quickly isolating and hydrostatically testing weld joints of any welded flange-to-pipe connection as well as isolating pipe ends during cutting, grinding and welding operations.
GripTight® Isolation Plug
Isolate and monitor potentially explosive vapors during "hot work", then effectively hydro test the new weld connection with one easy to use tool.
Double Block & Bleed Isolation Plugs
Isolate pipe end hot work from potentially explosive upstream vapors; then weld and test the flange-to-pipe connection all with one tool.
High Lift Flange/Weld Test Plugs
For quickly isolating and hydrostatically testing the weld joint of any welded flange-to-pipe connection.
Also available are hydrostatic test pumps that are ideal for use with our entire range of pressure test plugs.
