EST Group, Inc. is dedicated to providing a complete range of lifecycle products and services for tubular heat exchangers, condensers, pipes, piping systems and pressure vessels. EST Group serves the power generation; petrochemical and refining; fine chemical and pharmaceutical; shipbuilding; oil and gas production; and engineering and construction industries worldwide.

The EST group includes:

• EST Group: A global manufacturer and designer of pipe and tube pressure testing and plugging equipment. Since 1968 the company has specialized in development, manufacturing and marketing of tools and 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.
  • Pop-A-Plug® Tube Plugs and Pop-A-Plug Tube Plugging System® - for quickly preparing and plugging leaking heat exchanger tubes. Suitable for service in operating pressures to 7,000 psi (480 Bar) without welding or explosives.
  • Pop-A-Plug® Tube Stabilizers - for stabilizing fractured or severed heat exchanger tubes.
  • G-Series Tube Testing Guns - for locating and identifying leaking heat exchanger tubes and tube-to-tubesheet joints.
  • GripTight® and SQ2 Test Plugs - for high pressure hydrostatic testing of pipe, pipelines and pressure vessels. Safe and effective at working pressures to 14,000 psi (960 Bar). Pipe OD and ID sealing versions available.
  • High Lift Flange/Weld Testing Plugs - for quickly isolating and hydrostatically testing weld joints of any welded flange to pipe connection.
  • Double Block & Bleed Plugs – positively isolate pipe end hot work from potentially explosive upstream vapors; then weld and test the flange to pipe connection all with one tool.
  • D-Series Tapping Tools - compact, lightweight tools for tapping into existing pipelines under pressure; ideal for sampling and/or draining the contents of a pipe or pressure vessel.
• EST Services: Provides a complete range of turnkey field services targeted at the inspection and repair of tubular heat exchangers and condensers - including heat exchanger tube testing, inspection (visual, eddy current or IRIS), mechanical tube cleaning, tube sleeving or lining, tube plugging, tube pulling and partial retubing operations. Sleeves are installed using Hydra-Loc™ hydraulic expansion equipment. EST FS offers piping system and pressure vessel hydrostatic testing and inspection. Additionally EST FS provides on-site training courses for all EST products.
