EST Group offers a complete line of Hydrostatic Test and Isolation Plugs for pressure testing of pipe, pipelines and pressure vessels.

Test Open End Pipes, Pipelines, Tubes and Pressure Vessels
Perform Flange-To-Pipe Weld Testing
Isolate and Test Pipe Connections

Test plugs provide safe and effective testing at working pressures up to 15, 000 psi (1034 Bar). Pipe OD and ID sealing versions available.

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.

Also available are hydrostatic test pumps, ideal for use with our entire range of pressure test plugs

Hydra-loc Tube Sleeving

During Heat Exchangers operating life, tubular heat exchangers are often subject to inlet tube end erosion. This erosion occurs over the first few inches of the tube end, often reducing the tube wall sufficiently enough to require the tube to be plugged. Installing a metallic tube sleeve through the eroded area of the tube end mitigates the effects of this erosion allowing the tube to be returned to service, extending the life of the heat exchanger and postponing costly re-tubing or bundle replacement.

Sleeves expand into intimate contact with the host tube
Metallic sleeves are more easily removed than glued in plastic sleeves
Process is faster than conventional roller expansion techniques
Process allows the sleeve to expand and conform to the actual contours

EST's Pop-A-Plugs are installed with Ram Installation Equipment
Installs Pop-A-Plug Tube Plugs Quickly, Safely and Easily
Compact, lightweight and easy to use

GripTight High Pressure Test Plug - Test Open End Pipes, Pipelines, Tubes and Pressure Vessels Quickly and Safely
Unlike other plugs that can loosen and eject under high pressure - even becoming dangerous projectiles the GripTight actually uses test pressure to seal more securely against the pipe's inner diameter.
The greater the pressure - the greater the grip! The result is safer installation, better sealing and all around safer testing.

G-250 Vacuum Tube Testing Guns provide a Fast and Effective Method for Pneumatically Testing Heat Exchanger Tubes and Tube-to-Tubesheet Joints for Leaks
Quickly seal off and evacuate individual heat exchanger tubes to test the tube for leakage
Uses standard plant air supplies from 40 to 125 psi
(2.7 to 8.6 Bar)

G-Series Tube Testing Guns provide a safe, economical way to test for leaks in heat exchanger tubes. Test individual tubes for pinhole leaks using air pressure
Uses readily available shop air pressure to conduct reliable testing of tubes
G-150 Tube Testing Guns are designed for use in Tube ID ranges from 0.28 to 1.23 (7.1 mm to 31.2 mm).
G-150A Tube Testing Guns are designed for use in Tube ID ranges from 1.24 to 2.53 (31.5 mm to 64.3 mm).

CPI / PERMA PLUG - The fast and safe way to seal leaking heat exchanger and condenser tubes in refineries and chemical plants.

Cited in ASME PCC-2-2011 Repair of Pressure Equipment & Piping.

Pop-A-Plugs have the lowest life cycle cost of any tube plugging system.

Quick installation plug installation time less than 15 seconds, maximizing plant uptime. Rated up to 1, 000 psi (68.9 Bar)

Permanent and Reliable - engineered for optimal performance throughout the heat exchangers life cycle.

Patented Internally Serrated Sealing Ring design (U.S. Patent Number 5, 437, 310)

Applications

Condensers, Evaporators & Air Chillers

Shell and Tube Heat Exchangers, Air Cooled Heat Exchangers & Floating Head Heat Exchangers
