Heat Exchanger Tube Plugging Tools and Leak Testing Equipment

 

What Are Tube Plugging Tools and Tube Leak Testing Equipment?

Tube plugging tools, including mechanical tube plugs and driven plugs, provide short-term solutions for leaking tubes, allowing systems to keep running during repairwork. Mechanical plugs create helium-tight seals, while driven plugs adapt to different tube sizes for quick use.
Tube testing tools help detect leaks and verify tube integrity. Vacuum leak testers pinpoint leaks with precision, hydrostatic testing pumps pressurize tubes for water-based inspections, and tube pressure testing tools use air pressure for fast leak detection.

Tube Plugging Products

EGI supplies multiple tube plugging systems designed for temporary and long-term tube isolation applications across heat exchangers, condensers, and boiler systems.

• Mechanical tube plugs: Provide helium-tight sealing performance for high-pressure industrial applications.
• Driven tube plugs: Deliver fast deployment and adaptability across varying tube sizes during outage and emergency maintenance work.
• Pop-A-Plug® tube plugs: Engineered for demanding condenser, chiller, boiler, and heat exchanger environments while helping protect tube sheets and maintain operational integrity.

Tube Testing Tools

EGI’s industrial testing tools help maintenance teams identify leaks, validate repairs, and maintain system reliability before returning equipment to operation.

• Vacuum testing guns / vacuum leak testers: Fast, accurate leak detection for boilers, condensers, and heat exchangers with lightweight, field-ready operation.The KVLD-3000 quickly detects leaks in boilers, condensers, and heat exchangers. One lightweight tool covers ¼”–3” tubes, features a built-in vacuum gauge, and operates quietly at 90 PSI.

• Hydrostatic test pumps: Industrial-grade pumps designed for high-pressure tube and piping system testing applications.Pumps for petrochemical and pipe testing, built with stainless-steel and bronze components. Features a wheeled design for easy maneuvering, and each unit is factory-tested.
• Tube pressure test tools: Reliable full-length tube integrity testing designed to improve inspection speed and reduce maintenance labor requirements. Curtiss-Wright EST Tube Testers check the full length of a tube between tube sheets with one button. Air pressure expands seals sized to the tube I.D., and gauges hold pressure if no leaks are detected. This fast, reliable method reduces labor and speeds leak identification.

Industrial Applications for Tube Plugging and Testing Equipment

EGI’s plugging and testing solutions support industrial maintenance programs requiring reliable leak detection, tube isolation, and system integrity verification.

Common Applications Include:

• Petrochemical plant heat exchanger maintenance
• Power generation condenser and boiler tube inspections
• Refinery turnaround and shutdown maintenance
• HVAC and industrial chiller maintenance
• Emergency tube failure response applications
• Critical path maintenance and outage repair work

 

When to Plug vs. When to Test?

Understanding when to plug or test tubes is important for efficient maintenance in industrial applications. Different methods serve different purposes: vacuum leak testers for quick pinpointing, hydrostatic pumps for pressure-based verification, and tube pressure testing tools for full-length assessments.

• Plugging first: Used when a tube is confirmed to be leaking, and immediate isolation is needed
• Testing first: Applied during inspections to locate leaks before committing to repairs

Tube Plugging and Testing FAQs

How do I test tubes for leaks?

Leaking tubes can be tested with vacuum leak testers, tube pressure tools, or hydrostatic pumps. Use vacuum testers for fast detection in boilers, condensers, or heat exchangers. Use tube pressure tools to check the full length of each tube with air pressure. Hydrostatic pumps can be used to apply water pressure along the tube to verify integrity under conditions similar to normal operation.

What are the best tube plugging tools for heat exchangers?

Mechanical tube plugs like Pop-A-Plug® CPI/Perma and driven plugs provide reliable solutions for isolating leaking tubes in condensers, boilers, and heat exchangers.

Vacuum vs. pressure tube testing – which should I use?

Vacuum testers are best for quick detection, pressure tools for full-length inspection, and hydrostatic pumps for water-based testing. Combining methods ensures accurate leak detection and effective tube maintenance.
