Expandable Tube Plugs for Condenser and Heat Exchanger Tubes
Expandable tube plugs represent an advanced technical solution for sealing condenser and heat-exchanger tubes in industrial installations. Designed to provide controlled expansion inside the tube through elastomeric or composite materials, they ensure reliable leak-tight sealing while minimizing mechanical stress on the tube walls and the tubesheet.
An ideal solution for tube maintenance
These plugs are particularly well suited for preventive and corrective maintenance operations, offering a safe, reusable and fast-to-install solution for isolating defective tubes without requiring heavy replacement work or welding.
Performance and Design
Controlled expansion using high-performance elastomeric or composite materials, allowing precise and rapid installation according to tube diameter.
Temporary or permanent service capability, depending on operational or maintenance requirements.
Engineered to withstand pressure fluctuations, temperature variations and vibration, ensuring long-term operational reliability.
Simple, non-damaging installation that preserves tube and tubesheet integrity, reducing intervention time and maintenance costs.
Industrial applications
Expandable tube plugs are suitable for a wide range of industries where heat exchangers and condensers must remain in service with minimal downtime, including:
- Power generation plants (nuclear, thermal, biomass)
- Oil & gas and petrochemical facilities
- Metallurgical and chemical processing industries
- Marine and offshore systems
Thanks to their versatility and robust design, expandable tube plugs provide an effective and flexible solution for managing tube leaks and optimizing maintenance operations.
Supply & installation by specialized teams
In addition to the sale and supply of sealing plugs, IMS PLUGS can deploy dedicated teams of specialized technicians for on-site plugs installation.
Our teams are fully mobile throughout Europe and have strong field experience, with several hundred plugs installed each year in demanding industrial environments.
