Heat Exchanger Maintenance and Integrity Services

The Heat exchanger is designed to exchange heat from one medium to another. If the heat exchanger is dirty or not maintained, it fails at this job, which increases costs to operate, stresses other parts of the systems, and reduces efficiency.

Heat exchangers should be serviced every 6 months - 4 years, depending on their environment. For instance, where dust is a factor, a heat exchanger needs opening and cleaning every 6 months.

Cleaning of Heat Exchanger Tubes and Shells

We remove dirt, scale, oil, and other deposits from the inside of the tubes and outer shell to restore efficient heat transfer and prevent blockages. We provide internal and external cleaning services

It's generally estimated that cooling accounts for around 15% to 25% of total energy consumption in commercial buildings. This figure can be higher in regions with hotter climates or in buildings with inefficient cooling systems.

According to industry studies, dirty tubes can increase energy consumption by 10-30% depending on the severity of fouling. Given that HVAC systems are among the most energy-hungry systems in industrial settings, this can translate to thousands of euros / dollars in added operational costs annually.

Tube Testing, Plugging and Advanced NDT

We archeived this using the G-160 Tube Testing Gun is a high-performance, pneumatic-hydraulic tool used to quickly and safely test individual tubes in shell-and-tube heat exchangers, condensers, and boilers. It allows for efficient detection of tube leaks by sealing both ends of a tube and pressurizing it with air or nitrogen while submerged in water (hydrostatic test), or using soap solution for above-ground tests.

Key Benefits:
• Fast testing: Up to 10 tubes per minute
• No need for pressurizing the entire exchanger
• Safe and controlled testing pressure (up to 125 psi)
• Compact and portable - ideal for on-site services
• Minimizes downtime and enhances inspection accuracy

Flange Facing Services

A flange facer is a tool that creates a flat and parallel surface on flanges to ensure a tight seal, and is important because it helps maintain the integrity of flange joints Flange facing is an essential machining operation that creates new, perfectly flat, and parallel coupling surfaces on the flanges of pipes, valves, and other equipment, ensuring a tight and secure seal when reassembled.

This process is accomplished using a special tool called a flange facing tool, flange facing machine, or flange facer. It is also used by many other industries during plant and heat exchanger maintenance and shutdown.

Our Engineers have attended training in the United Kingdom from BSA tube runner on how to use the equipment for flange facing.
