Heat Exchanger Inspection

Possible factors affecting the performance and productivity of heat exchangers  

• Corrosion beneath deposits from cooling water in tubes
• Corrosion caused by the process (electrochemical, galvanic)
• Stress-corrosion cracking (SCC)
• Steam / Condensate Corrosion
• Deposits, contamination or scaling on the inner walls of the pipes caused by the process

How is the measurement of one-dimensional acoustic waves in tubes carried out?

1. Investigation by introducing an acoustic pulse into the tube
2. Return echoes caused by defects can be recorded and analysed.
3. A series of proprietary, patented algorithms identifies and reports the exact location, type and size of the damage to the inner pipe diameter.

How can I minimise downtime when using this system?

1. Minimising downtime

• Around 1,000 tubes are inspected during a 10-hour shift
• The inspection requires minimal resources and consumables

2. Effective decision-making 

• Accurate and reliable results based on 100 per cent inspection
• Effective corrective measures such as tube plugs, replacing the piping or even changing the process operating procedure can be implemented at short notice

3. Preventive maintenance

• Risk mitigation linked to production volume
• This provides an overview of the equipment’s service life

Non-destructive testing of tubes

The human factor increases with the complexity and level of development of NDT (non-destructive testing) technology.
Troubleshooting and identifying faults in tubes requires reliable technicians and technologies.

The technologies used to inspect heat exchanger tubes are changing rapidly and evolving constantly. The variety of test results depends on two factors: the equipment and the operators’ experience.

This system offers significant advantages in pipe inspection by minimising downtime and improving productivity through longer plant operating times.

What are some typical industrial applications?

• Surface area and stability in condensers
• Coolers for corrosive process water
• Propylene condensers
• Ammonia cooler
• Air-cooled fan
• Water boiler
• Process Coolers and Heaters
• Large-water-volume boiler
• Steam condensers
• Other shell-and-tube heat exchangers

Unique key features and special characteristics

• Pipe dimensions up to 4" or approximately 100 mm in diameter, regardless of the material (ferrous, non-ferrous, plastic or carbon)
• Whether U-tubes, bent, spiral-wound or twisted tubes
• Non-destructive inspection – ultra-fast
• Less than 10 seconds per tube
• There is no need to keep a stock of consumables
• Trained staff require only a limited amount of specialist knowledge
• The test is easy to carry out
• Artificial intelligence interprets the data and generates the report.
