Question 11

How does Uniquo inspect heat exchangers?

Uniquo inspects heat exchangers through a detailed evaluation process to ensure safe operation, efficiency, and structural integrity. Heat exchangers are critical pressure equipment used in many industries, and regular inspection helps prevent leaks, fouling, and performance loss.
In India, heat exchanger inspection is commonly required in industries such as chemicals, oil & gas, pharmaceuticals, power plants, and manufacturing, in line with safety requirements under the Factories Act, 1948 and applicable state factory rules.

Uniquo’s inspection of heat exchangers typically includes:

  • External visual inspection for corrosion, leakage, and insulation condition
  • Internal inspection of tubes, shell, and baffles (where accessible)
  • Tube integrity checks for fouling, scaling, and blockage
  • Weld joint inspection for cracks or defects
  • Thickness measurement and corrosion assessment
  • Pressure boundary and leak checks
  • Review of operating conditions and maintenance history

Depending on the condition and accessibility, Non-Destructive Testing (NDT) methods may also be used to assess internal integrity without causing damage.
After inspection, Uniquo provides a detailed report with findings, risk assessment, and recommendations for cleaning, repair, or continued safe operation. This helps organizations improve efficiency, prevent failures, and ensure compliance with safety standards.
