Inspection of Shell and Tube Heat Exchangers

Introduction of book:

Shell and tube heat exchangers are among the most widely used types of heat exchangers in industries such as oil and gas, power generation, chemical processing, and HVAC systems. Their robust design and adaptability to a wide range of temperatures and pressures make them a preferred choice for critical heat transfer applications. However, ensuring their safe and efficient operation depends heavily on regular inspection, maintenance, and troubleshooting.

The Inspection of Shell and Tube Heat Exchangers handbook is a comprehensive guide designed to equip engineers, technicians, and professionals with the knowledge and techniques required to inspect, assess, and maintain these essential systems effectively.
