SYNOPSIS

The oil and gas industry relies heavily on heat exchangers to manage the temperature of various process streams in Refinery and Petrochemical Plants. Different types of heat exchangers are used for different applications, such as shell-andtube exchangers, plate-and-frame exchangers, and finned-tube exchangers. The industry depends on heat exchangers as a critical component in the Plants’ processes. As such, companies invest in ensuring the proper design, fabrication, construction, maintenance, and inspection of their heat exchangers to ensure optimal performance and safety.

Heat exchangers consist of several parts, including the shell, tubes, baffles, headers, and tube sheets. These parts were designed and fabricated in accordance with various codes and standards, such as the ASME Boiler and Pressure Vessel Code, API standards, and ISO standards. Maintenance of heat exchangers is critical to ensure efficient and reliable operation. Routine maintenance activities include cleaning, inspection, and repair of damaged parts. Inspection of heat exchangers can be performed using various non-destructive testing techniques, such as visual inspection, ultrasonic testing, and radiography.
