Exchangers
A heat exchanger is a mechanical device used to transfer thermal energy between two or more fluids without direct contact between them. In refinery operations, heat exchangers are critical for optimizing energy efficiency, controlling process temperatures, and supporting various unit operations such as distillation, cracking, reforming, and product cooling.
Description
Heat exchangers in refineries come in various configurations—most commonly shell-and-tube, plate-type, and air-cooled designs—each selected based on process requirements, fluid properties, and operating conditions. Shell-and-tube exchangers are widely used due to their robustness and ability to handle high pressures and temperatures. These units consist of a bundle of tubes enclosed within a shell, where one fluid flows through the tubes and another flows over them within the shell, facilitating efficient heat transfer.

Maintenance activities may include tube plugging, gasket replacement, flange re-torquing, and weld repairs on tube sheets and shells. In cases of severe damage or performance degradation, complete retubing and reconditioning of the exchanger may be required.
Mechanical services for heat exchangers include cleaning, repair, retubing. Cleaning is performed using mechanical methods like brushing and hydro jetting, or chemical methods such as descaling and degreasing, to remove fouling and restore thermal efficiency.
At SnC Infratech, we provide comprehensive heat exchanger services tailored to the demanding conditions of refinery operations. Our expertise spans across shell-and-tube, plate-type, and air-cooled heat exchangers, ensuring optimal thermal performance and mechanical integrity. Our cleaning services include high-pressure hydro jetting, mechanical brushing, and chemical descaling to remove fouling and restore efficiency. Maintenance activities cover tube plugging, gasket replacement, flange re-torquing, and weld repairs on tube sheets and shells. For severely degraded units, we offer complete retubing and reconditioning, along with upgrades to corrosion-resistant materials and improved flow designs. Our team also handles the fabrication and installation of new exchangers, ensuring precise alignment and integration with process systems. All work is executed under strict safety protocols and documented in compliance with ASME, TEMA, and API standards. With a focus on reliability, turnaround speed, and technical excellence, SnC Infratech ensures that your heat exchangers operate at peak performance, contributing to energy efficiency and process stability across the refinery
