A Double Pipe Heat Exchanger consists of two concentric pipes, where one fluid flows through the inner pipe and another through the outer annular space. This simple and compact design enables efficient heat transfer between hot and cold fluids. Commonly used in chemical, oil, and food industries, it offers reliability, easy cleaning, and flexibility for small to medium heat duties. https://www.heatexchanger.co.in/Heat-Exchanger/Double-Pipe-Heat-Exchanger/
