A Double Pipe Heat Exchanger consists of two concentric pipes, where one fluid flows through the inner pipe and the other through the annular space between the pipes. Its simple, compact design makes it ideal for small-scale applications requiring efficient heat transfer, precise temperature control, and easy maintenance in industries like chemical, oil & gas, food, and pharmaceuticals. https://www.unitedheatexchangers.com/heat-exchanger/Double-Pipe-Heat-Exchanger/
