4. Double-Pipe Heat Exchangers As the simplest design, this type consists of one pipe fitted inside another. One fluid flows through the inner pipe, while the other flows through the outer shell. Though less efficient than other designs, double-pipe heat exchangers are straightforward to install and maintain.

A gas pressure reducing valve typically consists of several key components the valve body, diaphragm, spring, and adjustment screw. The valve body is where the high-pressure gas enters and the reduced pressure gas exits. The diaphragm acts as a responsive mechanism that reacts to changes in pressure. It expands or contracts to maintain consistent output pressure by regulating the valve's opening. The spring applies a force that keeps the diaphragm in position, while the adjustment screw allows for fine-tuning of the desired outlet pressure. Together, these components work seamlessly to ensure that gas is delivered at a safe and usable pressure.
