Piping refers to a system of pipes used for the transportation of fluids and gases from one point to another. Pipes of various sizes, shapes, and materials are used for different applications, including plumbing, heating, ventilation, air conditioning, and industrial processes. The design, installation, and maintenance of piping systems require specialized knowledge and skills to ensure safe and efficient operation. Piping systems may include valves, fittings, pumps, and other components to control the flow and pressure of the fluids or gases. Proper piping design and maintenance are crucial to avoid leaks, corrosion, and other problems that can affect the performance and safety of the system.
