Piping materials are essential components used in various systems to transport fluids, gases, or solids. Common materials include steel, copper, PVC, and PEX. Each material has unique properties, such as strength, flexibility, and resistance to corrosion, making them suitable for different applications in industries like construction, plumbing, and manufacturing. The choice of piping material depends on factors like temperature, pressure, and the type of fluid being transported. For instance, PVC is often used for water supply systems due to its lightweight and corrosion-resistant nature, while steel is preferred for high-pressure applications because of its durability and strength.
