Leak testing is a process used to identify and locate leaks in various systems, such as pipes, tanks, and pressure vessels. This testing ensures that products and structures are safe and efficient by preventing the loss of fluids or gases. Common methods include pressure testing, vacuum testing, and dye penetration testing, each suited for different materials and applications. The importance of leak testing spans multiple industries, including manufacturing, automotive, and aerospace. By detecting leaks early, companies can avoid costly repairs, enhance safety, and improve overall performance. Regular leak testing is essential for maintaining the integrity of systems and ensuring compliance with industry standards.
