Pneumatic testing is a method used to check the integrity of pipes, tanks, and other structures by using compressed air or gas. This process helps identify leaks or weaknesses in the material, ensuring safety and reliability. It is commonly used in industries such as oil and gas, construction, and manufacturing. During pneumatic testing, the object is pressurized with air to a specified level. Technicians then monitor for any drop in pressure, which indicates a potential leak. This testing method is often preferred for its speed and efficiency, making it a valuable tool in quality control and maintenance.
