What is the maximum pressure allowed when pressurizing a low-pressure system for leak-detection purposes?

The maximum pressure allowed when pressurizing a low-pressure system for leak-detection purposes is 10 psig. This limit is established to ensure safety and to prevent damage to the system while still allowing for effective leak detection. In low-pressure systems, pressurizing above this limit can lead to the risk of rupturing components or causing leaks, thereby undermining the testing process. Following this guideline helps maintain the integrity of the system during maintenance and ensures compliance with industry regulations.
