Pipeline sensitivity leakage test

Pipe sensitivity leakage testing is generally used to detect the presence of minor leakage points in pipeline systems, as well as to determine whether such leaks could have an impact on the environment. Generally, the pipeline sensitivity leak test is applicable in the following situations: 1. Newly installed pipeline systems or those that have undergone major modifications. 2. Piping systems in pipeline stations and plant buildings. 3. Hazardous pipeline systems such as those involving high pressure, high temperature, toxicity, or flammability. 4. Pipeline systems that need to comply with regulations and standards. Currently, in China, the relevant standard specifications for reference include: 1. The Ministry of Construction’s \"Code for Construction and Quality Inspection of Building Water Supply and Drainage Projects\"; 2. GB/T 14298-2013 \"Technical Specifications for Ventilation and Pollution Control in Underground Utility Tunnels\"; 3. CJ/T 446-2017 \"Rules for Hydrostatic Testing of Pressure Pipelines in Operating Petrochemical Plants\"; 4. SY/T 0519-2008 \"Code for Construction and Acceptance of Pipelines in the Oil and Gas Industry\". The above standards are provided for reference only, and the appropriate one should be selected based on actual circumstances. At the same time, it is also necessary to strictly adhere to the standard requirements during the testing process, and take necessary measures to ensure the safety of the tests. .

It is described in more detail in SH/T 3501-2021.
