Guangzhou Ailixun Electronic Technology Co., Ltd. and Ailixun Testing Equipment (Ningbo) Co., Ltd. provide the main testing standards and corresponding standard numbers for pipeline pressure detection and related

pipeline pressures, covering international, regional (such as China, the European Union, and the United States), and industry standards

Pipeline pressure testing is an important means of testing the strength, sealing, and safety of pipeline systems, and the testing standards vary 

depending on the application field and medium (such as water, gas, oil, etc.). 

The following are common international and domestic standards and key points:

key parameter

-Test pressure:

-Hydraulic test: usually 1.5 times the design pressure (for pipelines at room temperature).   

-Air pressure test: 1.1-1.5 times the design pressure (considering safety risks).   

-Pressure holding time: generally ≥ 10 minutes, according to standards or design requirements.   

-Qualification criteria: no visible leakage, pressure drop ≤ 1% test pressure (or as required by specifications).
