Is there a standard stating that for non-pressure pipelines, hydraulic testing is not required, and only a gas-tightness test is needed?
Yes, some specifications or standards require that non-pressure pipelines undergo only a gas-tightness test rather than a hydrostatic test. This mainly depends on the design requirements and operating conditions of the pipeline. Generally, a gas-tightness test is sufficient to prove the sealing performance of non-pressure pipelines. However, specific implementation should follow relevant industry standards or specifications. .
The airtightness test is used to check the tightness of pipes and detect any leaks； A hydrostatic test, also known as a strength test, is primarily used to examine the strength of pipes (their pressure resistance). Therefore, non-pressure pipelines should have their need for strength testing determined based on their usage conditions and design requirements.
By non-pressure pipes, you mean pipes that are not subject to pressure, pipes that rely on gravity for flow； Does it still refer to pressure pipelines of special equipment? ； In the case of the first type, a strength pressure test is not required ； In the case of the second type, different design and acceptance standards are established depending on the type
