Specifications regarding the division of pressure testing sections for process pipelines
Thread Content
Hello, Sea Friends! Does anyone know which is the specification for dividing pressure testing sections in process pipelines? Please share, thanks!
It seems there are no standards or principles; just one pressure rating, for the same medium and the same material
It’s not necessarily the case, right? It should be possible to conduct pressure tests simultaneously as long as the test pressures are the same and the requirements for the medium are identical ； For fiberglass/CPVC, pressure testing can be carried out together with carbon steel or stainless steel, as well as alloys, as long as the test pressure and the test medium (fresh water, treated fresh water, or seawater) are the same ； For carbon steel, there are ordinary carbon steel, high-quality carbon steel, low-temperature carbon steel, etc.; it is acceptable as long as the test pressure and the test medium (gas, treated fresh water, or seawater) are the same ； For non-carbon steel pipes such as stainless steel, copper-nickel/nickel-based ferroalloys, and titanium alloys, it is acceptable as long as the test pressure and the test medium (gas, treated fresh water, or seawater) are the same.
