What standards must the gas used for pressure pipeline pneumatic testing meet?
Thread Content
I would like to ask: where can I find out the standards that the gas must meet when a pipeline is to undergo a pressure test? Or what standards do gas compressors need to meet? If you know anything, please let me know. Thank you very much.
For pipeline pressure testing, dry air or nitrogen should be used; refer to the acceptance criteria for pressure vessels and pipelines.
The test pressure is too high; pneumatic testing cannot be used. Check the relevant standards – it seems that the pressure should not exceed 0.6 MPa.
The gas should be oil-free and water-free compressed air or nitrogen; steam should be used for steam pipelines, while non-steam pipelines should not be purged with steam
Please refer to the design specification. The design specifications will outline the construction standards for pipeline installation and testing.
