Requirements for pneumatic testing of pressure pipelines
Thread Content
For pressure pipeline construction, once it is completed, instead of conducting a hydraulic test, an air test is carried out. What are the specific requirements?
For certain special pipelines for which hydraulic testing is indeed not feasible, when the design pressure is greater than 0.6 Mpa, the design unit must specify in the construction design documentation which pipelines are affected, and must also outline the methods and procedures for pneumatic testing so that the construction party can carry out the work accordingly.
I’m not sure if it’s a long-distance pipeline; if so, please refer to Article 14.4 of the \"Code for Construction and Acceptance of Oil and Gas Long-Distance Pipeline Projects\"
