Regarding the standards for maintenance work in the petrochemical industry and the application of control valves, I’m seeking advice from experts

2016-09-20View Original

Thread Content

For the 2009 version of the petrochemical maintenance quotas, how should the quotas be applied for the disassembly and maintenance of control valves during production shutdown? Should we use the procedures for removing flanged control valves outlined in Chapter 6 on demolition in Volume 3 on industrial pipelines, or those for removing control valves in conjunction with other components as described in Article 6 of Chapter 13 in Volume 5 on automation control and instrumentation? Can these two parameters be obtained simultaneously from the removed control valve? Please explain in detail
