Can 80 bar differential pressure cause any problems while or after opening the valve, if WP is 345 bar? Can it damage the seats, will valve leak in future? We have limitations for depressurising across valve. If valves are 5000 psi rated then aren't they capable to handle 80 bars? How...
Thanks for that update. So as i understand this lands up on the visual examination for any distortion. Don't we need more confirmation than the visual inspection? Or should we say for example if it passes Hydro test without the leak, It is fit to use in service.
What are the adverse effects on material, if equipment is pressure tested at twice the rated pressure by mistake. Is it advisable to do any NDTs to see the condition of the material?
