Is there a specified maintenance cycle for standard orifice plates?

What is the maintenance cycle for standard orifice plates? Orifice plates (whether they are deformed or worn, gaskets, pressure tapping holes, etc.) – do you colleagues have any explicit regulations or standard requirements in your companies regarding these? If available, please send one to me. Thank you. Email: 24266365@qq.com

You can take a look at JJG 640-1994, the Calibration Regulations for Differential Pressure Flow Meters; it contains the relevant requirements and is available for download online.
