What kind of strainer are you using that you think a spacer ring can replace it?

Strainers are necessary components for proper operation of pumps and compressors, why temporary only during
commissioning? What alien station is this installation located at?

Hello everybody
Temporary strainers are specified on piping connected to pumps and compressors during commissioning.They are placed between two flanges, so there is a gasket specified on both sides of the strainer.If the thickness of the strainer plate is 't' mm , then the total space between the two flanges is (6 + t )mm .(taking gasket thickness = 3mm ).The same is reflected on the isometrics.

Now , after commissioning , when this strainer is removed , how is the gap created by removal of the strainer ( 3+t )mm compensated for ?

Is a spacer ring of thickness 't' installed in place of the strainer.? If this is not the case , then strain is being imposed on the equipment nozzle for which there is no accounting during stress analysis.

Regards,
