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,
