I am writing to inquire about the strainers on the suction side of centrifugal pumps. My question is when they are mandated to be installed? Is there an international standard that specifies that (e.g. API)?

In my experience so far, the client has always decided if he wants a strainer or not, usually based on experience with a pump in a similar service.

Thanks for the reply.

My service is reduced crude from the bottom of main CDU Column. I know this service is fouling and many companies require strainers in such service (e.g. ExxonMobil). However, my client don't think it is required.

Hi Vegeta.

One question: is your client an expert in CDU operations?

My guess is: NO.

Good luck!

I have no idea about that because my communication with them is through one to three persons only.

Bobby Strain,

It is to run hydraulics for future revamp due to capacity increase and to provide any necessary recommendations.
