RE: SUCTION STRAINERS
Seriously, If you plan to leave the strainer in, install pressure taps so you can measure the delta P and know if it is clogged.
If you are really confident that you've done a good job of cleaning pipe, you can go without the pressure taps and remove the screen at your earliest opportunity after startup.
We've run years with some of these screens in place. At 200 percent area, pressure drop isn't a problem unless they clog, which is of course why they are there in the first place !
RE: SUCTION STRAINERS
DR recommends installing temporary strainers on the inlet to their centrifugal compressors and leaving them in for one year.

RE: SUCTION STRAINERS
Whenever you suspect the entrance of dirt, use a strainer. If you are pumping from a tank you might catch some rags.
If you are using foam pigs to clean your pipe lines, be sure to mount a strainer in the suction.
Whenever pumps start cavitating, is noisy or vibrating heavily, check the strainer first.
