API 610 NPSHr
API 610 NPSHr
(OP)
Hi Guys,
our cd seems to be corrupted. I need to check if API 610 requirement for NPSH testing (4.3.4.1.3) talks about checking the pressure at 3% head drop or something else?
thanks in advance...

RE: API 610 NPSHr
I have made many CDs work however by first rinsing them with water but do not touch the CD while rinsing. Then I put on hand soap with no abrasives and scrub the bugger hard with my fingers, then rinse again really hard with water no touchy and tamp dry with paper towels no rubbing.
