Oriface Flowmeters relation to Pipe Class.
Oriface Flowmeters relation to Pipe Class.
(OP)
Hi guys,
Flowmetering is new to me. I come acroos my company standard document, and it stated that for an oriface plate, is shall be ANSI 300 as minimum.
According to that, if the pipeline is using ANSI 150 pounds, but the oriface plate still need to be ANSI 300. Any technical reason for that?
all that i'm aware is that the bore will be according to the pipe diameter.
Really appriciate your help.
Thanks guys,
:)

Less than that the Pipe Taps would be too close to the flanges.

No it won't, you need to specify the correct connection.
Good catch.

API MPMS 14.3.1 reflects the flange taps as a pair of tap holes positioned with the upstream tap center located 1 inch (25.4 millimeters) upstream of the nearest plate face and the downstream tap center located 1 inch (25.4 millimeters) downstream of the nearest plate face.
