Does anyone know how far a 1/2" MNPT will thread into a 1/2 FNPSM when it is hand tight? (note: this arrangement is typical of bi-metal thermometers threaded into thermowells.) I can't find a chart/table which shows this information. I could just try it, but I do not have the parts.
Should one always drill the hole in the main pipe run such that the diameter of the hole is the same as the diameter of the S-O-L on the saddle end, regardless of the diamter of the branch line? I have been told that this is the standard method to ensure a full-pen weld is achieved. For...
Is the non-recoverable DP for an eccentric orifice the same for a concentric orifice when the orifice bore is the same for both types? If not, is there a published relationship to determine the equivalent bore of an eccentric orifice to result in the same non-recoverable loss as the concentric...
