ASME B16.22:2012 pdf download.Wrought Copper and Copper Alloy Solder-Joint Pressure Fittings.

The largest opening in the fitting shall govern the tolerance to be applied to all openings.

9.3 Ovallty of Fitting End (C or FTG)

Maximum ocality of the fitting solder-joint end shall not exceed 1% of the maximum diameters shown in Table 1 (Table Il-I). The

average of the maximum and minimum diameters shall be within the dimensions shown in the Table.

9.4 Inside Diameter of Fitting

The minimum cross-sectional area of the inside diameter through the fitting body shall not be less than the theoretical minimum

area defined by diameter 0 in Table I (Table li-i). The out-of-roundness condition of the cross-sectional ansi shall not exceed the value shown in Table I (Table Il-I).

For reducer or adapter fittings, the smallest end diameter shall appl pmvided that this diameter does not restrict the other

outlets.

93 Wall Thickness

The minimum wall thickness shall not be less than that shown in Table I (Table Il-i).

10 ThREADED ENDS

Fitting threads shall be right-hand, conforming to ASMF BI.20.I. They shall be taper threads (Nl’T).

10.1 CountersInk or Chamfer

All internal threads shall be countersunk a distance no less than one-half the pitch of the thread, at an angle of approximately

45 deg with the axis of the thread. All external threads shall be chamfered at an angle of 31) deg to 45 dcg from the axis. Countersinking and chamfering shall be concentric with the threads.

The length of threads shall be measured to include the countersink or chainfer.
