ASME B16.50:2001 pdf download.WROUGHT COPPERAND COPPER ALLOY BRAZE-JOINT PRESSURE FITTINGS.

9.2 Ovality of Fining End (C or FTG)

Maximum ovality of the titling bra c-joint end shall not exceed l of the maximum diameters shown in Table 3 (Table 13). The aserage of the maximum and minimum diameters shall be within the dimensions shown in the table.

9.3 Inside Diameter of Fitting

The minimum cross-sectional area of the inside diameta through the fitting body shall not he less than the theoretical minimum area delined by diameter ‘0” in Table 3 (Table 13). The out-of-rnundnes condition of the cross-sectional area shalt not exceed the

value shown in Table 3 (Table 13).

For reducer or adapter fittings, the smallest end diameter shall apply. provided that this diameter does not restrict the other

outlets.

9.4 Wall Thickness

The minimum wall-thickness shall not he less than shown in Table 3 (Table I)).

10 THREADED ENDS

Fitting threads shall he right-hand, conforming to ASME H 1.20.1. American National Standard for Pipe Threads. General Purpose

(Inch). They shall he taper threads I Nvr).

10.1 CountersInk or Chamfer

All internal threads shall he 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 he chamfered at an angle of 30 deg to 45 deg from the axis.

Countersinking and chamfering shall be concentric with the threads.

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