ASME B16.50:2018 pdf download.Wrought Copperand Copper Alloy Braze-Joint Pressure Fittings.

The maximum allowable deviation In the angular alignment olany end from the specified axis position shall be 4 deg (1 deg total)

(see Figure 11-1).

12 GAGING

121 Preferred Gaging Method of Braze-Joint Ends

The preferred method olgaging the diameter tolerances for external and Internal ends shall be by the use of plain plug and ring

gages designed to hold the product within the limits established In Table 3.1-1. Gage tolerances shall be Class ZM. as defined In

ANSI B4,4M.

12.2 OptionaL Gaging Method of Braze-Joint Ends

For gaging the diameter tolerance of external and internal ends, the use of direct reading instruments instead of ring and plug

gages as specified in para 12.1 shall be permitted. When gaging the diameters of external and internal ends using direct reading

instruments. refer to para. 9.3.

12.3 Standard Gaging Method of Threaded Ends

The standard method of gaging the externally and internally threaded ends shall be in accordance with the requIrements of ASME B1,20,1.

NOTE: In gaging pipe threads. It is aceeptahle and common practice to rap or tap the part to ensure proper seating of the gage

However, it is first necessary to clean both the gage and product threads to ensure that they are free olchips. burrs. abrasives,

or other foreign materials.
