10.3 Design of Threaded Ends

The wrenchrng section of internally threaded ends shall be polygonal or bead with or without ribs, and the wrenching section of

externally threaded ends shall be furnished with polygon, ribs, or flats, at the manufacturer’s option.

11 ALIGNMENT

The maximum allowable deviation in the angular alignment of any end from the specified axis position shall be deg (1 deg total).

See Figure 11-1.

12 GAGING

121 Preferred Gaging Method of Solder-joint Ends

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

gages designed to hold the product within the limits established In Table 3.1,1-1. Gage tolerances shall be Class ZM. as defined in ASME 114.4M.

12.2 OptionaL Gaging Method of SoLder-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 pat-a. 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 K1.20.1.

NOTE: In gaging pipe threads, it is acceptable and common pt-ac0cc to rap or tap the part to ensure proper seattng of the gage.

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

and other foreign materials.
