ASME B16.22:2001 pdf free download.WROUGHT COPPER AND COPPER ALLOY SOLDER JOINT PRESSURE FTTINGS.
(b) Other coppers and copper alloys are permitted. provided they meet the chemical requirement. of 84% minimum copper and 16% maximum ,inc. and provided the linings produced from the opper alloy meet all the mechanical and corrosion-resistant properties for the end purposes of the fittings. The compositico of the copper alloy shall contain nothing that will inhibit joining to the tube or to other fittings.
7 LAYING LENGTHS
Due to widely varying manufacturing processes. mcaniiigful laying length requircnicnts ot fittings cannot be established. Consult the manufacturer for these dimensions.
8 TUBE STOPS
Except for repair couplings fittings shall be manufacturcd with a tube stop. couplings shall not require a tube stop. The tube stop shall control joint lenth. even with an external FTGt end having the minimum outside diameter shown in Table 3 (Table 113) Examples of various tube stop conliguranons are shown in Fig. 2.
9 INSPECTION TOLERANCE
9.1 Linear Dimensions
An in%peclion tolerance. as shown in Table 2 (Table 112). shall be allowcd on center-to-shoulder. cCntcr-tocenter, center-to-threaded-end, and shoulder-to- threaded-end dimensions on all fittings having internal (C) solder ends, as well as on center-to-solder-end and sokier end-to-threaded-end dimensions on all hitings having external (FIG) solder ends.
Coupling inspection limits for shoulder-to-shoulder and shoulder-lu-end dimensions shall he double those shown in Table 2 tTahlc 112). except that the minus tolerance applied to dimension L (see Fig. 1) shall not result in a dimension less than 1.5 mm IO.OtI in.).
The largest opening in the fitting shall govern the tolerance to he applied to all openings.
9.2 Ovality of Fitting End (C or FIG)
Maximum ovality of the lining solder-joint end shall not exceed l’ of the maximum diameters shown in Table 3 (Table 113). The aselage 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 diameter through the fitting body shall not be less than the theoretical minimum area defined by diameter 0 in Table 3 Table 113).
