ASME B16.23-2016 pdf free.CAST COPPER ALLOY SOLDER JOINT DRAINAGE FITTINGS: DWV.
ASME B16.23 establishes specifications for cast copper alloy solder joint drainage fittings, designed for use in drain, waste, and vent (l)WV) systems. These fittings are designed for USC with seamless copper tube conforming to ASTM 8306, Copper Drainage Tube (DWV), as well as fittings intended to be assembled with soldering materials conforming to ASTM B32, or tapered pipe thread conforming to ASME B1.20.1.
This Standard is allied with ASME B16.29, Wrought Copper and Wrought Copper Alloy Solder Joint Drainage Fittings — DWV.
It provides requirements for fitting ends suitable for soldering. This Standard covers
(a) description
(b) pitch (slope)
(c) abbreviations for end connections
(d) sizes and methods for designing openings for reducing fittings
(e) marking
(f) material
(g) dimensions and tolerances
This Standard states values in both SI (Metric) and U.S. Customary units. These systems of units are to be regarded separately as standard. Within the text, the U.S. Customary units are shown in parentheses or in separate tables that appear in Mandatory Appendix I. The values stated in each system are not exact equivalents; therefore, it is required that each system of units be used independently of the other. Combining values from the two systems constitutes nonconformance with the Standard.
Standards and specifications adopted by reference in this Standard are shown in Mandatory Appendix II, which is part of this Standard. It is not considered practical to identify the specific edition of each standard and specification in the individual references. Instead, the specific edition reference is identified in Mandatory Appendix II.
Requirements relating to the product manufacturer’s quality system programs are described in Nonmandatory Appendix A.
3 DESCRIPTION
(a) These fittings are designed for drainage ind vent systems using the solder joint method of connection. The fitting cups (C), are provided with stops so that the ends of the tube, when assembled, meet the stops, thereby Forming essentially smooth passageways.
(b) The sketches and designs of fittings are illustrative only. The dimensions specified herein shall govern in all cases.
All nominal 90-deg fittings shall be pitched to result in a slope of 21 mm/rn (0.25 in./ft) (2.1%) of length of horizontal tube with reference to a horizontal plane (see Fig. 1).
The following symbols are used to designate the type of fitting end:
C = solder-joint fitting end made to receive copper tube diameter (female)
F = internal ANSI Standard taper pipe thread (female) Nl’T
FTG = solder-joint fitting end made to copper tube diameter (male)
M = external ANSI Standard taper pipe thread (male) NPT
NPSM = standard straight mechanical pipe thread Si = end of fitting made to receive O.D. tube size
(a) The size of the fittings scheduled in Tables 1 through 56 and Tables I-i through 1-56 corresponds to the drainage tube size shown in ASTM 13306. The size of the threaded ends (except slip joints) corresponds to the nominal pipe size.ASME B16.23 pdf download.
