ASME B16.23-2011 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 (DWV) systems. These fittings are designed for use 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 ANSI/ASME B1.20.1.
This Standard is allied with ASME 816.29, 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
(6) pitch (slope)
(c) abbreviations for end Connections
(d) sizes and methods for designing openings for reducing fittings
(e) marking
(fl material
t’g) dimensions and tolerances
2.1 Relevant Units
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 US. 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.
2.2 References
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.
2.3 Quality Systems
Requirements relating to the product manufacturer’s quality system programs are described in Nonmandatory Appendix A.
(a) These fittings arc designed for drainage and 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.
(h) Ilie 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).ASME B16.23 pdf free download.
