CAST COPPER ALLOY SOLDER JOINT
DRAINAGE FITTINGS: DWV
1 SCOPE
This Standard establishes specifications for cast cop-
per 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 conform-
ing to ASTM B306, 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 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
2 GENERAL
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
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 equiva-
lents; 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 practi-
cal 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.
3 DESCRIPTION
(a) These fittings are 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.
(b) The sketches and designs of fittings are illustrative
only. The dimensions specified herein shall govern in
all cases.
4 PITCH (SLOPE)
All nominal 90-deg fittings shall be pitched to result
in a slope of 21 mm/m (0.25 in./ft) (2.1%) of length of
horizontal tube with reference to a horizontal plane (see
Fig. 1).
5 ABBREVIATIONS
The following symbols are used to designate the type
of fitting end:
C p solder-joint fitting end made to receive
copper tube diameter (female)
F p internal ANSI Standard taper pipe thread
(female) NPT
FTG p solder-joint fitting end made to copper
tube diameter (male)
M p external ANSI Standard taper pipe thread
(male) NPT
NPSM p standard straight mechanical pipe thread
SJ p end of fitting made to receive O.D. tube
size
6 SIZE
(a) The size of the fittings scheduled in Tables 1
through 56 and Tables I-1 through I-56 corresponds to
the drainage tube size shown in ASTM B306. The size
of the threaded ends (except slip joints) corresponds to
the nominal pipe size.
