ASME B16-22-2012 pdf free.Wrought Copper and Copper Alloy Solder-Joint Pressure Fittings.
ASME B16-22 establishes specifications for wrought copper and wrought copper alloy, solder-ioint, seamless fittings, designed for use with seamless copper tube conforming to ASTM 888 (water and general plumbing systems), 8280 (air conditioning and refrigeration service), and 8819 (medical gas systems), as well as fittings intended to be assembled with soldering materials conforming to ASTM B32, brazing materials conforming to AWS A5.8, or with tapered pipe thread conforming to
ASME B1.20.1.
This Standard is allied with ASME 816.18, which covers cast copper alloy pressure fittings. It provides requirements for fitting ends suitable for soldering. This Standard covers the following:
(a) pressure—temperature ratings
(b) abbreviations for end connections
(c) size and method of designating openings of fittings
(d) marking
(e) material
(f) dimensions and tolerances
(g) tests
2.1 UnIts of Measure
The values stated in either SI (metric) or U.S. Customary (in.-Ib) units of measure shall be regarded separately as standard. Within the main text, SI units are given. For convenience, the customary units are shown in Mandatory Appendix II. Ihe values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other.
NOTE: Combining values from the two sys4ems may result in nonconformance with the Standard,
2.2 References
Standards and specifications adopted by reference in this Standard are shown in Mandatory Appendix Ill 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 111.
2.3 Quality Systems
Requirements relating to the product manufacturer’s quality system program are described in Nonmandatory Appendix B
3.1 Rating of Fittings and Joints
The internal pressure—temperature rating for a solder- joint system is dependent upon not only fitting and tube strength, but also composition of the solder used for the joint and selection of valves and appurtenances.
3.1.1 Solder Joints. Pressure—temperature ratings for solder joints to the dimensions of Table I (Table 11-I), made with typical commercial solders, are given in Table I-I (Table 11-4).
The internal pressure—temperature rating of the system with solder joints shall be the lowest of the values shown in Table 2 (Table 11-2) and Table I-I (Table 11-4) and those of the tube, valves, and appurtenances.
3.1.2 Braze Joints. Pressure—temperature ratings for braze joints to the dimensions of Table 1 (Table li-I), made with typical commercial brazing materials, shall be considered equal to the values given in Table 2 (Table 11-2).
The internal pressure—temperature rating of the system with braze joints shall be the lowest of the values shown in Table 2 (Table 11-2) and those of the tube, values, and appurtenances.
3.2 Bursting Strength
Fittings manufactured to the Standard shall have an ambient temperature bursting strength of at least four times the 38°C (100°F) internal pressure rating as shown in Table 2 (Table 11-2).
4.1 Size
The size of the fittings shown in Table 1 (Table Il-I) corresponds to standard water tube size as shown in ASTM B88. The size of the threaded ends corresponds to nominal pipe size as shown in ASME B1.20.1.
Fittings are designated by the size of the openings in the sequence illustrated in Fig. 1.ASME B16-22 pdf download.
