2、dardsmss-hq.org MSS www.mss-hq.org MSS STANDARD PRACTICE SP-109 i This MSS Standard Practice was developed under the consensus of the MSS Technical Committee 201 and the MSS Coordinating Committee. The content of this Standard Practice is the resulting efforts of competent and experienced volunteers
3、 to provide an effective, clear, and non-exclusive standard that will benefit the industry as a whole. This MSS Standard Practice describes minimal requirements and is intended as a basis for common practice by the manufacturer, the user, and the general public. The existence of an MSS Standard Prac
4、tice does not in itself preclude the manufacture, sale, or use of products not conforming to the Standard Practice. Mandatory conformance to this Standard Practice is established only by reference in other documents such as a code, specification, sales contract, or public law, as applicable. MSS has
5、 no power, nor does it undertake to enforce or certify compliance with this document. Any certification or other statement of compliance with the requirements of this Standard Practice shall not be attributable to MSS and is solely the responsibility of the certifier or maker of the statement. “Unle
6、ss indicated otherwise within this MSS Standard Practice, other standards documents referenced to herein are identified by the date of issue that was applicable to this Standard Practice at the date of approval of this MSS Standard Practice (see Annex C). This Standard Practice shall remain silent o
7、n the validity of those other standards of prior or subsequent dates of issue even though applicable provisions may not have changed.” By publication of this Standard Practice, no position is taken with respect to the validity of any potential claim(s) or of any patent rights in connection therewith
8、. MSS shall not be held responsible for identifying any patent rights. Users are expressly advised that determination of patent rights and the risk of infringement of such rights are entirely their responsibility.

10、requirements. Substantive changes in this 2012 edition are “flagged” by parallel bars as shown on the margins of this paragraph. The specific detail of the change may be determined by comparing the material flagged with that in the previous edition. Non-toleranced dimensions in the Standard Practice

It does not include requirements for weld-fabricated fittings. The purpose of this Standard Practice is to provide indus
15、try with a standard for factory-made, weld-fabricated, copper pressure fittings in nominal sizes 1/4 through 12. This Standard Practice follows ASME B16.22, modified as required. Dimensions within this Standard Practice utilize U.S. customary units. Guidelines for (SI) metric data conversion may be

SCOPE This Standard Practice covers factory-made, weld-fabricated, copper pressure fittings in nominal sizes 1/4 through 12. Included in this Standard Practice are: a) Pressure-temperature rat
19、ings b) Abbreviations for end connections c) Size and method of designating openings of fittings d) Marking e) Material f) Weld specifications g) Laying lengths h) Inspection tolerance i) Alignment j) Tests k) Gaging 2. PRESSURE-TEMPERATURE RATINGS 2.1 Rating of Fitting The rated internal working pr
20、essure-temperature rating for a solder-joint fitting is dependent upon not only fitting and tube strength, but also composition of the solder or braze alloy used for the joint. Pressure-temperature ratings for solder joints, to the dimensions of Table 3 and made with typical commercial solders or br
21、aze alloys, are specified in Annex A. The system rated internal working pressure shall be the lower of the values shown in Table 1 and Annex A. 2.2 Bursting Strength Fittings fabricated to this Standard Practice shall have an ambient temperature bursting strength of at least four times the 100 F rat
22、ed internal working pressure, as detailed in Table 1. 3. FITTING END DESIGNATIONS The following symbols are used to designate the type of fitting end: Symbol Definition C = Solder-joint fittings end made to receive copper tube diameter (female) FTG = Solder-joint fitting end made to copper tube diam
23、eter (male) 4. SIZE The size of the fittings detailed in Table 3 corresponds to standard water tube sizes, as designated in ASTM B88. Fittings are designated by the size of the openings in the sequence illustrated in Figure 1. 5. MARKING Each fitting shall be permanently marked with the manufacturer
24、s name or trademark in accordance with MSS SP-25. Marking may be omitted from any fitting where it may damage soldering surfaces. 6. MATERIAL a) The standard material is UNS No. C12200. b) The use of a material other than copper UNS No. C12200 is the responsibility of the user. c) Component parts sh
25、all be joined by weld materials meeting the requirements of AWS A5.7/A5.7M. 7. LAYING LENGTHS Consult the manufacturer for dimensions. WELD-FABRICATED COPPER SOLDER-JOINT PRESSURE FITTINGS MSS STANDARD PRACTICE SP-109 2 8. INSPECTION TOLERANCE 8.1 Linear Dimensions An inspection tolerance, as shown
26、in Table 2, shall be allowed on center-to-shoulder, and center-to-center on all fittings having female solder (solder-cup) ends, and on center-to-solder ends and dimensions on all fittings having male solder (fitting) ends. Coupling inspection limits for shoulder-to-shoulder and shoulder-to-end dime
27、nsions shall be double than those indicated in Table 2. The largest opening in the fitting governs the tolerance to be applied to all openings. 8.2 Ovality Maximum ovality shall not exceed 1% of the maximum diameters specified in Table 3. The average of the maximum and minimum diameters must be with
28、in the dimensions indicated in Table 3.

TEST These fittings shall be tested at a gage air pressure of 60 psi minimum while under water or at a hydrostatic gage pressure of 250 psi, for a sufficient length of time, to assure tightness. 11. GAGING 11.1 Standard Gaging Method for Solder- Joint Ends The standard method of g
33、aging the diameter tolerances for male and female ends shall be by the use of plain plug and ring gages designed to hold the product within the limits established in Table 3. 11.2 Optional Gaging Method for Solder- Joint Ends For gaging the diameter tolerances for male and female ends, the manufactu
34、rer may use direct reading instruments instead of ring and plug gages as specified in Section 11.1. When gaging the diameter of male and female ends, using direct reading instruments, refer to Section 8.2. MSS STANDARD PRACTICE SP-109 4 NOTES: (a) Fittings are designed by size in the order: 1 x 2 x
