MSS STANDARD PRACTICE SP-72 i This MSS Standard Practice was developed under the consensus of the MSS Technical Committee 401 and the MSS Coordinating Committee. The content of this Standard Practi
3、ce is the resulting efforts of competent and experienced volunteers 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
4、user, and the general public. The existence of an MSS Standard Practice 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, s
5、pecification, sales contract, or public law, as applicable. MSS has 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
6、the responsibility of the certifier or maker of the statement. “Unless 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
7、Practice (see Annex A). This Standard Practice shall remain silent on 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 an
8、y potential claim(s) or of any patent rights in connection therewith. 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. In this Standard P
9、ractice, all text, notes, annexes, tables, figures, and references are construed to be essential to the understanding of the message of the standard, and are considered normative unless indicated as “supplemental”. All appendices, if included, that appear in this document are construed as “supplemen
10、tal”. Note that supplemental information does not include mandatory requirements. U.S. customary units in this Standard Practice are the standard; (SI) metric units are for reference only. Substantive changes identified in the 2010 edition are “flagged” by parallel bars, as shown on the margins of t
11、his paragraph, and included within this 2010a edition. The specific detail of the change may be determined by comparing the material flagged with that in the previous edition. Specific changes and corrections between the 2010 and 2010a editions are indicated in the Forward. Non-toleranced dimensions
12、 in this Standard Practice are nominal unless otherwise specified. Excerpts of this Standard Practice may be quoted with permission.

Metric data (DN) and (PN) was added to Sections 1.3, 3.1.1, 5.2.2.1, 7.1.3, 7.1.4, 7.2.2, 7.2.3, and Table 1. T
16、he formulas in Sections 7.1.4 and 7.2.2 was revised to agree with MSS IS-9 formatting. The reference to NPS was corrected in all applicable Sections. Annex A listing all referenced standards documents was added. The 2010 Edition of MSS SP-72 was substantively updated from the 1999 Edition by primari
17、ly revising material in Section 7.2.4. The Pressure Number “PN” reference data was deleted in the 2010 edition (Sections 5.2.2.1, 5.2.2.2, and 7.1.4) as ASME no longer makes a soft conversion between class designations and PN. In addition, the Annex A listing of all referenced standards documents ha
18、s been updated. This 2010a Edition of MSS SP-72 replaces the 2010 Edition. The 2010a Edition of MSS SP-72 updates the obsolete 2010 Edition by: (1) the re-inclusion (from previous editions) of Section 3.1.2 and the first sentence of Section 5.3.1; (2) additional descriptive notes were inserted in Se
19、ctions 7.1.4 and 7.2.2; (3) the equation in Section 7.2.4.3 was clarified; (4) corrected the definition of “MYS1” in Section 7.1.4 and “AYS2” in Section 7.1.4; (5) corrected the definition of “AYS5” and “AYS6” in Section 7.2.2; and (6) additional editorial and conforming corrections. The corrections
20、 and changes mentioned in this paragraph are not “flagged” in the body of this text in order to preserve the substantive changes from the 1999 Edition that were identified in the original 2010 Edition.

22、ARD PRACTICE SP-72 1 1. SCOPE 1.1 This Standard Practice covers flanged or Butt-weld end ball valves having in general, but not restricted to, round openings which may be full port, regular port, or reduced port types. The following characteristics shall be considered standard practice unless otherw
23、ise specified by agreement between manufacturer and purchaser. 1.2 Valves covered by this Standard Practice are suitable for use in general liquid and gas service. Their service pressures and temperatures generally conform to standards cited in Section 2, but may be restricted by the materials used
24、for their seats and seals, or by other special considerations. 1.3 The size range covered by this Standard Practice is NPS 1/2 (DN 15) through NPS 36 (DN 900). 1.4 This Standard Practice covers ball valves of the following materials: Carbon Steel Alloy Steels Stainless Steels Ductile Iron Gray Iron
25、Copper Alloy 1.5 Names of common valve body types are given in Figure 1. When variations or other body types are used, they may be named by the manufacturer. The names of basic valve parts are given in Figure 2. Other parts may be named by the manufacturer. Body types and valve parts may also be ide
26、ntified by applicable MSS or other terminology standards. 2. SERVICE PRESSURE RATINGS 2.1 The pressure-temperature rating of flanged and Butt-welding end ball valves shall conform to those set forth in the Standards listed within this section, except as they are limited by their seat and seal materi
