4、 and the MSS Coordinating Committee. The content of this Standard Practice is the result of the efforts of competent and concerned volunteers to provide an effective, clear, and non-exclusive specification that will benefit the industry as a whole. This MSS-Standard Practice is intended as a basis f
5、or common practice by the manufacturer, the user, and the general public. The existenceof an MSS Standard Practice does not in itself preclude the manufac- ture, sale, or use of products not conforming to the Standard Practice. Mandatory conformance is established only by reference in a code, specif
6、ication, sales contract, or public law, as applicable. Unless otherwise specifically noted in this MSS SP, any standard referred to herein is identified by the date of issue that was applicable to the referenced standard(s) at the date of issue of this MSS SP.

The specific detail of the change may be determined by comparing the material flagged with that in the previous edition.

PURPOSE Flanges specified in the Sta
14、ndard Practice should be used only with the lens gasket specified herein. This Standardpractceissimilarin intenttoASMEB16.5, but governs a higher pressure class and lens gasket connection. At the time of writing this Standad Prac- tice, no American Standard existed for pipe wails as heavy as require
15、 for this pressure class. Most such piping is done with seamless steel tubing. However, for purposes of flange and stub standardization, a definite set of outside diameters has been specified. sizes such as given in ASME B36.10M insofar as the relationship between size and outside diameter is concer
16、ned. These flange and stub dimensions have been calculated on the basis of the attached pipe wall tabulation covering a class of pipe which could be called Sch-dule 500, shown in Table 4. It is rec- ognized that most tubing used in this high pressure field will not correspond to these tabulated pipe
17、 di- ameters. However, transition pieces, transitional welds, or turning down the pipe should readily permit the use of these standard flanges and stubs. I I 4. MARKING 1. SCOPE Flanges shall be marked in accordance with MSS sp-25 except rating designation shall be “4000 SP- 65”. This Standard Pract
18、ice establishes requirements for cast and forged steel flanges (welding neck and pecially for use i n the chemical industry with end 5. UTERIALS straight threade) and threaded stubs designed es- I I connections making use of lens gaskets. 2. PRESSURE RATING 2.1 For reference purposes the material co
19、vered in this standard shall be identified as 4000 SP-65. Pressure ratings applicable to any of the materials idenMid in Section 5 are given in Table 2 in custom- ary units. 2.2 The reference temperature is the metal tem- perature and in general this is the same as the tem- perature of the contained
20、 fluid. U s e of a pressure rating correspondmg t o a temperature other than that of the conained fluid is the responsibility of the user, subject to the requirements of applicable codes and standards. 3. SIZE The size used throughout this Standard Practice is nominal pipe SUR. This is based on stan
21、dard pipe 5.1 CeRerai This Standard Practice is based on forged and cast steel flange material as produced under various ASTM specifications for pressure pip ing work. 5.2 Forged and Cast Materiais Acceptable flange materials shall be forged or cast Group 1 and Group 2 product forms listed in Table
22、lA, ASME B16.5, except those low carbon grades of stainless steel that are listed under Group 2.3 of Table 1A shall not be used. The notes of Table 1A and Table 2, ASME B 16.5, applicable to the listed material, also apply. 5.3 Gasket Maerak The lens gasket material shall be soft iron, unless limita
23、tions of temperature or corrosion resistance require another material be se- lected. The selected gasket material shall have a chemical composition and corrosion resistance com- patible with the flange material. See Table 1 for gasket materials and hardness limits. 1 Copyright MSS Provided by IHS un
