2.1 General The tabulated pressure-temperature ratings shown in Tables 1 and 2 apply to the materials designated in paras.5.2.1, 5.2.2, 5.3.1, and 5.3.2, and to the dimen- sions prescribed in Tables 3, 4, 5, and 6. The tabulated pressure- temperature ratings shown in Table 1 apply o the materials designated in para. 5.2.3 and to the dimensions prescribed in ASME B 16.5. All ratings are independent of the contained fluid and are the maximum nonshock pressures at the tabulated temperatures. Pres- sure ratings at temperatures intermediate to those tabu- lated may be obtained by linear interpolation.
2.2 Ratings of Flanged Joints Ratings in this Standard apply to flanged joints, which conform to the limitations on bolting in paras. 5.4 and 8(a), and on gaskets in paras. 5.5 and 8(b), and which are made up in accordance with good practice for alignment and assembly. Use of the ratings for flanged joints not conforming to these limitations is the sole responsibility of the user. Requirements for alignment and assembly of joints and consideration of leakage due to forces and moments developed in the connected piping or equipment are not covered in this Standard. If the two flanges in a flanged joint do not have the same pressure- temperature ratings, the rating of the joint at any temperature is the lower of the two flange ratings at that temperature.
2.3 Rating Temperature The temperature shown for a corresponding pressure rating is the temperature of the pressure-containing shell of the flange or flanged ftting. In general, this temperature is the same as that of the contained fuid,Use of a pressure rating corresponding to a temperature other than that of the contained fluid is the responsibility of the user, subject to the applicable code or regulation. For any temperature below -20°F, the rating shall be no greater than the rating for -20F.
2.4 Low Temperature Service When assembled with suitable bolting and gaskets, and subject to the applicable code or regulations, copper alloy flanges and flanged ftings, in accordance with this Standard, may be used at temperatures down to – 325°F.
2.5 System Hydrostatic Test Flanged joints and flanged fttings may be subjected to system hydrostatic tests at pressures not to exceed 1.5 times the tabulated working pressure at 100^F. System testing at higher pressures is the responsibility of the user, subject to the requirements of the applicable code or regulations.
3 SIZE AND METHOD OF DESIGNATING OPENINGS 3.1 Regular Flanges or Fittings The size of a regular flange or ftting is identifed by the corresponding nominal pipe size (NPS). 3.2 Reduced Fittings Reduced fitings shall be designated by the size of the openings in their proper sequence as indicated in Fig. 1.
4 MARKING 4.1 General Except as modifed herein, flanges and flanged fttings shall be marked as required in MSS SP-25. 4.1.1 Name. The manufacturer’ s name or trademark shall be applied.
4.1.2 Material. All flanges and flanged fttings shall be marked with the ASTM specification number. In addition, the grade identification symbol “952″ is required for flanges cast to ASTM B 148. 4.1.3 Rating Class. Numerals shall be applied giving the pressure rating class for which the product is designed.
4.1.4 Designation. The designation “B16″ shall be applied, preferably located adjacent to the Class designation, to indicate conformance to this Standard.
4.1.5 Size. The nominal pipe size shall be applied but may be omitted from reducing flanges and reducing flanged fttings.ASME B16.24 pdf download.
