ASME B16.24 pdf download CAST COPPER ALLOY PIPE FLANGES AND FLANGED FITTINGS: CLASSES 150, 300, 400, 600, 900, 1500, AND 2500
1 GENERAL
1.1 Scope
This Standard for cast copper alloy pipe flanges and flanged fittings covers:
(a) pressure temperature ratings;
(b) sizes and methods of designating openings for reduced fittings;
(c) marking;
(d) materials;
(e) dimensions;
(f) bolts, nuts, and gaskets;
(g) tolerances; and
(h) tests.
1.2 Codes and Regulations
A flange or flanged fitting used under the jurisdiction of the ASME Boiler and Pressure Vessel Code, the ASME Code for Pressure Piping, or a governmental regulation is subject to any limitation of that code or regulation. This includes any maximum temperature limitation, or rule governing the use of a material at low temperature, or provisions for operating at a pressure exceeding the pressure-temperature ratings in this Standard.
1.3 Units of Measurement
U.S. customary units are the standard. For conversion to metric units, use the following:
(a) 1 in. p 25.4 mm
(b) 1 psi p 0.069 bar p 6.9 kPa
(c) °F p 1.8°C + 32
1.4 Quality Systems
Requirements relating to the product manufacturer’s quality system programs are described in Nonmandatory Appendix A.
2 PRESSURE-TEMPERATURE RATINGS 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 to the materials designated in para. 5.2.3 and to the dimensions prescribed in ASME B16.5. 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 fitting. In general, this temperature is the same as that of the contained fluid.
