ASME B16.24-2011 pdf free.Cast Copper Alloy Pipe Flanges and Flanged Fittings.
ASME B16.24 covers cast copper alloy threaded-joint pipe flanges and blind pipe flanges having rating class designations 150, 300, 600, 900, 1500, and 2500. This Standard also covers flanged fittings having rating class designations 150 and 300. It establishes requirements for
(a) pressure—temperature ratings
(b) size and method of designating openings for reduced fittings
(c) markings
(d) materials
(c) dimensions
( bolting and gaskets
(g) tolerances
(h) tests
This Standard also provides dimensional requirements for flanged ends of valves conforming to MSS SP-80.
2.1 Relevant Units
This Standard states values in both SI (Metric) and U.S. Customary units, As an exception, diameters of bolts and flange bolt holes are expressed in U.S. Customary units only. These systems of units are to be regarded separately as standard. Within the text, the U.S. Customary units are shown in parentheses or in separate tables that appear in Mandatory Appendix I. The values stated in each system are not exact equivalents; therefore, it is required that each system of unitS be used independently of the other. Except for the diameter of bolts and flange bolt holes, combining values from the two systems constitutes nonconformance with the Standard.
2.2 References
Codes, standards, and specifications containing provisions to the extent referenced herein constitute requirements of this Standard. These references are listed in Mandatory Appendix II.
2.3 Quality Systems
Guidelines relating to the product manufacturer’s quality system programs are described in Nonmandatory Appendix A.
2.4 Service Conditions
Criteria for selection of material suitable for particular fluid service arc not rjthjn the scope of this Standard.
2.5 User Accountability
This Standard cites duties and responsibilities that are to be assumed by the flange or flange fitting user in the following areas:
(a) application
(b) installation
(c) system hydmstatic testing
(d) operation
(e) material selection
2.6 Time of Purchase, Manufacture, or Installation
The pressure—temperature ratings in this Standard arc applicable upon its publication to all flanges and flanged fittings within its scope that otherwise meet its requirements. For unused flanges or flanged fittings maintained in inventory, the manufacturer of the flanges or flanged fittings may certify conformance to this edition, provided that it can be demonstrated that all requirements oF this edition have been met, Where such components were installed in accordance with the pressure—temperature ratings of an earlier edition of this Standard, those pressure—temperature ratings are applicable except as may be governed by the applicable code or regulation.
2.7 DenotatIon
2.7.1 Pressure—Temperature Rating Designation. Class, foLlowed by a dimensionless number, is the designation for pressure—temperalure ratings as follows; Class 150, Class 300, Class 600, Class 900, Class 1500, and Class 2500.ASME B16.24 pdf download.
