ASME B16.11:2016 pdf download.Forged Fittings, Socket-Welding and Threaded.
ASME B16.11 covers ratings, dimensions, tolerances, marking, and material requirements for forged fittings, both socket-welding and threaded, as illustrated in Tables 1 through 6 and Tables 1-1 through 1-6, inclusive.
1.1.1 Fitting Types/Configuration. Types of fittings covered by this Standard are shown in Table 7, by class and size range. Fittings shown in Tables I through 6 and Tables I-I through 1-6 may also be made with combinations of socket-welding and threaded ends.
1.1.2 Special Fittings. Fittings with special dimensions, threads, or counterbores may be made by agreement between the manufacturer and purchaser. When such fittings meet all other stipulations of this Standard, they shall be considered in compliance therewith, provided they are appropriately marked (see section
4).
1.1.3 Welding. Installation welding requirements are not within the scope of this Standard. installation welding shall be in accordance with the applicable piping Code or regulation covering the piping system into which the fittings are installed.
1.2 General
1.2.1 Referenced Standards. Standards and specifica• tions adopted by reference in this Standard are shown in Mandatory Appendix Ii. It is not considered practical to identify the specific edition of each standard and specification in the individual references. Instead, the specific edition reference is identified in Mandatory Appendix ii. A fitting made in conformance and conforming to this Standard, in all other respects, will be considered to be in conformance to the Standard, even though the edition reference may be changed in a subsequent revision of the Standard.
1.2.2 Codes and Regulations. A fitting used under th( 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, rule governing the use of a material at low temperature, or provisions for operation at a pressure exceeding the ratings in this Standard.
1.2.3 Service Conditions. Criteria for selection of fitting types and materials suitable for particular fluid service are not within the scope of this Standard.
1.2.4 Quality Systems. Nonmandatory requirements relating to the product manufacturer’s quality system program are described in Nonmandatory Appendix A.
1.2.5 Relevant Units. This Standard states values in both SI (Metric) and U.S. Customary units. 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. Combining values from the two systems constitutes nonconformance with the Standard.
Tables 1 through 6 show fittings dimensional requirements in millimeters. Tables 1-1 through 1-6 show the dimensional requirements for inch dimensioned fittings.ASME B16.11 pdf download.
