Title
Forged Fittings, Socket-Welding and Threaded
ASME International
Publication Date:
Dec 5, 2005
Scope:
General
This Standard covers ratings, dimensions, tolerances, marking, and material requirements for forged fittings, both socket-welding and threaded, as illustrated in Tables 4 through 8 and Tables I-1 through I-5, inclusive.
Fitting Types/Configuration.
Types of fittings covered by this Standard are shown in Table 1, by class and size range. Fittings shown in Tables 4 through 8 and Tables I-1 through I-5 may also be made with combinations of socket-welding and threaded ends.
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 there-with, provided they are appropriately marked (see para. 4).
Quality Systems.
Nonmandatory requirements relating to the product manufacturer’s Quality System Program are described in Nonmandatory Appendix A.
Service Conditions
Criteria for selection of fitting types and materials suitable for particular fluid service are not within the scope of this Standard.
Welding
Installation welding requirements are not within the scope of this Standard. Installation welding shall be done in accordance with the applicable piping Code or regulation covering the piping system into which the fittings are installed.
Standard Units
The values stated in either metric or inch units are to be regarded separately as standard. Within the text, the inch units are shown in parentheses. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.
Tables 4 through 8 show fittings dimensional requirments in millimeters. Tables I-1 through I-5 show the dimensional requirements for inch dimensioned fittings.
