Description / Abstract:

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 7 and I1 through I4, inclusive.

Fitting Types/Configuration. Types of fittings covered by this Standard are shown in Tables 1A and 1B, by class and size range. Fittings shown in Tables 4 through 7 and I1 through I4 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 the purchaser. When such fittings meet all other stipulations of this Standard, they shall be considered in compliance therewith, 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.

References

Referenced Standards. Standards and specifications adopted by reference in this Standard are shown in Mandatory Appendix II, which is part of this Standard. 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 addendum to or revision of the Standard.

Codes and Regulations. A 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 operation at a pressure exceeding the ratings in this Standard.

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 units 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 7 show fittings dimensional requirements in millimeters. Tables I1 through I4 show the dimensional requirements for inch dimensioned fittings.
