Standard Details

Scope:
This Standard covers cast Classes 125 and 250 copper alloy threaded pipe fittings with provisions for substituting wrought copper alloys for plugs, bushings, caps, and couplings in small sizes. This Standard includes the following:

(a) pressure–temperature ratings

(b) size and method of designating openings of reducing pipe fittings

(c) marking requirements

(d) minimum requirements for casting quality and materials

(e) dimensions and tolerances in SI (metric) and U.S. Customary units

(f) threading requirements

(g) pressure test requirements

Mandatory Appendix I provides table values in U.S. Customary units.

Convention

For the purpose of determining conformance with this Standard, the convention for fixing significant digits where limits, maximum or minimum values, are specified shall be rounded as defined in ASTM E 29. This requires that an observed or calculated value shall be rounded off to the nearest unit in the last right-hand digit used for expressing the limit. Decimal values and tolerances do not imply a particular method of measurement.

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 the standard. Within the text the Customary units are shown in parentheses or in separate tables in Mandatory Appendix I. 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.

Quality Systems

Requirements relating to the product manufacturer's Quality System Programs are described in Nonmandatory Appendix A.

Denotation

Pressure Rating Designation.

Class, followed by a dimensionless number, is the designation for pressure–temperature ratings (e.g., Class 125 and Class 250).

Size.

NPS, followed by a dimensionless number, is the designation for nominal fittings size (e.g., NPS 2).

Time of Purchase, Manufacture, or Intallation

The pressure–temperature ratings in this Standard are applicable upon its publication to all fittings within its scope that otherwise meet its requirements. For unused fittings maintained in inventory, the manufacturer of the 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 ratings are applicable except as may be governed by the applicable code or regulation.

User Accountability

This Standard cites responsibilities that are to be assumed by the fitting user in the areas of the temperature at which the pressure rating is taken.

Service Conditions

Criteria for selection of materials suitable for particular fluid service are not within the scope of this Standard.

Description :

This Standard pertains primarily to cast Class 125 and Class 250 bronze threaded pipe fittings. Certain requirements also pertain to wrought or cast plugs, bushings, couplings, and caps. This Standard covers:

(a) pressure-temperature ratings;

(b) size(Footnote 1) and method of designating openings of reducing pipe fittings;

(c) marking;

(d) minimum requirements for casting quality and materials;

(e) dimensions(Footnote 1) and tolerances in U.S. customary and metric (SI) units;

(f) threading.

Footnote 1 - The use of the word nominal as a modifier of a dimension or size is intended to indicate that the stated dimension or size is used for purposes of designation. The actual dimension may be the nominal dimension subject to the variation of established tolerances.
