Full Description

SCOPE

1.1 General This Standard Practice covers pressure-temperature ratings, materials, dimensions, tolerances (by references to ASME B16.5), marking and testing. The welding neck type flanges shall be forged steel, and the blind flanges may be made of either forged steel or from steel plates.

1.1.1 Dimensional requirements for sizes NPS 10 and smaller are provided by references to ASME B16.5. When such flanges meet all other stipulations of this standard, they shall be considered as complying therewith.

1.2 References
1.2.1 References Standards Standards and specifications adopted by reference in this Standard Practice are shown in Annex D, for convenience of identifying edition number, date and source of supply.

A flange made in conformance with a prior edition of referenced standards and in all other respects conforming to this Standard Practice will be considered to be in conformance even though the edition reference may be changed in a subsequent revision of this Standard Practice.

1.2.2 Codes and Regulations A flange used under the jurisdiction of the ASME Boiler and Pressure Vessel Code, the ANSI Code for Pressure Piping, or Governmental Regulations, is subject to any limitatino of that code or regulation. This includes any maximum temperature limitation for a material, or rule governing the use of a material at a low temperature.

1.3 Relevant Units This Standard Practice states values in both metric and U.S. Customary units. As an exception, diamete rof bolts and flange bolt holes are expressed in inch 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, combined tables, or in separate tables. 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 diameter of bolts and flange bolt holes, combining values from teh two systems constitutes nonconformance with the Standard Practice.
