asme B16.48 2010 ed. Line Blanks

SCOPE This Standard covers pressure–temperature ratings, materials, dimensions, tolerances, marking, and testing for operating line blanks in sizes NPS 1⁄2 through NPS 24 for installation between ASME B16.5 flanges in the 150, 300, 600, 900, 1500, and 2500 pressure classes. 2 GENERAL 2.1 Definitions 2.1.1 Figure8 Blank. A figure8 blank (also called a spectacle blank) is a pressureretaining plate with one solid end and one open end connected with a web or tie bar (see Fig. 1). 2.1.2 Paddle Blank. A paddle blank is similar to the solid end of a figure8 blank. It has a plain radial handle. It is generally used in conjunction with a paddle spacer in large sizes. 2.1.3 Paddle Spacer. A paddle spacer is similar to the open end of a figure8 blank. It has a plain radial handle. It is generally used in conjunction with a paddle blank

July 1993, the ASME B16 Committee gave to its Subcommittee C the assignment to convert the API 590 Steel Line Blanks Standard into an ASME standard The American Petroleum Institute no longer publishes the API 590 Standard These line blanks were designed in accordance with the rules of the ASME B31.3-2002 edition Materials and relevant footnotes have been added following the ASME format Significant additions were made to the 2005 edition that included reference to the use of all materials listed in B16.5 Table 1-A plus Metric units The added materials of construction included additions to classes of alloy steels, stainless steels, and nickel alloys The 2005 edition was also metricated over previous editions to include both U.S Customary units (in parenthesis) and Metric units in the text, Metric units in dimensional tables in the body, and U.S Customary units in dimensional tables in Nonmandatory Appendix A Following the approval of the Standards Committee and ASME, approval for the 2005 edition was granted by the American National Standards Institute on September 19, 2005 The 2010 edition includes revisions to paragraph numbering and adjustments of appendices In addition to renumbering of main text, updates have been made to the Materials section and Marking Method Illustrations for the figure-8 blanks for raised face flange joints have been revised Finally, the tables for male ring-joint facing figure-8 blanks were revised to support both oval and octagonal ring shapes All requests for interpretations or suggestions for revisions should be sent to the Secretary, B16 Committee, The American Society of Mechanical Engineers, Three Park Avenue, New York, NY 10016-5990 The B16 Committee operates under procedures accredited by the American National Standards Institute (ANSI) Following approval by the Standards Committee and ASME, this revision to the 2005 edition was approved as an American National Standard by ANSI on September 2, 2010 with the designation ASME B16.48-2010 iv ASME B16 COMMITTEE Standardization of Valves, Flanges, Fittings, and Gaskets (The following is the roster of the Committee at the time of approval of this Standard.)

are developed and maintained with the intent to represent the consensus of concerned interests As such, users of this Standard may interact with the Committee by requesting interpretations, proposing revisions, and attending Committee meetings Correspondence should be addressed to: Secretary, B16 Standards Committee The American Society of Mechanical Engineers Three Park Avenue New York, NY 10016-5990 As an alternative, inquiries may be submitted via e-mail to SecretaryB16@asme.org Proposing Revisions Revisions are made periodically to the Standard to incorporate changes that appear necessary or desirable, as demonstrated by the experience gained from the application of the Standard Approved revisions will be published periodically The Committee welcomes proposals for revisions to this Standard Such proposals should be as specific as possible, citing the paragraph number(s), the proposed wording, and a detailed description of the reasons for the proposal, including any pertinent documentation Interpretations Upon request, the B16 Committee will render an interpretation of any requirement of the Standard Interpretations can only be rendered in response to a written request sent to the Secretary of the B16 Standards Committee The request for interpretation should be clear and unambiguous It is further recommended that the inquirer submit his/her request in the following format: Subject: Edition: Question: Cite the applicable paragraph number(s) and the topic of the inquiry Cite the applicable edition of the Standard for which the interpretation is being requested Phrase the question as a request for an interpretation of a specific requirement suitable for general understanding and use, not as a request for an approval of a proprietary design or situation The inquirer may also include any plans or drawings that are necessary to explain the question; however, they should not contain proprietary names or information Requests that are not in this format will be rewritten in this format by the Committee prior to being answered, which may inadvertently change the intent of the original request ASME procedures provide for reconsideration of any interpretation when or if additional information that might affect an interpretation is available Further, persons aggrieved by an interpretation may appeal to the cognizant ASME Committee or Subcommittee ASME does not “approve,” “certify,” “rate,” or “endorse” any item, construction, proprietary device, or activity Attending Committee Meetings The B16 Standards Committee regularly holds meetings, which are open to the public Persons wishing to attend any meeting should contact the Secretary of the B16 Standards Committee vi ASME B16.48-2010 SUMMARY OF CHANGES Following approval by
