FOREWORD (This Foreword is not part of ASME 616.45-1998) In the spring of 1920, the American Engineering Standards Committee (later successively named American Standards Association, United States of America Standards Institute, and American National Standards Institu
11、te) authorized the organization of a Sectional Committee (later named Standards Committee) on the Standardization of Pipe Flanges for the purpose of unifying and further developing the flanged and threaded fitting standards in force in the United States. Designated as joint sponsors were the America
12、n Society of Mechanical Engineers, the Heating and Piping Contractors National Association (later the Mechanical Contractors Association of America), and the Manufacturers Standardization Society of the Valve and Fittings Industry. In 1982, American National Standards Committee B16 was reorganized a
13、s the ASME B16 Committee, with ASME operating as sole sponsor under procedures accredited by ANSI. The Sovent system for plumbing drainage systems was developed in Switzerland, in 1961, by Mr. Fritz Sommer. Patent rights for the United States, where the system is finding use in high rise development
14、s, were obtained in late 1969. The Manufacturers Standardization Society of the Valve and Fittings Industry developed and approved SP-74 in September 1970. A few months later, the MSS publication was submitted to Standards Committee B16, whose Subcommittee 9 (now Subcommittee J) gave prompt approval
15、 to the proposal. After Standards Committee approval, some delay was encountered in providing necessary assurances to ANSI, but approval was finally granted to ANSI B16.32-1973, Cast Copper Alloy Solder Joint Fittings for Sovent Drainage Systems. Approval was subsequently received for ANSI B16.43-19
16、82, Wrought Copper and Copper Alloy Solder Joint Fittings for Sovent Drainage Systems. In 1982, Subcommittee B was requested to develop a standard for cast iron material. Following approval by the B16 Main Committee and the ASME Supervisory Board, approval was granted by ANSI for ASME/ANSI B16.45, C
17、ast Iron Fittings for Sovent Drainage Systems, on May 13, 1987. In the 1998 edition of ASME B16.45, reference standards are updated, a quality system program annex is added, and several editorial revisions are made. Following approval by ASME B16 Subcommittee B and B16 Main Committee, ANSI approved
18、this American National Standard on November 20, 1998. All requests for interpretations or suggestions for revisions should be sent to the Administra- tive Secretary, B16 Committee, American Society of Mechanical Engineers, Three Park Avenue, New York, NY 10016-5990. 111 ASME B16 COMMITTEE Standardiz

27、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 Main Committee The American Society of Mechanica
28、l Engineers Three Park Avenue New York, NY 10016-5990 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 pe
29、riodically. 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. Upo
30、n 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 Main Committee. The request for interpretation should be clear and unambiguous. It is further recommen
31、ded 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
32、 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, which are necessary to explain the question; however, they should not contain proprietary
33、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
34、 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 Meeting
35、s. The B16 Main Committee regularly holds meetings, which are open to the public. Persons wishing to attend any meeting should contact the Secretary of the B16 Main Committee. vii CONTENTS Foreword Standards Committee Roster .

43、Code - 1996 (d) Connections shall conform to sizes and dimen- sions listed in Table 1 or 2. Joint connections are designed for use with hubless soil pipe couplings con- forming to the requirements of the Cast Iron Soil Pipe Institute Specification 3 10-85. 3 SIZES3 (a) Sizes and dimensions of fittin
44、gs shall conform to dimensions in Table 1 or 2. (b) Opening size sequence is illustrated in Figs. 3 and 4. 4 MARKING (a) Each fitting shall be marked with the manufactur- ers name or trademark, and with “Sovent.” (b) Fittings of gray cast iron do not require material marking. If the manufacturer ele
45、cts to use malleable iron or ductile iron, the fitting shall be marked with “MI” or “DI.” 5 MATERIAL (a) The material used to manufacture the fittings shall be in accordance with ASTM A 126, Grade A. (b) At the option of the manufacturer, fittings may be furnished of malleable iron complying with th
46、e requirements of ASTM A 197 or A 47, Grade 32510, or of ductile iron complying with ASTM A 395 or A 536, Grade 65-45-12. 6 PITCH All nominal 90 deg drain openings shall be pitched down toward the fitting in a slope of /4 in./ft (2.1%) of horizontal pipe with reference to a horizontal plane. 3 The u
47、se 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 only.
