26、ngly evident from 1915 to 1925. To meet this need the American Engineering Standards Commit- tee (later changed to the American Standards Associa- tion) initiated Project B31 in March 1926 at the request of the American Society of Mechanical Engineers, and with that society as sole sponsor. After se

27、veral years work by Sectional Committee B31 and its subcommit- tees, a first edition was published in 1935 as an American Tentative Standard Code for Pressure Piping. A revision of the original tentative Standard was begun in 1937. Several more years effort was given to securing uniformity between s

28、ections and to eliminating divergent requirements and discrepancies, as well as to keeping the Code abreast of current developments in welding technique, stress computations, and references to new dimensional and material standards. During this period a new section was added on refrigeration piping,

29、 prepared in cooperation with the American Society of Refrigeration Engineers and complementing the Ameri- can Standard Code for Mechanical Refrigeration. This work culminated in the 1942 American Standard Code for Pressure Piping. Supplements 1 and 2 of the 1942 Code, which appeared in 1944 and 194

30、7 respectively, introduced new dimensional and material standards, a new formula for pipe wall thickness, and more comprehensive require- ments for instrument and control piping. Shortly after the 1942 Code was issued, procedures were established for handling inquiries that require explanation or in

31、ter- pretation of Code requirements, and for publishing such inquiries and answers in Mechanical Engineering for the information of all concerned. Continuing increases in the severity of service condi- tions, with concurrent developments of new materials and designs equal to meeting higher requireme

32、nts, had pointed to the need by 1948 for more extensive changes in the Code than could be provided by supplements alone. The decision was reached by the American Stan- dards Association and the sponsor to reorganize the sectional committee and its several subcommittees, and to invite the various int

33、erested bodies to reaffirm their representatives or to designate new ones. Following its reorganization, Sectional Committee B31 made an inten- sive review of the 1942 Code, and a revised Code was approved and published in February 1951 with the des- ignation ASA 831.1-1951, which included (a) a gen

34、eral revision and extension of requirements to agree with practices current at the time (b) revision of references to existing dimensional stan- dards and material specifications, and the addition of references to new ones (c) clarification of ambiguous or conflicting require- ments Supplement No. 1

35、 to 831.1 was approved and pub- lished in 1953 as ASA B31.la-1953. This supplement and other approved revisions were included in a new edition of B31.1 published in 1955 with the designation ASA A review by B31 Executive and Sectional Committees in 1955 resulted in a decision to develop and publish

36、industry sections as separate Code documents of the American Standard B31 Code for Pressure Piping. Shortly thereafter, separate Code documents were pre- pared for each of the then existing piping systems within the American Standard B31 Code for Pressure Piping., The American Standards Association

37、was reconstitu- ted as the United States of America Standards Institute in 1966, and as the American National Standards Insti- tute, Inc., in 1969. The B31 Sectional Committee was redesignated as American National Standards Commit- tee B31 Code for Pressure Piping. In December 1978, American Nationa

38、l Standards Committee B31 was reor- ganized as the ACME Code for Pressure Piping B31 Com- mittee, under procedures developed by the American Society of Mechanical Engineers and accredited by ANSI. By 1977 the technology of slurry pipeline transporta- tion had developed enough to permit the preparati

39、on of a Code, and in that year representatives of the slurry pipeline transportation industry asked the B31 Commit- tee to prepare such a Code. The B31 Committee agreed to the request and ANSI/ASME 831.11-1986, Slurry Transportation Piping Systems, was the result of that effort. After approval by th

40、e B31 Committee and ASME (the sponsor), that Code was approved by the American National Standards Institute on June 3, 1986. Following publication of the 1986 edition, the B31.11 Section Committee revised the references to existing dimensional standards and material specifications and added new refe

41、rences. Other clarifying and editorial revisions were made in order to improve the text. These revisions led to the publication of an addenda to B31.11. Addenda ”a” to B31.11 was approved and published in 1988 as ANSI/ASME B31.11a-1988. The 2002 Edition of B31.11 is an inclusion of the pre- viously

42、published addenda into the 1989 Edition along with numerous revisions to the text and updated refer- ences. This 2002 Edition was approved by the American National Standards Institute on August 5,2002 and des- ignated as ASME B31.11-2002. B31.1-1955. V Copyright ASME International Provided by IHS un
