There will be no addenda issued to this edition. ASME issues written replies to inquiries concerning interpretations of technical aspects of this Standard. Interpretations are published on the ASME Web site under the Committee Pages at http// www.asrne.org/codes/ as they are issued. Periodically certain actions of the ASME 831 Committee will be published as Cases.

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 several 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 uniity between sections 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, 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 1947 respectively, introduced new dimensional and material standards, a new ula 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 inter- pretation of Code requirements, and for publishing such inquiries and answers in Mechanical Engineering for the ination of all concerned. Continuing increases in the severity of service condi- tions, with concurrent developments of new materials and designs equal to meeting higher requirements, 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 interested 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 general 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 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 cutive and Sectional Committees in 1955 resulted in a decision to develop and publish 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 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 National 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 trans
