30、or a national code for pressure piping became increasingly evident from 1915 to1925. To meet this need, the American Engineering Standards Committee (later changed to theAmerican Standards Association ASA) initiated Project B31 in March 1926 at the request of TheAmerican Society of Mechanical Engine

31、ers (ASME), and with that society as sole sponsor. Afterseveral years work by Sectional Committee B31 and its subcommittees, a first edition waspublished in 1935 as an American Tentative Standard Code for Pressure Piping.A revision of the original tentative standard was begun in 1937. Several more y

32、ears effort wasgiven to securing uniformity between sections and to eliminating divergent requirements anddiscrepancies, 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 thisperio

33、d, a new section was added on refrigeration piping, prepared in cooperation with TheAmerican Society of Refrigeration Engineers (ASRE) and complementing the American StandardCode for Mechanical Refrigeration. This work culminated in the 1942 American Standard Codefor Pressure Piping.Supplements 1 an

34、d 2 of the 1942 code, which appeared in 1944 and 1947, respectively, introducednew dimensional and material standards, a new formula for pipe wall thickness, and morecomprehensive requirements for instrument and control piping. Shortly after the 1942 code wasissued, procedures were established for h

35、andling inquiries that require explanation or interpreta-tion of code requirements, and for publishing such inquiries and answers in MechanicalEngineeringfor the information of all concerned.Continuing increases in the severity of service conditions, with concurrent developments ofnew materials and

36、designs equal to meeting these higher requirements, had pointed to the needby 1948 for more extensive changes in the code than could be provided by supplements alone.The decision was reached by ASA and the sponsor to reorganize the Sectional Committee andits several subcommittees, and to invite the

37、various interested bodies to reaffirm their representa-tives or to designate new ones. Following its reorganization, Sectional Committee B31 made anintensive review of the 1942 code, and a revised code was approved and published in February 1951with the designation ASA B31.1-1951, which included(a)

38、a general revision and extension of requirements to agree with practices current at the time(b) revision of references to existing dimensional standards and material specifications, andthe addition of references to new ones(c) clarification of ambiguous or conflicting requirementsSupplement No. 1 to

39、 B31.1 was approved and published in 1953 as ASA B31.1a-1953. ThisSupplement and other approved revisions were included in a new edition of B31.1 published in1955 with the designation ASA B31.1-1955.A review by B31 Executive and Sectional Committees in 1955 resulted in a decision to developand publi

40、sh industry sections as separate code documents of the American Standard B31 Codefor Pressure Piping. ASA B31.4-1959 was the first separate code document for Oil TransportationPiping Systems and superseded that part of Section 3 of the B31.1-1955 code covering oiltransportation piping systems. In 19

41、66, B31.4 was revised to expand coverage on welding, inspec-tion, and testing, and to add new chapters covering construction requirements and operationand maintenance procedures affecting the safety of the piping systems. This revision was publishedwith the designation USAS B31.4-1966, Liquid Petrol

42、eum Transportation Piping Systems, sinceASA was reconstituted as the United States of America Standards Institute (USASI) in 1966.USASI changed its name, effective October 6, 1969, to the American National Standards Institute,Inc. (ANSI), and USAS B31.4-1966 was redesignated as ANSI B31.4-1966. The

43、B31 SectionalCommittee was redesignated as American National Standards Committee B31 Code for PressurePiping, and, because of the wide field involved, more than 40 different engineering societies,vigovernment bureaus, trade associations, institutes, and the like had one or more representativeson Sta

44、ndards Committee B31, plus a few Individual Members to represent general interests.Code activities were subdivided according to the scope of the several sections, and generaldirection of Code activities rested with Standards Committee B31 officers and an ExecutiveCommittee whose membership consisted

45、 principally of Standards Committee officers andchairmen of the Section and Technical Specialists Committees.The ANSI B31.4-1966 Code was revised and published in 1971 with the designationANSI B31.4-1971.The ANSI B31.4-1971 Code was revised and published in 1974 with the designationANSI B31.4-1974.I

46、n December 1978, American National Standards Committee B31 was converted to anASME Committee with procedures accredited by ANSI. The 1979 revision was approved by ASMEand subsequently by ANSI on November 1, 1979, with the designation ANSI/ASME B31.4-1979.Following publication of the 1979 Edition, th

47、e B31.4 Section Committee began work onexpanding the scope of the Code to cover requirements for the transportation of liquid alcohols.References to existing dimensional standards and material specifications were revised, and newreferences were added. Other clarifying and editorial revisions were ma

48、de in order to improvethe text. These revisions led to the publication of two addenda to B31.4. Addenda b to B31.4was approved and published in 1981 as ANSI/ASME B31.4b-1981. Addenda c to B31.4 wasapproved and published in 1986 as ANSI/ASME B31.4c-1986.The 1986 Edition of B31.4 was an inclusion of t

49、he two previously published addenda into the1979 Edition.Following publication of the 1986 Edition, clarifying and editorial revisions were made toimprove the text. Additionally, references to existing standards and material specifications wererevised, and new references were added. These revisions led to the publication of an addendato B31.4 that was approved and published in 1987 as ASME/ANSI B31.4a-1987.The 1989 Edition of B31.4 was an inclusion of the previously published addenda into the 1986Edition.Following publication of the 1989 Edition, clarifying revi
