18、icesASME 831.5 92 O759670 O530264 LTB FOREWORD The need for a national code for pressure piping became increasingly evident from 1915 to 1925.To meet this need,the American Engineering Standards Committee(later changed to American Standards As-sociation,then changed to United States of America Stand
19、ards Institute,and now known as the American National Standards Institute)initiated project B31 in March 1926,at the request of the American Society of Mechanical Engineers and with that Society the sole administrative sponsor.Because of the wide field in-volved,Sectional Committee B31,later changed
20、 to Standards Committee,was composed of representa-tives of some 40 different engineering societies,indus-tries,government bureaus,institutes,and trade associa-tions.After several years work,the first edition was published in 1935 as an American Tentative Standard Code for Pressure Piping.In order t
21、o keep the Code abreast of current develop-ments in piping design,welding,stress computations,new dimensional and material standards and specifica-tions,and increases in the severity of service conditions,revisions,supplements,and new editions of the Code were published as follows:B3 1.1-1942 Americ

23、ion and Distribution Piping Sys-tems.In 1955,after a review by B31 Executive and Sectional Committees,a decision was made to develop and publish other industry sections as separate code documents of the American Standard Code for Pres-sure Piping.The first edition of Refrigeration Piping was pub-lis
24、hed as ASA B3 1.5-1962 superseding Section 5 of B31.1-1955.This Section was revised in 1966.Follow-ing approval by the Sectional Committee and the spon-sor,this revision was approved by the United States of America Standards Institute on September 8,1966,and designated USAS B31.5-1966.Revision of th
25、is Section was approved on April 18,1974,by the American Na-tional Standards Institute and designated ANSI B31.5-1974.In December 1978,the American National Stan-dards Committee B31 was reorganized as the ASME Code for Pressure Piping,B31,Committee under pro-cedures developed by the American Society
26、 of Mechan-ical Engineers and accredited by the American Na-tional Standards Institute.The Code designation was also changed to ANSVASME B31.The 1983 and 1987 Editions preceded this Issue.Addenda from 1989 have been included in this 1992 Edition.Refrigerant design pressures and refrigerant classific
