10、 piping, designated categorically as stainless, is based onthe same principles that formed the background for the development of ASME B36.10M, Weldedand Seamless Wrought Steel Pipe, and reference is made to this source of information.The more recent development of the highly alloyed stainless steels
11、 has brought about a minorconflict with convention. With these newer materials, the need for standards is just as great andthe present types of threads are just as satisfactory, but the basic cost of the metal is much higherand the art of fusion welding has developed concurrently. The character of s
12、tainless steel permitsthe design of thin-wall piping systems without fear of early failure due to corrosion, and the useof fusion welding to join such piping has eliminated the necessity of threading it. For thesereasons, the wall thickness dimensions shown under Schedule 10S have been developed, ba
13、sedon the conventional formula, but then modified to correspond to the nearest Birmingham WireGage (B.W.G.) number.Following publication of the 1949 edition, a demand developed for a still lighter wall pipe. ASchedule 5S was determined cooperatively by representatives of chemical companies, processi
14、ngindustries, and manufacturers of welding fittings. This was endorsed by the American StandardsAssociation (ASA) Chemical Industry Correlating Committee and the Manufacturers Standardiza-tion Society of the Valve and Fittings Industry. The new schedule was included in the revisedstandard that was a
15、pproved by ASA (now ANSI) on April 7, 1952.In 1956, it was recommended that the wall thickness of 12 in. 5S be lessened, and a new revisionof the standard was issued shortly after its approval by ASA on February 27, 1957. In this fourthedition, dimensions were expanded beyond 12 in. pipe size by inc
16、lusion of, and reference to,ASTM Specification A 409. This revision was approved by ASA on October 29, 1965.The B36 Standards Committee membership was asked in March 1970 for recommendations asto what action should be taken on ANSI B36.19-1965 since, according to ANSI procedures, thisstandard was du
17、e for revision or affirmation. The B36 Standards Committee recommendedreaffirmation. This action was approved by the Secretariat and by the American National StandardsInstitute on May 26, 1971.In 1975, the B36 Standards Committee undertook a review of the standard, considering itsacceptability and u
18、sefulness. The results were favorable; some editorial refinements and updatingwere proposed, along with the incorporation of factors for conversion to SI (metric) units. Therevision was approved by the Standards Committee, the Secretariat, and subsequently the Ameri-can National Standards Institute
19、on October 4, 1976.The standard was revised in 1984 to include SI (metric) dimensions. The outside diametersand wall thicknesses were converted to millimeters by multiplying the inch dimensions by 25.4.Outside diameters larger than 16 in. were rounded to the nearest 1 mm, and outside diameters16 in.
20、 and smaller were rounded to the nearest 0.1 mm. Wall thicknesses were rounded to thenearest 0.01 mm. These converted and rounded SI dimensions were added in Table 2A. A formulato calculate the SI plain end mass, kg/m, using SI diameters and thicknesses, was added to para.5. The SI plain end mass wa
21、s calculated for each size and thickness, and added in Table 3A.These changes in the standard were approved by the Standards Committee, the Sponsor, andANSI, and it was designated an American National Standard on October 7, 1985.The current edition revises the text to conform to the format and conte
22、nt, as appropriate, ofASME B36.10M-2004. Tables 2, 2A, 3, and 3A are replaced with a new Table 1, combining theinformation in the previous tables into a single table. Also, the roster of the disbanded B36Committee is replaced by the roster of the B32 Committee. This edition was approved as anAmerica
