Copyright ASME International Provided by IHS under license with ASMENot for ResaleNo reproduction or networking permitted without license from IHS-,-FOREWORD In 192 1 the American Engineering Standards Committee, later the American St

11、andards Association (ASA), organized Sectional Committee B 16 to unify and further develop national standards for pipe flanges and fittings (and, later, for valves, gaskets, and valve actuators). Cosponsors of the B16 Committee were the American Society of Mechanical Engineers (ASME), the Heating an

12、d Piping Contractors National Association (now the Mechanical Contractors Association of America (MCAA), and the Manufacturers Standardization Society of the Valve and Fittings Industry (MSS). Cosponsors were later designated as cosecretariat organizations. Pioneer work on standardization of end-to-

13、end dimensions of valves began in 1917 under the direction of J. A. Stevens. It was put aside at the end of World War I and interest did not revive until 1926. ASA and ASME agreed to include the topic in the scope of the B 16 Committee, and Subcommittee 5 (now Subcommittee E) was established for the

14、 purpose. Work began in 1928 and covered ferrous flanged-end gate, globe, angle, and check valves. Development of a national standard was hindered by the diversity of existing practices and by adverse economic conditions in the early 1930s. A proposed 1933 American Standard for face-to-face dimensio

15、ns of ferrous flanged valves did not gain acceptance, even though it was largely based on a 1931 Standard Practice of MSS. Further work and industry developments led to a meeting in May 1937, which undertook to reconcile differences among the draft ASA standard, two American Petroleum Institute (API

16、) standards (5-Ci- 1 on pipeline valves and 600A on flanged OS however, they should not contain proprietary names or information. Requests that are not in this format will be rewritten in this format by the Committee prior to being answered, which may inadvertently change the intent of the original

17、request. ASME procedures provide for reconsideration of any interpretation when or if additional information that might affect an interpretation is available. Further, persons aggrieved by an interpretation may appeal to the cognizant ASME Committee or Subcommittee. ASME does not “approve,” “certify

18、,” “rate,” or “endorse” any item, construction, proprietary device, or activity. Attending Committee Meetings. The B 16 Main Committee regularly holds meetings, which are open to the public.

30、d dimensions of straightway valves, and center-to-face and center-to-end dimensions of angle valves. Its purpose is to assure installation interchangeability for valves of a given material, type, size, rating class, and end connec- tion. Face-to-face and center-to-face dimensions apply to flanged en

31、d valves with facings defined in para. 2.3.1 and to other valves intended for assembly between flat face or raised face flanges. End-to-end dimensions apply to grooved end, buttwelding end, and flanged end valves with facings defined in para. 2.3.3. Center- to-end dimensions apply to buttwelding end

32、 and to flanged end valves with facings defined in para. 2.3.3. In Tables 1 to 6 (Tables Al to A6), A or D in a column head denotes valves having flanged ends as illustrated; B or E denotes valves having buttwelding ends. 1.2 Standard Units Only flanged end valves (and others intended for assembly b

33、etween flanges) are covered by this Standard. Mating dimensions and facings of flanged ends conform to those in ASME B 16.1. Dimensional tables for various types and sizes of valves are as follows. 1.3.1 Gate, Plug, and Check Valves (a) Class2 125 - Tables 1 and Al (b) Class 250 - Tables 2 and A2 1.

34、3.2 Globe and Angle Valves (a) Class 125 - Tables 1 and Al (b) Class 250 - Tables 2 and A2 1.3.3 Wafer Swing Check Valves (a) Class 125 - Tables 7 and A7 (b) Class 250 - Tables 7 and A7 1.3.4 Butterfly Valves (a) Class 25 - Tables 8 and A8 (b) Class 125 - Tables 8 and A8 The values stated in either

35、millimeter units (Tables 1.4 Ductile Iron Valves 1 to 10) or inch units (Tables Al to AIO) are to be regarded separately as standard. Within the text, the inch units are shown in parentheses. The values stated in each system are not exact equivalents; therefore, each system must be used independentl

36、y of the other. Combining values from the two systems may result in nonconformance with the standard. Only flanged end valves (and others intended for assembly between flanges) are covered. Mating dimen- sions and facings of flanged ends conform to those in ASME B16.42. Valves are rated Class 150 an

37、d Class 300. The following cast iron and steel dimensional tables are also used for ductile valves. (a) Class 150 - Tables 1 and Al (b) Class 300 - Tables 2 and A2 Linear inch dimensions in this Standard are expressed using two- place decimal fractions. These values are actually common fractions of

38、an inch rounded to the nearest two-place decimal value as follows: 0.03 = 132 0.06 = /I6 0.12 = /H 0.19 = 3/16 0.22 = 7/32 0.31 = 116 0.38 = 3/s 0.44 = 116 0.50 = 12 0.56 = 9/i6 0.69 = /i6 0.75 = 314 0.94 = “/i6 0.16 = 132 0.62 = 5/H 0.25 = I/J 0.88 = 7/H 1.5 Steel and Alloy Valves This category inc

39、ludes carbon, alloy, and stainless steels, and the nonferrous materials listed in ASME B 16.34. It includes flanged, buttwelding, and grooved ends, as well as the types of valves intended for assembly between flanges. Mating dimensions and fac- ings of flanged ends conform to those in ASME B16.5, *

The valve size is not necessarily the same as the inside diameter or port diameter. 2.1.2 NPS (Nominal Pipe Size). The size of a connections. This is denoted by NPS, a d

46、Standard, the convention for fixing significant digits where limits, maximum or minimum values, are speci- fied shall be “rounding off“ as defined in ASTM Practice E29. This requires that an observed or calcu- lated value shall be rounded off to the nearest unit in the last right-hand digit used for

47、 expressing the limit. Decimal values and tolerance do not imply a particular method of measurement. 2 DEFINITIONS 2.1 Valve Size Designation 2.1.1 (DN) (Nominal Diameter). The size of a valve is designated by the nominal size of its end connections. This is denoted by (DN), a dimensionless number i

48、ndirectly related to the physical size of the 2.1.3 Reduced port, gate, and ball valves conforming to API 6D are designated for size by two numbers, the first being the NPS (DN) on the valve ends, the second being the NPS (DN) of the port (seats, moving parts, etc.); e.g., NPS 6 X 4 (DN 150 x 100) d

These valves shall have face-to-face or end-to-end dimensions corresponding to valves having the same size end connections; i.e., a NPS 6 x 4 (DN 150 x 100) valve shall have the face-to-face or end-to-end dimensions of a NPS 6 (DN 150) valve. 2.1.4 Reduced port, pressure seal bonnet, gate, globe, and check valves are designated fo
