ASME B16.11-2001 pdf free download.ASME B16 COMMITTEE Standardization of Valves, Flanges, Fittings, Gaskets, and Valve Actuators.
This Standard covers ratings, dimensions, tolerances, marking and material requirements for forged fitings, both socke-welding and threaded, as ilustrated in Tables 4 through 7 and II through 1I4, inclusive. 1.1.1 Fitting Types/Configuration. Types of fit- tings covered by this Standard are shown in Tables 1A and IB, by class and size range. Fltings shown in Tables 4 through 7 and Il through 1I4 may also be made with combinations of socket-welding and threaded ends. 1.1.2 Special Fittings. Fitings with special dimen- sions, threads or counterbores may be made by agreement between the manufacturer and the purchaser. When such fttings meet all other stipulations of this Standard, they shall be considered in compliance therewith, provided they are appropriatly marked (see para. 4). 1.1.3 Quality Systems. Nonmandatory require- ments relating to the product manufacturer’s Quality System Program are described in Nonmandatory Appen- dix A. 1.2 References 1.2.1 Referenced Standards. Standards and spec- ifications adopted by reference in this Standard are shown in Mandatory Appendix II, which is part of this Standard. It is not considered practical to identify the specific edition of each standard and specification in the individual references. Instead, the specific edition reference is identified in Mandatory Appendix II. A ftting made in conformance and conforming to this Standard, in all other respects, will be considered to be in conformance to the Standard, even though the edition reference may be changed in a subsequent addendum 10 or revision of the Standard. 1.2.2 Codes and Regulations. A flting used under the jurisdiction of the ASME Boiler and Pressure Vessel Code, the ASME Code for Pressure Piping, or a governmental regulation is subject to any limitation of that code or regulation. This includes any maximum temperature limitation, or rule governing the use of a material at low temperature, or provisions for operation at a pressure exceeding the ratings in this Standard. 1.3 Service Conditions Criteria for selection of ftting types and materials suitable for particular fluid service are not within the scope of this Standard. 1.4 Welding Installation welding requirements are not within the scope of this Standard. Installation welding shall be done in accordance with the applicable piping Code or regulation covering the piping system into which the fttings are installed. 1.5 Standard Units The values stated in either metric units or inch units are to be regarded separatly 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 independently of the other. Combining values from the two systems may result in nonconformance with the standard. Tables 4 through 7 show ftings dimensional require- ments in millineters. Tables II through 14 show the dimensional requirements for inch dimensioned fitings. 2 PRESSURE RATINGS 2.1 General These fttings shall be designated as Class 2000, 3000，and 6000 for threaded end fttings and Class 3000, 6000, and 9000 for socket-weld end fttings. 2.1.1 Basis of Rating. The schedule of pipe corres- ponding to each Class of ftting for ating purposes is shown in Table 2. Design temperature and other service conditions shall be limited as provided by the applicable piping code or regulation for the material of construction of the ftting. Within these limits the maximum allow- able pressure of a ftting shall be that computed for straight seamless pipe of equivalent material (as shown by comparison of composition and mechanical proper- ties in the respective material specifications). The wall thickness used in such computation shall be that tabu- lated in ASME B36.10M for the size and applicable schedule of pipe reduced by applicable manufacturing tolerances and other allowances (e.g.. threaded allow- ances). Any corrosion allowance and any variation in allow- able stress due to temperature or other design shall be applied to the pipe and ftting alike.ASME B16.11 pdf download.
