BS1211, Centrifugally cast (spun) iron pressure pipes for water, gas and sewage. BS1560, Steel pipe flang
16、es and flanged fittings (nominal sizes“ in to24in) for the petroleum industry. BS1575, Cast iron pipe flanges and flanged fittings, Class125, for the petroleum industry. BS1576, Cast iron pipe flanges and flanged fittings, Class250, for the petroleum industry. BS1770, Pipe flanges for use on interna
17、l combustion engines and installations. BS2035, Cast iron flanged pipes and flanged fittings. BS3293, Carbon steel pipe flanges (over24in nominal size) for the petroleum industry. BS3381, Metallic spiral wound gaskets for the petroleum and petrochemical industry. This revised British Standard has be
18、en prepared under the authority of the Mechanical Engineering Industry Standards Committee, consequent upon the issue of BS10:1962 1) . It should be noted that wherever BS10 is referred to in this standard, the1962 edition is intended. The committee have given further thoughts to the various duties
19、of gaskets and have concluded, as before, that it is not practicable at present to specify materials and thicknesses. The plan dimensions of gaskets to suit flanges to BS10 and BS2035 2)have been revised. As regards flanges to BS2035, these are at present being brought into line with BS10:1962 by Co
20、mmittee ISE/16. The plan dimensions of gaskets to suit flanges to BS1770 3)remain unaltered. The outside dimensions of full face gaskets are the same as the outside dimensions of the flanges. The outside diameters of “inside bolt circle” gaskets to suit BS10 flanges are now equal to the bolt pitch c
21、ircle diameter less one bolt holediameter, to agree with BS10, Clause1. The inside diameters of gaskets to suit BS10 flanges are now equal to the outside diameters of the steel pipe appropriate to the flange size designation, except for gaskets to suit flanges to BS10, Table K (over6in nominal bore)
22、 and Table R and Table S; these dimensions are also suitable for centrifugally cast (“spun”) cast iron pipes made in accordance with BS1211 4)with screwed-on flanges. The inside diameters of gaskets to suit BS1770 flanges are equal to the maximum bores of the flanges. Full face gaskets are not speci
23、fied for BS10 flanges to Table R and Table S, and inside bolt circle gaskets for these flanges have been limited to sizes up to and including5in and3in flange size designations respectively. Dimensions for Table K gaskets have been limited to sizes up to and including15in flange size designation. Th
24、is is because above these sizes the thickness of steel pipe varies to such a wide extent as to make standardization impracticable. For the same reason, no gasket dimensions have been standardized for BS10, Table T. The tables in this British Standard have been lettered or numbered to conform to the
25、corresponding tables in the appropriate flange standards. 1) BS10:1962,“Flanges and bolting for pipes, valves and fittings”. 2) BS2035, “Cast iron flanged pipes and flanged fittings”. 3) BS1770, “Pipe flanges for use on internal combustion engines and installations”. 4) BS1211, “Centrifugally cast (
26、spun) iron pressure pipes for water, gas and sewage”.BS3063:1965 BSI 11-1999 iii NOTE 1When metric equivalents of the pipe dimensions in this standard are required reference should be made to the corresponding values in ISO Recommendations R64 5)and R65 6)as appropriate. When it is required to conve
27、rt the figures in this standard from British units into metric units it is recommended that the conversion factors and the table of conversions contained in BS350, “Conversion factors and tables”, be used. Attention is also drawn to BS2856, “Precise conversion of inch and metric sizes or engineering
28、 drawings”. NOTE 2Attention is drawn to the Appendix which gives a conversion table for inch to metric units. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British
29、 Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pagesi to iv, pages1to26 and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be in
30、dicated in the amendment table on the inside front cover. 5) ISO R64, “Steel tubes: outside diameters”. 6) ISO R65, “Steel tubes suitable for screwing in accordance with ISO Recommendation R7”.iv blankBS3063:1965 BSI 11-1999 1 Obsolescent (by Amendment No.1). This British Standard has been declared
31、obsolescent and is not recommended for use in new equipment but needs to be retained to provide for the servicing of existing equipment that is expected to have a long working life. 1 Scope This British Standard specifies the “plan” dimensions of gaskets suitable for use with flanges to BS10 7) , BS
32、1770 8)and BS2035 9) . This standard does not include spiral edge-wound or other special types of gasket. Dimensions of gaskets for use with flanges to BS10, Table K, Table R and Table S have been limited to sizes up to and including15in,5in and3in flange size designations respectively and no gasket
33、 dimensions have been standardized for BS10, Table T. This is because wide variations may occur in the actual inside diameters of steel pipes fitted with flanges of the same size designations to the higher tables of BS10. In such cases, it is not practicable to specify the inside diameter of gaskets
34、 and there would be little advantage in specifying the outside diameters only. NOTEGasket dimensions for flanges for the petroleum industry are given in the British Standards for pipe flanges and gaskets for the petroleum industry, BS1560 10) , BS3293 11) , BS3381 12) , BS1575 13)and BS1576 14) . 2
35、Definition For the purposes of this standard, the following definition applies: gasket packing which is used between flat flanges and faces 3 Dimensions The “plan” dimensions of gaskets to suit flanges to BS10 7)shall conform to those given in Table A to Table S. For pipes lined with bitumen or othe
36、r material, the inside diameter of gaskets may be altered by agreement between purchaser and manufacturer. The “plan” dimensions of gaskets to suit flanges to BS1770 8)shall conform to those given in Table 1 to Table 3. 4 Marking By agreement between purchaser and manufacturer gaskets which conform
37、to the dimensions specified in this standard may be marked with the BS number, table reference and flange size designation or flange reference number to which they refer. 7) BS10, “Flanges and bolting for pipes, valves and fittings”. 8) BS1770, “Pipe flanges for use on internal combustion engines an
