The range of fittings and the range of sizes covered have been chosen to meet existing demands. In view of the wide diversity o
11、f use of these fittings, the user should satisfy himself that they are suitable for the conditions intended. The complementary standard for steel butt-welding fittings for the petroleum industry is BS 1640. Part 2 of this standard which dealt with austenitic stainless steel butt-welding fittings has
12、 been withdrawn. NOTE 1The figures in British units are regarded as standard. Metric conversions of the outside diameters and thicknesses of pipes and of the dimensions and tolerances of elbows and return bends given in Appendix B. Table 11 and Table 12 are ISO agreed corresponding values: other met
13、ric conversions are given in Appendix B. Table 13 are approximate and more accurate conversions of these should be based on Tables in BS 350, “Conversion factors and tables”. 1) BS 3601. “Steel pipes and tubes for pressure purposes: carbon steel with specified room temperature properties”. 2) BS 360
14、2. “Specification for steel pipes and tubes for pressure purposes: carbon and carbon manganese steels with specified elevated temperature properties”. -,-,- BS 1965-1:1963 BSI 03-1999iii NOTE 2In place of the customary, but incorrect, use of the pound and kilogramme as units of force, the units call
15、ed pound-force (abbreviation lbf) and kilogramme-force (abbreviation kgf) have been used in this standard. These are the forces which, when acting on a body of mass one pound or one kilogramme respectively, give it an acceleration equal to that of standard gravity. The unit called ton-force (abbrevi
16、ation tonf) has also been used where appropriate. 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 Standard does not of itself confer immunity from legal obli

This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover
18、. iv blank -,-,- BS 1965-1:1963 BSI 03-19991 1 Scope This British Standard applies to wrought carbon steel butt-welding pipe fittings for pressure purposes. It covers: 90 and 45 elbows; 180 return bends; concentric and eccentric reducers; equal tees; caps. Welding neck flanges are not included, but
19、they are provided for in BS 103). 2 Sizes Dimensions are standardized for the sizes and to the extent shown in Table 6 to Table 9. The size by which the fitting is designated shall be its nominal size except that for the 6 inch nominal size the outside diameter shall also be given. NOTEThe nominal s
20、ize corresponds to the nominal bore except for fittings of 14 in and 16 in sizes when the nominal size corresponds to the outside diameter. 3 Materials Unless otherwise agreed, fittings to this standard shall be made of materials complying with one of the undernoted standards: 4 Methods of manufactu
21、re Elbows, return bends and reducers shall be made from seamless or electric resistance welded pipe at manufacturers option unless otherwise agreed with the purchaser. Tees shall be made from seamless pipe or from forgings. Caps shall be made from plate. 5 Pressure ratings The maximum service pressu
22、re rating of a fitting to this standard shall be the same as that for a straight pipe of the same or equivalent material and the same nominal size and thickness. Where pressure/temperature conditions are important the relevant requirements of BS 8064) shall be observed. 6 Heat treatment Fittings on
23、which the final forming operation is completed at a temperature in the range 620 C (1 150 F) to 980 C (1 800 F) need not be heat treated provided they are cooled in still air. Fittings completed at temperatures below 620 C (1 150 F) shall be stress relieved at a temperature of from 580 C (1 075 F) t
24、o 620 C (1 150 F). 7 Dimensions of fittings Dimensions of fittings shall be in accordance with Table 6 to Table 10 subject to the provisions of Clause 8 and Table 2 to Table 5. The outside diameters and thicknesses of the welding ends of the fittings shall be as specified in Table 1. The body thickn
