20、TION FOR - HOSE COUPLINGS FOR PETROL, OIL AND LUBRICANTS (% IN. TO 4 IN. NOMINAL SIZES) FOREWORD his British Standard has been prepared under the authority of the Mechanical Engineering Industry Standards Committee in response to a request from the Joint Services Committee. These couplings have been

21、 designed primarily for duties in connection with filling and discharging of rail and road cars and dispensing equipment. Two forms of screw threads have been specified for the couplings : Whitworth (B.S.P.) threads in accordance with B.S. 84*, and American threads in accordance with ASA specificati

22、on B33.1 (3/4 in. to 2 in.) and with Federal Standard Stock Catalogue ZZ-H466b (November, 1935) (234 in. to 4 in.) (see Appendices A and B). These latter threads have been specified to ensure that the couplings connect with oil equip- ment screwed in accordance with API.STD. 5L and 6A. Appendices A

23、and B have been included, giving the dimensions and tolerances of the American hose-coupling screw threads, but details of the pilot at the beginning of the male thread and the length of the nippie have been excluded. The couplings may be secured to the hose by clamps, by clips or by other suitable

24、means. It is essential that suitable hose be used in conjunction with the couplings covered by this standard. Such hose should be sufficiently thick and heavy to withstand the pressure required (see Clause 1, last paragraph) but it should be pliable enough to enable it to be compressed on to the cou

25、pling for attachment purposes. This standard forms one of a series for hose couplings, the other British Standards in this series being :- B.S. 336, Fire hose and suction hose couplings, branch pipes and B.S. 1782, Hose couplings (1% in. to 8 in. nominal sizes) other than B.S. 1906, Hose couplings (

26、air and water) (% in. to 1% in. nominal AS N added 1962 nozzle connections. fire hose couplings. sizes). SPECIFICATION 1. This British Standard applies to the following types of reduced bore couplings and adaptors:- SCOPE * B.S. 84, Screw threads of Whitworth form . . B.S. 2464 : 1954 a. Couplings w
