12、2:1950 ii BSI 11-1999 Foreword This British Standard requires reference to the following standard: BS192, B.S.W. and B.S.F. open-ended carbon steel spanners. This British Standard supersedes BS670:1936, “Welded mild steel drums” and BS829:1939, “Mild steel drums for inflammable liquids,” and is the
13、first of a new series of British Standards for metal drums. BS670 was originally prepared at the joint request of the Association of British Chemical Manufacturers and the British Chemical Plant Manufacturers Association. It covered drums for liquids which do not flash below73 F.(22.7 C.) or develop
14、 a vapour pressure of more than20lb/sq. in. absolute below45 C.(113 F.) and included provisions for corrosive and heavy liquids. The preparation of BS829 was undertaken at the request of the same two organizations as well as the petroleum industry. The standard covered drums for most inflammable liq
15、uids not completely miscible with water and flashing below73 F. when tested in accordance with the requirements of the Petroleum (Consolidation) Act,1928, and represented an advance in the technique of transporting petroleum products of an inflammable nature. As a result of extensive tests carried o
16、ut by the railways and the oil companies it was found possible to standardize lighter drums than those previously in use. In arriving at the requirements for the constructional strength of the drum the conditions of transport normally associated with returnable packages were taken into consideration
17、. The present revision and amalgamation of these two standards has become necessary because of a demand from users that a wider range of drums should be specified, and that its details should be simplified. In view of the alternative methods of construction frequently used for drums having bodies th
18、inner than18B.G., such drums are omitted from the standard. It is pointed out that, although compliance with this British Standard will ensure satisfactory drums, the continuance of their serviceability will depend on systematic and periodic inspection and maintenance. A British Standard does not pu
19、rport 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 obligations. Summary of pages This document comprises a front cover, an inside front
20、 cover, pagesi andii, pages1 to8, an inside back cover and a back cover. 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.BS1702:1950 BSI 11-1999 1 1 Scope This British Standard cover
21、s heavy duty welded mild steel drums with fixed ends, with capacities from590imperial gal. It does not apply to the special drums required for the storage and conveyance of the following liquids: carbon disulphide 1)any liquid not complying with the pressure test described in the Appendix. The stand
22、ard also covers the44imperial gallon drum used by the petroleum industry. 2 Materials (body, ends, hoops and bands) a) Quality. The drums shall be made from thoroughly annealed good commercial quality low carbon mild steel sheets. End bands and rolling hoops shall be made of low carbon steel of good
23、 welding quality. b) Thickness. The thickness of the sheet metal used for the body and the end of the drums shall conform to the dimensions given in Table 1. The permissible variation in each gauge shall be as specified in BS1449 “Steel plate, sheet and strip”. 3 Construction and workmanship a) Body
24、. The body of the drums shall be made from a single sheet of metal. b) Ends. The ends, after being flanged to the appropriate depth, shall be a good fit in the body of the drum. c) Welding. All drums shall be welded by a suitable welding process. d) Rolling hoops and beads. Drums under20imperial gal
25、. in nominal capacity shall normally be supplied with a plain body, but if required by the purchaser two rolling hoops, not less than* in. deep, shall be pressed out from the body of the drum. Round the body of drums of20imperial gal. and over nominal capacity shall be fitted two1“ in. 1in. “I” sect
26、ion mild steel rolling hoops, weighing2lb/ft, or where agreed between manufacturer and customer there shall be pressed out from the body of the drum two rolling hoops not less than# in deep. The “I” section mild steel rolling hoops shall be shrunk on or, where required, secured by means of a small b
27、ead formed in the body of the drum on each side of the rolling hoop. NOTEThe latter method is not recommended for galvanized drums. e) Reinforcement. The circumferential junction of the body and ends shall be reinforced with mild steel bands of either lipped or convex feather edge section, as specif
28、ied in Clause4 (see Figure 1). f) Closures. The drums shall be fitted with screw bungs, flanges and washers as specified in Clause7. 4 Reinforcement The circumferential seam at each end of the drum shall be strengthened by either lipped or convex feather edge section bands, made from mild steel bars
29、 of the type and dimensions shown below: Drums under20 imperial gal. nominal capacity Drums20 imperial gal. nominal capacity and over When Type A construction is used the body and ends of the drum shall be welded together by a suitable process and the external lipped section band shrunk into positio
30、n. When Type B or C construction is used the body, ends and convex section bands shall be welded together. 1) The construction of drums for carbon disulphide is specified in Statutory Rules and Orders1935, No.283,1st Schedule.

32、ity, type and class shown in Table 1. 6 Dimensions, tolerances and ullage a) Dimensions. The drums shall conform to the dimensions given in Table 1, subject to the tolerances specified in Clause6 b). These dimensions provide for an ullage of not less than5percent (e.g.a50imperial gal. drum would hav
33、e a52“ imperial gal. water capacity). NOTEIf an intermediate capacity or larger ullage is required, the diameter shall be the standard diameter of the drum of the next higher, or lower, capacity, as appropriate. The length shall be such as to provide the required capacity in conjunction with this di
34、ameter. The gauge of metal for the body and ends shall be that given for the next larger standard size of drum of the appropriate class. b) Tolerances. The tolerances on internal diameter and external length shall be( in. 7 Closures Drums shall be provided with bungs and flanges made from good weldi
35、ng quality mild steel drop forgings. The heads of the bungs shall be hexagonal to allow of removal by means of a spanner, and shall have a recess to allow of removal by means of a key. The flange shall be continuously welded around its outer edge to the drum and shall not project into the interior.
36、The underside of the heads of the bungs and the top face of the flanges shall be machined surfaces and they shall be square to the threads. Sealing holes shall be provided in the bungs and in lugs on the flanges to permit the closure to be sealed by means of wire and metal seals. Figure 1 Reinforcem

40、e drum as above, or the large bung and flange may be fitted on the body of the drum between the rolling hoops, and the small bung and flange in one end near the chimb and diametrically opposed to the large bung and flange in the body of the drum. The closures shall be completed with washers made of
41、a material suitable for use with the liquid to be packed in the drum. The closures, when fitted in the end or when fitted in the body of the drum, shall not project above the chimb or rolling hoops.
