Price based on 2 pages Copyright International Organization for Standardization Not for Resale FOREWORD IsO (the International Organization for Standardization) is a worldwide federation of national standards institutes (isO member bodies). The work of developing International Standards is carried out through ISO technical committees. Every member body interested in a subject for which a technical committee has been set up has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with IsO, also take part in the work. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as Internationa! Standards by the ISO Council. International Standard ISO 5625 wasdeveloped by Technical Committee ISO/TC 8, Shipbuilding, and was circulated to the member bodies in April 1977. It has been approved by the member bodies of the following countries : Australia France Norway Germany Austria Philippines India Belgium Romania Brazil Italy Spain Bulgaria Japan Turkey Chile Korea, Dem. P. Rep. of United Kingdom Czechoslovakia Yugoslavia Korea, Rep. of Finland Netherlands The member bodies of the following countries expressed disapproval of the document on technical grounds : Poland U.S.S.R. @ International Organization for Standardization, 1978 Printed in Switzerland t license from IHS Not for Resale ISO 5625-1978 (E) INTERNATIONAL STANDARD Shipbuilding - Welded bulkhead pieces with flanges for steel pipework - PN 6, PN 10 and PN 16 SCOPE This International Standard specifies the main manufac- turing dimensions of welded bulkhead pieces with flanges used in shipbuiding. It also specifies the corresponding openings to be provided in bulkheads and decks. D 2 FIELD OF APPLICATION This International Standard concerns exclusively those pieces fabricated and attached by welding, to be used with flanges in accordance with iso 2084 for pressure ratings 7 PN 6, PN 10 or PN 16. It does not specify the type of flange, the welding details, 7 or the radi of butt-welding bends. NOTE - Users of this International Standard should note that For dimension D1, see ISO 2084 while observing the requirements of this International Standard they should at the same time ensure compliance with such statutary requirements, rules and regulations as may be applicable to the FIGURE 1 - Type A individual ship concerned. 3 REFERENCE ISO 2084, Pipeline flanges for general use -- Metric series - Mating dimensions. 4 TYPES Figures 1 and 2 define standardized types : type A; type B. 4.1 Type A Type A is used where pipe connection is achieved using flanges on both sides of the bulkhead or deck (see figure 1). 4.2 Type B Type B is used where pipe connection is achieved using a flange on one side of the bulkhead or deck and a weld on the other side, whether a straight pipe or a butt-welding bend is used. For dimension D1, see ISO 2084. The type represented in figure 2 is assembled with a butt- welding bend for illustration purposes.
