18、1092-3:2003/AC:2004 (E) 3 Foreword Due to the incorrect hatching, all figures were replaced. This document (EN 1092-3:2003) has been prepared by Technical Committee CEN/TC 74 “Flanges and their joints“ the secretariat of which is held by DIN. This European Standard shall be given the status of a nat
19、ional standard, either by publication of an identical text or by endorsement, at the latest by March 2004, and conflicting national standards shall be withdrawn at the latest by March 2004. This document has been prepared under a mandate given to CEN by the European Commission and the European Free
20、Trade Association, and supports essential requirements of the Pressure Equipment Directive (PED) 1) . For relationship with EU Directive(s), see informative annex ZA, which is an integral part of this standard. EN 1092 consists of the following parts: Part 1: Steel flanges; Part 2: Cast iron flanges
21、; Part 3: Copper alloy flanges; Part 4: Aluminium alloy flanges. The annexes A, B, C and ZA are informative. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Cze
22、ch Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and the United Kingdom. Introduction This standard is related to ISO 7005-3 in respect of flanges having the same
23、PN. The types of flanges and their mating dimensions are identical with those flanges of the same DN and PN given in ISO 7005-3, except that certain flange types in accordance with this standard may regularly be supplied with raised face facings. The mating dimensions of the flanges of this standard
24、 are compatible with PN designated flanges of other materials in accordance with the other parts of EN 1092.1) Directive 97/23 EC of the European Parliament and of the Council of 29 May 1997 on the approximation of the Laws of the Member States concerning pressure equipment; OIEC L 181.

26、ations from PN 6 to PN 40 and nominal sizes from DN 10 to DN 1800 in the types shown in Table 1. This standard also specifies dimensions and tolerances, materials and their associated pressure/temperature (p/T) ratings, flange facings and related surface finish, weld repairs, and marking, together w
27、ith information on bolting, gaskets, application/installation and approximate flange masses. The flanges specified, with the exception of integral (type 21) flanges, are for attachment to copper or copper alloy tubes in accordance with EN 12449. NOTE 1 When the flanges specified in this standard are
28、 required for use with copper or copper alloy tubes to EN 1057 in those tube diameters which are different to EN 12449, this should be agreed between the equipment manufacturer and the flange manufacturer. NOTE 2 The size of copper and copper alloy tubes is designated by reference to the outside dia
29、meter in millimetres. NOTE 3 See also annex B. NOTE 4 Non-gasketed pipe joints are outside the scope of this standard. Table 1 Types of flanges and collars Type no.
