Flanges and their joints - Circular flanges for pipes, valves, fittings and accessories, Class designated - Part 3: Copper alloy flanges
Abstract
This European Standard specifies requirements for circular copper alloy flanges and copper alloy collars combined with loose steel plate flanges in Class designations Class 150 and Class 300 and nominal sizes from DN 10 to DN 900 (NPS ½ to NPS 36) 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 with information on bolting, gaskets, application and 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 The size of copper and copper alloy tubes is designated by reference to the outside diameter in millimetres. NOTE 2 See also Annex B. NOTE 3 Non-gasketed pipe joints are outside the scope of this standard. Table 1 - Types of flanges and collars [Table 1 and Figure 1 not represented]
