    Scope - (Show below) - (Hide below)

    This European Standard specifies requirements for circular copper alloy flanges and copper alloy collars combined with loose steel plate flanges in PN designations 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 with 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 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 diameter 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. Description 01 Plate flange in copper alloy for brazing or welding 02 Loose plate flange in steel with a plate collar (type 32) in copper alloy, for brazing or welding. 04 Loose plate flange in steel with a weld-neck collar (type 34) in copper alloy, for welding. 05 Blank flange in copper alloy. 05C Blank flange in steel clad with a copper alloy jointing face. 07 Loose plate flange in steel with a slip-on collar (type 37) in copper alloy, for soft soldering, brazing or welding. 11 Weld-neck flange in copper alloy for welding. 12 Hubbed slip-on flange in copper alloy, for soft soldering, brazing or welding. 14 Hubbed slip-on flange in copper alloy supplied with tube smiddles, for soft soldering, brazing or welding. 21 Integral flange in copper alloy as part of some other equipment or component 32 Plate collar in copper alloy 34 Weld-neck collar in copper alloy. 37 Slip-on collar in copper alloy.
