26、AC:2004(E)41 ScopeThis European Standard specifies requirements for circular copper alloy flanges and copper alloy collars combined withloose steel plate flanges in PN designations from PN 6 to PN 40 and nominal sizes from DN 10 to DN 1800 in the typesshown in Table 1.This standard also specifies di
27、mensions 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 i
28、ntegral(type 21)flanges,are for attachment to copper or copper alloytubes in accordance with EN 12449.NOTE 1When the flanges specified in this standard are required for use with copper or copper alloy tubes to EN 1057 in thosetube diameters which are different to EN 12449,this should be agreed betwe
