An equipment manufacturermay require a certificate in accordance with EN 10204 which is suitable for the category of the equipment to whichthe flange is fitted.NOTEIf a protective coating such as zinc coating or painting is required on steel components, the equipment manufacturershould state this on the enquiry and/or order.5.2 Repairs5.2.1Repairs by welding are permitted when there is a proven method and where not otherwise prohibited bythe applicable material standard.
All welding shall be carried out in accordance with a written procedure.NOTEFor approval of welding procedures, see EN 288-1. For approval of welders, see EN 287-1.5.2.2Any filler rod used for weld repairs shall be such as to produce a weld having characteristics at least equalto the parent metal. Flanges shall be heat treated after repair welding when the material standard requires suchtreatment.5.3 BoltingFlanges shall be suitable for use with the nominal size and number of bolts specified in Tables 4 and 5 as appropriate.The bolting material shall be chosen by the equipment manufacturer according to the pressure, temperature, flangematerial and the selected gasket so that the flanged joint remains tight under the expected operating conditions.NOTE 1For information on bolting, see EN 1515-1 and EN 1515-2 and annexes B and C.NOTE 2For flange types 01, 05, 11, 12, 14 and 21, where copper alloy bolting is used, the recommended bolting materialsare EN 12420 Alloy Nos. CW306G or CW307G for temperatures up to and including 120°C.For flange types 04, 05C and 07, steel bolting should be used and reference should be made to EN 1515-1, EN 1515-2and annex C.5.4 GasketsThe various gasket types, dimensions, design characteristics and material used are not within the scope of thisstandard. Dimensions of gaskets are given in the relevant parts of prEN 12560.5.5 Pressure/temperature (p/T) ratings5.5.1 GeneralThe p/T ratings of the flanges manufactured from the materials specified in Tables 7 and 8 are given in Tables 9, 10and 11.The p/T ratings indicate the relationship between the maximum allowable pressure, PS and the maximum allowabletemperature, TS.Linear interpolation is permitted for intermediate temperatures.SIST EN 1759-3:2004/AC:2005
EN 1759-3:2003/AC:2004 (E)9NOTE 1See EN 764 for terminology.NOTE 2When type 21 flanges are supplied as part of another component (for example, a valve or pump) in a material otherthan those listed in Table 7, reference should be made to the relevant product or application standard for the appropriate p/Tratings.NOTE 3The p/T rating of a flange is not necessarily the p/T rating of the whole pipework system. Gasket materials can alsoimpose a limitation of the p/T rating of a flanged joint and the gasket manufacturer should be consulted when selecting thematerial of the gasket.5.5.2 p/T ratings of flanged jointsWhen two flanges in a flanged joint do not have the same p/T rating at any temperature, then the lower of the twoflange p/T ratings at that temperature shall apply.NOTE 1For any p/T rating, the temperature shown is considered to be the same as that of the contained fluid. Use at apressure corresponding to a temperature other than that of the contained fluid is the responsibility of the user.NOTE 2Application of the p/T ratings given in this standard to flange joints should take into consideration the risks ofleakage due to forces and moments developed in the connecting pipework, see annex B.NOTE 3These notes on service considerations are not intended to be exhaustive.5.6 Dimensions5.6.1 FlangesDimensions of flanges shall be in accordance with the following tables and figures as appropriate: Class 150 flanges: Table 4 and Figure 2; Class 300 flanges: Table 5 and Figure 3.NOTE 1The bore sizes of type 21 flanges are usually equal to the nominal size of the pipe, valve or fitting of which they form apart and the actual bore sizes are usually given in the appropriate standard(s) for the pipe, valve or fitting.NOTE 2When type 07, 12 and 14 flanges are for use with soft soldering techniques only, then reference should be made toEN 1254-1 for socket depths.NOTE 3For type 34 collars and type 11 flanges the recommended weld preparation angle is 37,5 ± 2,5° when butt welding topipe with thickness of 3 mm and greater.5.6.2 Bolt holesBolt holes shall be equally spaced on the pitch circle diameter. In the case of type 21 flanges, the bolt holes shall bepositioned such that they are symmetrical to the principle axes and such that no holes fall on these axes, i.e. positioned"off-centre", see Figures 2 and 3.5.7 Flange facings5.7.1 Types of facingsTypes 01, 05, 11, 12, 14 and 21 flanges in copper alloy shall be provided with flat face.NOTE 1Flanges with flat face facings are suitable for bolting to flat face mating flanges using a full face gasket.Types 04, 05C and 07 flanges have a raised face formed by the face of the collar or the cladding, for bolting to raisedface mating flanges using an inside bolt circle gasket.NOTE 2The bolting of these flanges to a flat face iron or steel mating flange using full face or inside bolt circle gaskets is notprecluded.SIST EN 1759-3:2004/AC:2005

The abutment faces shall be flat and square to the bore axis.5.8 Spot facing or back facingAny spot facing or back facing required shall not reduce the flange thickness to less than the minimum specified.When spot facing is used, the diameter shall be large enough to accommodate the outside diameter of the equivalentnormal series of washers complying with EN ISO 887 for the bolt size being fitted.When a flange is back faced, it is permissible for the fillet radius to be reduced but it shall not be eliminated entirely.The bearing surfaces for the bolting shall be parallel to the flange jointing face within the limits given in Table 6.5.9 TolerancesTolerances on dimensions shall be as specified in Table 6.5.10 Marking5.10.1 Other than type 21 flangesAll flanges and collars shall be marked as follows:a) Number of this
