28、Class 150; Class 300; Class 600; Class 900; Class 1 500; Class 2 500. 4.2 Range of gasket sizes Gasket nominal sizes shall be designated in accordance with Table 1. 4.3 Gasket types Gasket types, as defined in clause 5 and illustrated in Figure 2, shall be designated as either “oval” or “octagonal”.
29、 4.4 Identification number Each metallic ring-joint gasket is assigned an identification number, prefixed by “R”, as shown in Table 1. NOTE The nominal size(s) and Class designation(s) to which each identification number is relevant is given in Table 1. 4.5 Information to be supplied by the purchase
30、r The following information shall be supplied by the purchaser when ordering gaskets: a) the number and Part of this European Standard, i.e. EN 12560-5; b) whether a particular cross-sectional shape i.e. oval or octagonal, is required (see clause 5); c) the identification ring number (see 4.4 and Ta
31、ble 1); d) the material (see annex A);Additional information that should be supplied by the purchaser : e) the expected operating conditions for which the gasket will be used. NOTE Before ordering a gasket it is recommended that the selection of the gasket type shall be made in consultation with the
32、 gasket supplier. The selection of gasket type should take account of the fluid, the operating conditions, the properties of the gasket materials, the type and surface finish of the flange facing and the flange bolt loading. EXAMPLE A gasket according to EN 12560-5, oval type, with ring number R.36
33、in type X12Cr13 (Identification symbol S 410) shall be designated as follows : Gasket EN 12560-5 oval R.36 S 410.Page 7 EN 12560-5:2001 BSI 03-2001 5 Gasket types Metallic ring-joint gaskets for use with ring-joint (type J) flange facings complying with prEN 1759-1:2000 shall have a cross-sectional
34、shape that is either oval or octagonal. NOTE 1 Figure 1 a) shows a flange joint with an oval type gasket and Figure 1 b) with an octagonal type gasket. NOTE 2 Figure 2 shows the design of oval type and octagonal type gaskets. NOTE 3 Ring-joint gaskets of individual identification numbers are applica
35、ble to certain nominal size(s) and Class designation(s), as given in Table 1. NOTE 4 If the purchaser requires a ring-joint gasket with a particular cross-sectional shape, i.e. either oval or octagonal, then this requirement should be stated in the enquiry and/or order (see 4.5). In the absence of t
36、his requirement being stated, the type will be at the discretion of the manufacturer. NOTE 5 The selection of the gasket should take into account the fluid, the operating conditions, the properties of the gasket materials, the type and surface finish of the flange facing and the flange bolt loading.
37、 It is recommended that selection of gaskets for any particular application is made in consultation with the gasket supplier (see 4.5).Page 8 EN 12560-5:2001 BSI 03-2001 a) oval type b) octagonal type Figure 1 Details of metallic ring-joint gaskets as housed Key A Width of ring B Oval C Width on fla

39、Figure 2. NOTE Dimensions of grooves and gaskets are such that, when joints are assembled, the flanges are apart and the approximate distances which the flanges are apart for each Class designation are given in the appropriate table of prEN 1759-1:2000. 6.2 Tolerances The tolerances given in Table 2
40、 shall apply for the dimensions as shown in Figure 2. NOTE The presence of a small forging fin, located so that it does not prevent the ring from seating properly in the groove, is acceptable.Page 10 EN 12560-5:2001 BSI 03-2001 Table 1 Ring numbers and dimensions of metallic ring-joint gaskets Flang
