EN 1514-2:2005 (E) 4 Introduction This European Standard replaces an earlier one issued in 1997. The reason for the revision is to ensure that the stand
20、ard reflects the current practice within the German Chemical Industry. The dimension of the various components of the spiral wound gaskets described and their tolerances have been set with the objective of controlling the possibility of protrusion of the inner ring into the bore of the pipeline bein
21、g sealed. The other features of the standard have been set in order to ensure good functionality of spiral wound gaskets made to this European Standard. The dimensions of spiral wound gaskets for tongue and groove flanges and spigot and recess flanges to EN 1092-1 are not included in this European S
22、tandard. Such gaskets may be available, however, for these types of flanges and the purchaser is advised to consult the manufacturer as to their availability. EN 1514-2:2005 (E) 5 1 Scope This European Standard specifies the dimensions and marking of spiral wound gaskets for use in conjunction with
23、flat face and raised face flanges complying with EN 1092-1 for PN 10, PN 16, PN 25, PN 40, PN 63, PN 100 and PN 160 and up to and including DN 1000. NOTE 1 Dimensions of other types of gaskets for use with flanges to EN 1092-1, EN 1092-2, EN 1092-3 and EN 1092- 4 are given in EN 1514-1, EN 1514-3, E
24、N 1514-4, EN 1514-6, EN 1514-7 and EN 1514-8. NOTE 2 Annex A lists information that should be supplied by the purchaser when ordering gaskets in circumstances where the choice of the gasket materials appropriate to the service is left to the supplier. 2 Normative references The following referenced
