EN 1514-2:2005 (E) 3 Foreword This European Standard (EN 1514-2:2005) has been prepared by Technical Committee CEN/TC 74 “Flanges and their joints”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2005, and conflicting national standards shall be withdrawn at the latest by November 2005. This document supersedes EN 1514-2:1997. EN 1514 consists of the following parts, Flanges and their joints - Dimensions of gaskets for PN-designated flanges: Part 1: Non-metallic flat gaskets with or without inserts; Part 2: Spiral wound gaskets for use with steel flanges; Part 3: Non-metallic PTFE envelope gaskets; Part 4: Corrugated, flat or grooved metallic and filled metallic gaskets for use with steel flanges; Part 6: Covered serrated metal gaskets for use with steel flanges; Part 7: Covered metal jacketed gaskets for use with steel flanges; Part 8: Polymeric O-Ring gaskets for grooved flanges. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Den-mark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxem-bourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

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 standard 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 being 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 Standard. Such gaskets may be available, however, for these types of flanges and the purchaser is advised to consult the manufacturer as to their availability. SIST EN 1514-2:2005
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 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, EN 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 documents are indispensable for the application of this document. For dated refer-ences, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 1333, Pipework components — Definition and selection of PN. EN ISO 6708, Pipework components — Definition and selection of DN (nominal size) (ISO 6708:1995). 3 Terms and definitions For the purposes of this European Standard, the following terms and definitions apply. 3.1 DN see EN ISO 6708 3.2 PN see EN 1333 4 Designations 4.1 Essential Features and Dimensions 4.1.1 General A major feature of the design of spiral wound gaskets to the requirements of this European Standard is the mini-misation of the possibility of the inner ring protruding into the bore of the pipe to which the flange is attached. The fit of the inner ring and sealing element relative to the outer ring has been selected to comply with this objective.
The essential features of a spiral wound gasket in compliance with this specification are given in Figures 1 and 2 and/or are listed below. Movement of centre of inner ring relative to guide ring Up to DN 200 a maximum of 0,2 mm
