Abstract

This European Standard specifies the construction, dimensions and marking of covered serrated metal gaskets for use with flanges complying with EN 1092-1 for PN 10, PN 16, PN 25, PN 40, PN 63 and PN 100 up to and including DN 3000.
This document does not extend to covered serrated metal based heat exchanger gaskets with pass bars or large vessel gaskets but, in the lack of a dedicated document for such gaskets, the principles set down can be applied to them.
NOTE 1   Dimensions of other types of gaskets for use with flanges to EN 1092-1, EN 1092-2, prEN 1092-3 and EN 1092-4 are given in EN 1514-1, EN 1514-2, EN 1514-3, EN 1514-4, prEN 1514-7 and prEN 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.

Overview

EN 1514-6:2003 (CEN) defines the construction, dimensions and marking of covered serrated metal gaskets intended for use with steel flanges complying with EN 1092-1. The standard covers PN-designated flanges for pressure ratings PN 10, PN 16, PN 25, PN 40, PN 63 and PN 100, and applies to nominal diameters up to and including DN 3000. Published by CEN in 2003, this part of the EN 1514 series standardizes gasket geometry and identification to ensure interchangeability and reliable sealing performance in industrial piping and equipment.

Key Topics

  • Scope and applicability
    • Covered serrated metal gaskets for steel flanges per EN 1092-1
    • Applicable PN classes and DN sizes (up to DN 3000)
  • Construction requirements
    • Requirements for gasket construction and covered serrated profile (general geometric/constructive definition provided)
  • Dimensions
    • Standardized gasket dimensions to match PN-designated flange faces (ensures compatibility and interchangeability)
  • Marking and identification
    • Marking rules to identify gasket type, size and other relevant information for traceability
  • Limitations and exclusions
    • Does not extend to metal-based heat exchanger gaskets with pass bars or very large vessel gaskets, though the standard’s principles can be applied where a dedicated document is absent
  • Purchaser information (Annex A)
    • Lists information purchasers should supply when ordering gaskets if material selection is left to the supplier

Applications

EN 1514-6:2003 is intended for professionals who specify, design, manufacture, procure or maintain flange joints and gaskets in sectors such as:

  • Oil & gas and petrochemical piping systems
  • Power generation and utility plants
  • Water and wastewater infrastructure
  • Chemical processing and refineries
  • General industrial piping and pressure equipment

Typical uses include specifying covered serrated metal gaskets for steel flange connections where standardized dimensions, reliable sealing and clear marking are required.

Who Uses This Standard

  • Piping and mechanical engineers
  • Gasket and flange manufacturers
  • Procurement and specification writers
  • Pressure system inspectors and maintenance teams
  • Design offices and OEMs working with PN-designated steel flanges

Related Standards

  • EN 1092-1 (steel flanges) - primary flange standard for which these gaskets are intended
  • Other parts of EN 1514: EN 1514-1, EN 1514-2, EN 1514-3, EN 1514-4, prEN 1514-7, prEN 1514-8 - dimensions for other gasket types
  • EN 1092-2 to EN 1092-4 - additional flange materials/types
