Overview

EN 1514-4:1997 is a CEN standard that specifies the dimensions and marking of inside-bolt-circle (IBC) corrugated, flat or grooved metallic and filled metallic gaskets for use with steel flanges. It applies to gaskets intended for flanges complying with EN 1092‑1 and covers pressure designations PN 10, PN 16, PN 25, PN 40, PN 63 and PN 100, for nominal diameters up to and including DN 900. This part of the EN 1514 series ensures dimensional interchangeability and consistent marking for metallic gasket types used with PN-designated flanges.

Key topics

  • Scope and applicability: Gaskets covered are metallic (corrugated, flat, grooved) and filled metallic types for steel flanges meeting EN 1092‑1, for PN-rated systems up to DN 900.
  • Inside bolt circle (IBC) dimensions: Standardizes the critical gasket dimensions relative to the flange bolt circle to ensure compatibility and correct sealing behavior.
  • Marking requirements: Defines marking conventions so gaskets are identifiable by type and size, supporting traceability and correct selection.
  • Compatibility with PN flanges: Aligns gasket dimensions with the PN pressure-rating system (PN 10–100) used in European flange standards.
  • Seal type coverage: Addresses corrugated metallic gaskets, flat metallic gaskets, grooved metallic gaskets and filled metallic designs - enabling selection based on application demands (temperature, pressure, media).

Applications

EN 1514-4 is used where reliable flange joints and standardized gasket interchangeability are required:

  • Pipeline and process industries: oil & gas, petrochemical, chemical and refinery piping systems.
  • Power generation and utilities: steam, condensate and high-pressure systems.
  • Water and wastewater systems: pressure-rated steel flanged connections.
  • Industrial fabrication and maintenance: flange manufacturers, gasket producers, piping designers, mechanical engineers, maintenance teams and procurement. Using EN 1514-4 helps ensure correct gasket sizing, reduced leakage risk, simplified spare-parts management and regulatory compliance for PN-designated flanged joints.

Related standards

  • EN 1092‑1 - Steel flanges (the flange standard with which EN 1514‑4 gaskets must be compatible).
  • Other parts of the EN 1514 series (for dimensions and marking of different gasket types and configurations).

Keywords: EN 1514‑4, gaskets, flanges, PN flanges, EN 1092‑1, corrugated gasket, metallic gaskets, filled metallic gaskets, IBC dimensions, DN 900.
