EN 1514-3:1997 - Flanges and their joints - Dimensions of gaskets for PN-designated flanges - Part 3: Non-metallic PTFE envelope gaskets

Overview

EN 1514-3:1997 - "Flanges and their joints - Dimensions of gaskets for PN-designated flanges - Part 3: Non-metallic PTFE envelope gaskets" is a CEN standard that defines the dimensions and marking requirements for inside-bolt-circle (IBC) non‑metallic envelope gaskets with a PTFE (polytetrafluoroethylene) envelope. The standard applies to gaskets intended for flanges manufactured to EN 1092 Parts 1–4, for pressure ratings PN 6 up to and including PN 63, and flange sizes up to and including DN 600.

Key topics

  • Scope and applicability: Specifies which flange types and nominal pressures (PN 6–63) and nominal diameters (≤ DN 600) are covered.
  • IBC gasket geometry: Defines the required inside-bolt-circle (IBC) format for non‑metallic PTFE envelope gaskets used with PN‑designated flanges.
  • Marking requirements: States how gaskets must be marked for identification and traceability (standard designation, material, size/PN as applicable).
  • Material class: Focus on PTFE‑enveloped non‑metallic gaskets, emphasizing their role as soft (non‑metallic) sealing elements.
  • Compliance references: Links gasket dimensions and marking to flanges conforming with EN 1092 Parts 1–4.

Note: EN 1514-3 establishes dimensional and marking conventions rather than prescribing specific performance test methods or installation procedures.

Applications

EN 1514-3 is used where corrosion resistance, chemical compatibility, and low-friction sealing are required. Typical application areas include:

  • Chemical and petrochemical process piping
  • Corrosive fluid handling systems
  • Pharmaceutical and food processing (where PTFE’s inertness is beneficial)
  • General industrial piping where PN‑designated flanges (PN 6–63) and DN ≤ 600 are used

Using PTFE envelope gaskets helps reduce medium contact with less resistant gasket cores and provides good chemical resistance and wide temperature compatibility.

Who uses this standard

  • Gasket and flange manufacturers for product specification and marking
  • Pipework designers and engineers specifying flange joints for PN ratings
  • Procurement and quality assurance teams verifying conformity
  • Maintenance and operations personnel selecting replacement gaskets
  • Regulatory and compliance officers ensuring installed components meet CEN requirements

Related standards

  • EN 1092 (Parts 1–4) - referenced flange standards for PN-designated flanges
  • Other parts of the EN 1514 series (for different gasket types and configurations)

EN 1514-3 is essential for anyone specifying or supplying PTFE envelope gaskets, ensuring consistent gasket dimensions, correct marking, and compatibility with PN‑designated flanges.
