Overview

EN 1514-8:2004 is a European standard developed by CEN that specifies the dimensions of polymeric O-Ring gaskets designed for use with grooved flanges. These flanges comply with EN 1092 and cover pressure ratings PN 10, PN 16, PN 25, and PN 40. The document is part of a comprehensive series dealing with flange gaskets for PN-designated flanges, each addressing different gasket types and applications.

This standard plays a crucial role in ensuring compatibility and interchangeability of polymeric O-Ring gaskets with grooved flanges, supporting consistent sealing performance across various industrial piping systems. It also provides guidelines on ordering information to ensure correct material selection based on operating conditions.

Key Topics

  • Scope and Applicability
    EN 1514-8:2004 applies to polymeric O-Ring gaskets intended for grooved flanges with specific PN pressure designations-PN 10, 16, 25, and 40.

  • Dimensions and Tolerances
    The document defines precise gasket dimensions including nominal diameter (DN), inside diameter, annulus diameter, and allowable manufacturing tolerances essential for reliable sealing. The standard covers a wide range of nominal diameters from DN 10 up to DN 3000.

  • Designations and Marking
    Gasket designation includes nominal diameter, PN rating, and polymer type to clearly identify gasket specifications. An example format:
    Gasket EN 1514-8 - 150 - 10 - polymer type

  • Material Selection Guidance
    Selecting the appropriate polymeric material is critical for gasket performance under specific temperature and fluid conditions. The standard recommends purchaser-supplier consultation to determine the optimal polymer material.

  • Packaging Requirements
    Packaging must adequately protect the gaskets from damage during transport and handling prior to installation.

  • Ordering Information (Annex A)
    Annex A outlines essential details that purchasers should provide, such as the document number, DN, PN rating, and desired polymer material or operating conditions to assist suppliers in providing the correct gasket.

Applications

EN 1514-8 polymeric O-Ring gaskets are widely used in industries where flanged pipe connections require reliable sealing under pressure, including:

  • Water and wastewater treatment
  • Chemical processing plants
  • Oil and gas pipelines
  • Food and beverage manufacturing
  • Pharmaceutical industry
  • HVAC and industrial heating systems

These gaskets offer enhanced sealing for grooved flange assemblies, known for ease of installation, durability, and compatibility with pressurized systems. Proper gasket selection and sizing according to this standard ensure tight seals, reduce leaks, and support system safety and efficiency.
