Overview
EN 12560-5:2001 is a CEN standard that specifies requirements for metallic ring-joint gaskets (RTJ gaskets) intended for use with steel flanges. The document covers the dimensions, types, design, materials and marking requirements of metallic ring-joint gaskets that mate with flange facings of type J as defined for flanges complying with EN 1759-1. The scope includes Class-designated flanges 150, 300, 600, 900 and 1500 for nominal sizes up to and including NPS 24 (DN600), and Class 2500 up to and including NPS 12 (DN300).
Key Topics
- Gasket types and geometry: Defines the metallic ring-joint (RTJ) gasket forms compatible with type J flange facings.
- Dimensions and tolerances: Specifies dimensional envelopes and acceptable manufacturing tolerances for interchangeability.
- Design and materials: Sets requirements for gasket profile, cross-section and suitable metallic materials to ensure reliable sealing with steel flanges.
- Marking and traceability: Requires clear marking of gaskets for identification, material, size and class to support installation, inspection and procurement.
- Compatibility limits: Clarifies the class designations (150–2500) and nominal size (NPS/DN) ranges where the standard applies.
Applications
EN 12560-5:2001 is used wherever high-integrity metal-to-metal flange seals are required, particularly in systems requiring ring-type joint (RTJ) sealing:
- Oil & gas pipelines and processing facilities
- Petrochemical and chemical plants
- Power generation (high-pressure steam and feedwater systems)
- Pressure-containing piping and valve assemblies in heavy industry
- Fabrication shops and flange/gasket manufacturers for quality control and product specification
Typical users include piping designers, mechanical engineers, procurement & inspection teams, flange and gasket manufacturers, and plant maintenance personnel who need to select or verify RTJ gaskets for Class-designated steel flanges.
Related Standards
- EN 1759-1 - referenced flange specification for type J facings (compatibility requirement)
- EN 12560 series - series context for gaskets for Class-designated flanges
- ICS classifications: 23.040.80 (Seals for pipe and hose assemblies) and 23.040.60 (Flanges, couplings and joints)
EN 12560-5:2001 helps ensure consistent, interchangeable metallic ring joint gaskets for steel flanges, supporting safe sealing performance and simplified procurement across high-pressure piping applications.
