General Information
Overview
EN 1514-7:2004 is a CEN European Standard that specifies the construction, dimensions and marking of covered serrated metal jacketed gaskets intended for use with steel flanges that comply with EN 1092-1. The standard covers PN-designated flanges from PN 2.5 up to PN 100, and flange sizes up to and including DN 900. It excludes certain specialised types (for example heat exchanger gaskets with pass bars and large vessel gaskets), though its principles may be applied where no dedicated document exists.
Key topics and requirements
- Scope of application: Gaskets for steel flanges per EN 1092-1 for PN classes 2.5, 6, 10, 16, 25, 40, 63 and 100 up to DN 900.
- Construction: Defines the covered serrated, metal-jacketed gasket form and the required construction elements (jacket, cover, serration/profile).
- Dimensions: Specifies dimensional requirements that ensure interchangeability and compatibility with PN-designated flanges.
- Marking: Details marking requirements so gaskets can be identified for material, size and conformity.
- Ordering information: Annex A lists purchaser-supplied information recommended when the supplier selects gasket materials appropriate to the service (service conditions, temperature, pressure, media).
- Application limitations: Notes exclusions (e.g., heat exchanger gaskets with pass bars) and advises that the standard’s principles may be applied to comparable special gaskets in the absence of a dedicated standard.
Applications
EN 1514-7:2004 is used to specify and select covered metal jacketed gaskets in industrial piping and flange connections where reliable sealing under pressure is required. Typical applications include:
- Oil & gas piping and flanged connections
- Chemical and petrochemical process lines
- Power generation plants and steam systems
- Water treatment and distribution
- Industrial HVAC and high-pressure utility lines
These gaskets are suited for services requiring robust metal-jacket protection with a covered/soft facing to improve sealing and chemical resistance.
Who uses this standard
- Flange and gasket manufacturers (design and quality control)
- Piping and mechanical engineers (specification and design)
- Procurement teams (ordering and supplier assessment)
- Plant operators and maintenance teams (replacement and compatibility checks)
- Certification and inspection bodies
