Guide for procurement of power station plant, equipment and systems - Part 7-2: Pipework and valves - Boiler and high pressure piping valves
General Information
Overview
EN 45510-7-2:1999 - Guide for procurement of power station plant, equipment, and systems (Part 7-2: Pipework and valves - Boiler and high pressure piping valves) provides guidance for writing technical specifications when procuring boiler and high-pressure piping valves, including safety valves, for electricity generating stations. The guide focuses on valve procurement for boiler plants (water-tube boilers, shell boilers, boilers with fluidized-bed firing) and high-pressure piping systems. It is expressly not applicable to equipment for use in the nuclear reactor plant area of nuclear power stations.
Key topics and requirements
The standard assists specification writers and procurement teams by addressing practical technical elements commonly required in power-station valve procurement. Key topics typically covered include:
- Scope and application: defining valve types covered (including safety valves) and exclusions (nuclear reactor plant area).
- Technical specification structure: recommended clauses and wording to ensure complete, unambiguous procurement documents.
- Design and materials: guidance on specifying materials suitable for boiler and high-pressure piping environments (temperature, corrosion, erosion considerations).
- Performance and ratings: how to require appropriate pressure-temperature ratings, flow characteristics and leakage limits.
- Testing and inspection: recommended factory tests, site testing and acceptance criteria to verify valve performance.
- Documentation and marking: required certificates, drawings, operating and maintenance instructions, traceability and marking.
- Quality assurance and compliance: specifying manufacturer qualifications, QA procedures and conformity evidence.
- Safety valves: guidance for defining performance, setpoints, discharge capacity and maintenance requirements specific to overpressure protection.
(Note: the guide provides procurement guidance; it does not itself define test methods or detailed design rules beyond wording and specification recommendations.)
Applications
EN 45510-7-2 is practical for:
- Procuring valves for power plant boilers and high-pressure steam systems
- Preparing tender documents, purchase orders and technical specifications
- Ensuring consistent procurement requirements across large generating-station projects
- Supporting lifecycle considerations such as maintenance access, spares and documentation
Who should use this standard
- Procurement and contract engineers in power utilities and independent power producers
- Specification writers and project engineers for boiler and steam piping systems
- EPC contractors and consulting engineers preparing tender packages
- Valve manufacturers and suppliers responding to power-station tenders
- QA/QC and inspection teams verifying supplier conformity
Related standards
- Part 7-2 is one element of the EN 45510 series covering procurement guides for power station plant and systems. Users should cross-reference applicable valve and pressure-equipment standards and national regulations when specifying tests, materials and certification.
