Overview

EN 45510-7-1:1999 (CLC) - Guide for procurement of power station plant, equipment and systems - Part 7-1: Pipework and valves - High pressure piping systems is a procurement guide intended to help owners, specifiers and contractors prepare technical specifications for high pressure piping systems used in electricity generating stations. The standard focuses on non‑nuclear areas of power stations and explicitly excludes equipment for the nuclear reactor plant area. It was adopted nationally (e.g., SIST EN 45510-7-1:2002).

Key topics

This Guide provides practical guidance on how to write procurement and technical specification documents for high pressure pipework and valves. Key topics covered or typically addressed in such a procurement guide include:

• Scope of application - clarification that the guide applies to high pressure systems in power stations (not nuclear reactor plant areas).
• Types of piping covered - live steam lines, hot reheat and cold reheat lines, feedwater lines, spray water lines for HP and RH attemperators, steam-bypass systems, pump minimum flow and balancing leak-off lines.
• Specification structure - recommended content and structure for technical specifications used in tendering and contracts.
• Performance and design considerations - guidance on expected functional requirements for high pressure pipework and valves (materials, pressure/temperature classes, and system interfaces) presented at a procurement level.
• Quality, testing and documentation - advice on requiring appropriate inspection, testing, traceability and manufacturer documentation to support procurement decisions.
• Interfaces and integration - considerations for how piping systems integrate with turbines, boilers, pumps and control systems in power stations.

Note: The Guide is procurement‑oriented and provides guidance rather than prescriptive engineering details.

Applications

Who uses EN 45510-7-1 and where it is applied:

• Procurement engineers and spec writers preparing tenders and contract technical specifications for power station projects.
• Plant owners/operators defining acceptance criteria for new installations or replacements.
• Manufacturers and suppliers of high pressure piping, valves and associated components responding to tenders.
• Consultants and engineering contractors designing system layouts and selecting components for fossil and combined‑cycle power plants.
• Maintenance and inspection teams referencing procurement expectations for spares and retrofits.

Keywords: EN 45510-7-1:1999, high pressure piping systems, pipework and valves, power station procurement, feedwater lines, steam bypass systems.

Related standards

• Other parts of the EN 45510 series (procurement guides for power station plant).
• National adoptions (e.g., SIST EN 45510-7-1:2002).
• Complementary EN/ISO standards for piping materials, valves and pressure systems (refer to project‑specific regulatory and safety standards).

This Guide helps translate operational and safety needs into clear procurement specifications for reliable high‑pressure pipework in electricity generating stations.
