Overview
ISO 24239:2022 - Corrosion control engineering life cycle in fossil fuel power plants: General requirements provides a structured, life‑cycle approach to controlling corrosion in all types of fossil fuel power plants. The standard defines general requirements for every life‑cycle element - from design, materials selection and manufacturing through commissioning, operation, maintenance, overhaul and final disposal - with the aim of ensuring safe, economical, long‑term and environmentally responsible plant operation.
Key Topics and Requirements
- Life‑cycle coverage: Specifies requirements across all stages (design, R&D, manufacturing, storage/transportation, construction, commissioning, acceptance, operation, maintenance, overhaul, scrapping/disposal, documents and records, resource management and comprehensive assessment).
- Corrosion source identification: Procedures for identifying internal and external corrosion sources (e.g., atmosphere, flue gas, water, steam, molten salts, acid/alkali, soil, impurities in oil or gas) and for assessing environmental impacts such as temperature, pressure, flow and stress.
- Materials selection: Systematic process to determine service environment, choose corrosion‑resistant materials, refer to relevant standards/manuals, and validate selections via references, laboratory simulation or field tests. Material review and assessment procedures are required.
- Corrosion modes addressed: Includes high‑temperature fire‑side corrosion, high‑temperature steam corrosion, flow‑accelerated corrosion (FAC), stress corrosion, low‑temperature (acid dew point) corrosion and lay‑up corrosion.
- Technical measures: Emphasizes water and steam quality regulation and control, combustion adjustment and other engineered controls (Annex C provides examples of typical corrosion control technologies).
- Organizational controls: Calls for a corrosion control oversight system, defined roles (owner, technical management, operations, maintenance) and clear responsibilities to enable coordinated, continuous improvement (illustrated in Annex B).
- Documentation and assessment: Requires records, procedures and comprehensive assessment practices to verify ongoing suitability and effectiveness.
Applications and Who Uses It
ISO 24239:2022 is used by:
- Plant owners and operators seeking to reduce corrosion‑related failures and lifecycle costs
- Engineering, procurement and construction (EPC) firms for design and material specifications
- Materials engineers, corrosion specialists and maintenance teams for selection and inspection programs
- R&D groups developing corrosion‑resistant solutions and testing protocols
- Regulators and asset managers establishing compliance and safety frameworks
Practical benefits include improved reliability, extended equipment life, optimized maintenance planning, reduced downtime and enhanced environmental protection.
