Current Guidance and Best Practices Webinar

Electrohydraulic control (EHC) systems regulate the flow of steam into and output from steam turbine generators. These critical systems employ phosphate ester-based fluids as a result of their favorable hydraulic and fire-resistant properties. Like other lubricants, phosphate esters degrade during service. To ensure the performance and reliability of critical control systems, effective fluid maintenance is, therefore, required.

To assist EHC users, OEMs and other stakeholders offer documents that summarize recommended practices. Of these, ASTM D8323 was published in 2020 and is the most recent. This Standard provides detailed guidance for phosphate ester users on many aspects of fluid maintenance including conditioning and condition monitoring.

This presentation will highlight key points from D8323 with a particular focus on more recent breakthroughs in phosphate ester analysis and maintenance that are not present in older standards and OEM documents. It is important for phosphate ester users and other stakeholders (OEMs, fluid manufacturers, oil analysis labs, filtration vendors etc.) to understand current best practices so that they can work together to ensure the performance and reliability of critical production assets.
