TG314 -(W) Steam Turbine Valve Maintenance

TG314 -(W) Steam Turbine Valve Maintenance

Description

Improve the effectiveness of your steam turbine valve maintenance activities on GE units. REDUCE: Outage Durations, Outage Extensions, Work Duplication, and Rework. INCREASE: Outage Intervals, Reliability, Availability, and Productivity. Greater unit reliability and availability can be achieved through proper routine valve maintenance activity. Quality valve maintenance outages are the result of thorough job planning and a complete understanding of the equipment, specifications, and procedures. This course has been designed for facility foremen, supervisors, mechanics, engineers, and all other plant personnel who are concerned with increasing the effectiveness and reducing the cost of steam turbine valve maintenance outages.  HPC is prepared to instruct this course as developed by equipment-experienced instructors that offer a broad range of practical experience on numerous types and sizes of steam turbine-generators.
