TG316 – Steam Turbine Overhauls & Repairs

4.5 days - 32 PDH Credits Awarded

$2,495.00

Description

We all want to improve the effectiveness of steam turbine maintenance activities. This course is an important step toward accomplishing this goal. Collectively, we want to: REDUCE: Outage Durations, Outage Extensions, Work Duplication, and Rework. INCREASE: Outage Intervals, Reliability, Availability, and Productivity. Extensive "Training Aids" exercises are utilized during the entire 4 1/2-day session.  This course is presented at our facility in Bradenton, FL due to extensive uses of steam turbine components for practical exercises. This course has been designed for steam turbine facility foremen, supervisors, mechanics, engineers, and all other plant personnel who are concerned with increasing the effectiveness and reducing the cost of steam turbine/generator maintenance outages.  A thorough understanding of turbine fundamentals is a prerequisite for this course.  This basic knowledge may be obtained by "On-Job" experience or by completion of a turbine fundamentals course. Topical Outline includes: Diaphragm Area Checks, Diaphragm Drop Checks, Diaphragm Repairs, Steam Path Audit, Bucket/Blade Repair, Shell / Casing Repair, Bearing Repairs, Valve Component Repairs, and Packing / Seal / Fitting Repairs as-well-as stationary and rotating component repairs.
