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.

Over the past couple years the most commonly received comment for our traditional steam turbine and valve maintenance training was, "I wish I had taken this course 10-years ago."  Well, we’re planning on the same comments for the VILT (virtual instructor led training) sessions.  The phrase high-quality applies to ‘content’ and the ‘presentation’ skills.  We see the following advantages in the delivery of our virtual instructor led training session:

  • Greater schedule flexibility since we don’t have to deal with travel schedules.
  • Lesser cost as there is the travel & living expenses is now zero.
  • Lesser time consumption as travel time to / from the site or classroom is eliminated.
  • Maintain the same level of content (sometimes even improve that content) by greater attention given to the need for a quality presentation.
  • Improved even more easy to read text content.

All of the above advantages along with HPC’s history of providing knowledgeable / equipment experienced instructors

Objectives

Upon completion of the course the participants should be able to, on (GE) fossil steam turbines:

  1. Identify safety precautions that must be adhered to during a turbine steam valve inspection and repair outage.
  2. Describe the disassembly of, and various inspections performed during disassembly of turbine steam valves.
  3. Describe the procedures for cleaning and inspecting the turbine steam valve components.
  4. Describe the impact of the various types of defects on turbine efficiency and reliability.
  5. Describe the criteria used to evaluate turbine steam valve component defects.
  6. Describe the various repair methods for defective steam valve component conditions.
