Steam turbine valves are typically so reliable they are often overlooked. However, the inspection and maintenance of these valves is critical. In today’s increasingly competitive energy market, major turbine inspection intervals have been extended. In some cases, maintenance planners or plant operators also extend turbine valve inspection and maintenance to coincide with turbine major inspections. This has often resulted in valve failures and steam turbine over speed events, some of which have been catastrophic. Risk exposures associated with untimely or improper steam turbine valve maintenance include:

• Downstream steam path damage due to debris and solid particle erosion

• Oil leaks resulting in fire under valve areas

• Complete destruction of the unit from over speed, including likely fire and hydrogen explosion resulting from over speed energy release

Failure to perform timely inspections and maintenance can lead to the total destruction of a steam turbine generator as a result of a valve not functioning and closing as required. This course is designed to provide participant with a detailed and up-to-date overview of STEAM TURBINE VALVES inspection and testing in accordance with API 598. It covers the API requirements needed to perform inspection, examination, supplementary examinations and pressure testing requirements for resilient-seated, non-metallic-seated and metal-to-metal-seated valves of the gate, globe, plug, ball, check and butterfly types.

During this course, participants will learn to inspect, examine and perform supplementary examination; carryout pressure testing, Identify test location, test equipment and test required; differentiate high-pressure closure test and high-pressure pneumatic test; identify test fluid; test pressures, test duration and test leakage; employ pressure testing procedures including backseat testing, shell testing, low-pressure and high-pressure closure testing, double block and bleed high-pressure closure testing; and explain in details the valve certification and retesting.

Upon completion of this course, the participants shall be able to:

• Apply and gain an-depth knowledge on valve inspection and testing in accordance with the international standard API 598

• Inspect, examine and perform supplementary examination covering inspection of valve manufacturer’s plant, inspection notice and extent of inspection

• Carryout pressure testing as well as identify test location, test equipment and tests required

• Differentiate high-pressure closure test and high-pressure pneumatic test

• Describe test fluid, test pressures, test duration and test leakage

• Employ pressure testing procedures including backseat testing, shell testing, low-pressure and high-pressure closure testing, double block and bleed high-pressure closure testing

• Explain in details the valve certification and retesting comprising of certificate of compliance and retesting

This course provides a wide understanding and deeper appreciation for an overview of all significant aspects and considerations of valve inspection and testing in accordance with the international standard API 598 for process, piping, pipelines and pressure vessels engineers and supervisors. Further, it is suitable for inspection and QA & QC engineers, boilers and process plant equipment owners, maintenance staff who inspect and install pressure relief devices and engineers involved in plant turnaround and upgrade projects.

• The BK Management Team believes that learning is not only about acquiring technical skills, it is also about learning behaviors & Competencies that are desirable for work in plant operation & maintenance, critical dimensions. Our holistic teaching develops our delegates' personal effectiveness to function both as individuals and as team players.

• The course delivery & modes of instruction will incorporate Hands-on Practical Sessions using equipment, State-of-the-Art Simulators (as required), Drawings, Case Studies, Videos, Exercises, Theory, Practical skills, and Q&A sessions.

• To enhance learning outcomes, theory sessions will comprise classroom-based lectures that will be interspersed with interactive discussions, scenario-based, case-study, group exercises, video clips, PowerPoint slides, learners' Guide, and the application of various tools, which will be provided to help the delegates and participants of the learning objectives. With the successful implementation of the learnt skills, they are bound to enhance Individual & Organizational growth.

• For online / Interactive Virtual sessions, the Delegate should have a stable & good Internet connection on their Laptop.
