Gas Piping Systems Fundamentals

A Training Seminar by KASA Redberg.

0 STUDENTS ENROLLED

     

    In-House sessions are available upon request.

     

    Introduction:

    Compressible flow offers some unique challenges when compared to liquid flow in pipes. This is due to the properties of gases and how these properties change depending on the piping system temperature, pressure and even flow velocity.

    The purpose of this two-day seminar is to provide information and guidance on the design of gas piping so that those new to gas piping systems can design such systems with minimal supervision.

     

    Who Should Attend:

    Consulting Engineers, Process Engineers, Design Engineers, Project Engineers, Sales Representatives and anyone who needs to have a greater understanding of the design and operation of gas piping systems including fuel gas, steam, compressed air and nitrogen etc.

    Delegate Pre-Requisites:

    As this seminar includes many system design calculations, it is recommended that each attendee is degree or diploma qualified in a relevant technical discipline (e.g. mechanical, chemical or mining engineering or physics, chemistry etc).

    For the maximum benefit to be obtained, it is recommended that each delegate:

    • Is familiar with basic hydraulics theory.
    • Has had some previous exposure to gas piping systems.
    • Has a basic understanding of the more common valve types.

    Those who have previously attended KASA’s “Liquid Piping Systems Fundamentals” seminars should also be well placed to derive maximum benefit from this seminar.

     

    Overlap With Other KASA Piping Seminars:

    This seminar has been designed so that it is attended after delegates have already completed KASA’s “Liquid Piping Systems Fundamentals” seminar. Because of this, any information relating to piping materials, piping connections, valves, instruments, drafting and hydraulics theory that is presented in the “Liquid Piping Systems Fundamentals” seminar will not be presented again in this seminar. It is advised that delegates review these topics as they are considered “assumed knowledge”.

     

    Seminar Objectives:

    At the completion of this seminar, each delegate should be able to:

    • Understand how pressure, temperature and velocity affect compressible fluid properties.
    • Appreciate the higher risks associated with compressible flow systems compared to liquid flow systems.
    • Perform pipe sizing calculations for the flow of fuel gas, steam, compressed air etc based on a number of popular industry methods.
    • Perform basic control valve sizing calculations and have a greater understanding of the difficulties associated with control valves for compressible flow.
    • Be better placed to select materials of construction for common gas piping systems.
    • Design/select/calculate gas piping ancillaries such as: relief and safety valves; flares and vents; dryers; condensate traps.
    • Be aware of the more common gas piping operational issues such as “double block and bleed”, valve leakage classes, determining system leakage, wear rates and hot tapping etc.
    • Be able to perform pressure drop calculations for gases in pipes, fittings and valves using common industry methods.
    • Have a greater understanding of hazardous area classifications and the flow of combustibles through pipe systems.
    • Appreciate how to better lay gas piping systems out so that operational safety is paramount.

     

    Training Seminar Materials:

    All delegates receive:

    • A Detailed Seminar Manual – Which provides a reference text of all of the material presented during the seminar. Note: This manual is written as a textbook which allows it to be more useful as a future design reference.
    • Certificate of Attendance – Which states the number of hours of training and serves as documentary proof of attendance.
