A large portion of the total cost of a typical oil & gas or chemical process plant is in the piping systems. A significant amount of operating cost (energy) and maintenance cost is also associated with the flow of fluids through the piping and its components. Understanding how fluid flows from one point to another is the foundation of process design and piping layout. The principles are not complex, but neither are they simple due to the interdependence of velocity, pipe diameter, length, fluid characteristics, pressure drop and friction.

This 4-hour course provides an overview of piping pressure drop calculation procedures and line sizing in a simplified manner. The course also provides an introduction to pipe wall thickness calculations for internal pressure.

This course is Part 3 of a 9-part series that covers the entire gamut of piping engineering in an easy-to-learn format. Each course in the series is stand-alone. Feel free to jump back and forth through the courses depending on your own knowledge and experience and your current needs. However, it is suggested that you complete the series in sequential order if you have limited knowledge of piping systems.

This course is intended for mechanical engineers, chemical engineers, piping engineers, control systems engineers, as well as civil, structural and electrical engineers who have a need or a desire to know more about piping components and systems. No prerequisite knowledge of the subject is required.
