INSTRUCTOR:
Mark Peterson, P.E.
Purpose and Background
Design of pressure pipes for water systems and force mains requires careful selection of the appropriate material. Not all pipe materials are acceptable for all systems. This course will provide guidance on the materials commonly used for pressure systems including PVC, ductile iron, HDPE and steel. It will also cover evaluation of transients (water hammer) and design of appropriate joint restraints to resist thrust forces at fittings.
Benefits and Learning Outcomes
Upon completion of this course, you will be able to:
- Explain the advantages and disadvantage of the common material options for pressure pipes, including PVC, ductile iron, HDPE and steel
- Explain how pressure ratings are determined for the various materials
- Recognize the forces in pressure pipes and at bends and other fittings, including working pressure and transient (water hammer) forces
- Demonstrate how transients are calculated and modeled
- Explain how transients can be limited by design, operation and various devices
- Explain how thrust blocks and restrained joints resist the thrust forces
- Size thrust blocks and restrained joint lengths
Assessment of Learning Outcomes
Achievement of the learning outcomes will be assessed through class discussion a short post-test (true-false, multiple choice and fill in the blank questions).
Who Should Attend?
This course is for anyone involved in the design or review of systems where pressure pipes are used, including water systems and sanitary and storm sewer force mains.
This course is intended for design engineers, system managers and regulatory officials.
Outline

- Friction factors and nominal vs. actual diameters •
- Minimum and maximum cover for pipes
- Causes of transients
DAY 2
- Speed of transient wave and magnitude of pressures

- Devices for restraining various pipe options
How to Earn your CEUs/PDHs
This course is worth 1.4 CEU’s /14PDHs To receive your certificate of completion, you will need to complete a short on-line post-test and receive a passing score of 70% or higher within 30 days of the course.
How do I convert CEUs to PDHs?
1.0 CEU = 10 PDHs [Example: 0.1 CEU = 1 PDH]
