Course Description: Condensation induced water hammer is a major source
of industrial accidents and equipment downtime in steam piping systems. This
type of water hammer event occurs when steam, trapped by sub cooled condensate,
condenses back into water, which result in destructive pressure pulses within
the piping system. These pressure pulses can exceed 20 times the system design
pressure and may cause equipment damage, personal injury, and even death.
Students learn about this serious phenomenon and how it can be prevented, using
an effective combination of classroom instruction, videos, interactive group
exercises, and hands-on training to provide an optimum learning experience.
At the completion of this workshop,
the participants will be able to:
- Explain what a condensation induced water hammer is and how if forms in a
steam piping system.
- Understand the destructive force that can be released when a condensation
induced water hammer occurs.
- Apply the Safety Principle and Supporting Recommendations to help minimize the
potential for a water hammer to occur in your steam distribution systems.
- Locate potential hazard areas and implement appropriate corrective actions.
- Apply lessons learned from previous events to incorporate good operating
practices to help eliminate injuries and equipment damage.

Intended Audience: This course is intended for plant and facility
personnel that; design, maintain, repair, supervise, or operate steam plants and
distribution systems.
Evaluation Method: Subjective, depending on learner’s active
participation.
Supporting Text: Student work book and other reference material.
