Piping Handbook Chapter 1 Certificate Course
Self-Paced Online Course
Learn the fundamentals of ammonia pipe sizing using pressure drop principles, velocity, mass flow, and practical application examples from Chapter 1 of the Ammonia Piping Handbook.
Course Description
This self-paced certificate course introduces the fundamentals of closed-circuit ammonia refrigeration system pipe sizing using pressure drop principles. Participants will learn how line sizing is influenced by temperature change, pressure drop, velocity, mass flow, and nomographs.
The course includes eight modules covering line sizing for:
- discharge lines
- liquid lines
- suction lines
- gas defrost lines
- headers
- pump recirculated liquid lines
Additional topics include:
- single-phase flow
- two-phase flow
- flow reversal
- equivalent length
- valve considerations
After participating in the Module 1 activity, learners will be able to:
