John was grateful to have found the PDF handbook, and he realized that sometimes, it pays to be persistent and look for alternative sources of information. He also learned the importance of verifying the credibility of sources, especially when working with hazardous substances like ammonia.
The American Society of Mechanical Engineers code governing refrigeration piping and heat transfer components. : Proper sizing is vital to minimize pressure
Ammonia is highly corrosive to certain metals, like copper and brass. The handbook specifies approved materials, primarily focusing on carbon steel and specific stainless steel alloys. It details wall thickness requirements (Schedule 40 vs. Schedule 80) based on pipe diameter and pressure levels. 2. Sizing and Fluid Flow Calculations
