Abstract: Instant answers to your toughest questions on piping components and systems! It's impossible to know all the answers when piping questions are on the table - the field is just too broad. That's why even the most experienced engineers turn to the Piping Handbook, edited by Mohinder L. Nayyar, with contributions. Relief valves are an important safety feature in industrial ammonia refrigeration systems. They protect the system from over pressurization and possible explosion. The discharge piping is also an important part of the relief valve system. It must be sized properly so the relief valve capacity is not affected, and it must route the. IIAR Ammonia Pipe Markers.

Introduction: Ammonia (azane(1) or R-717) was among the early refrigerants, first used in 1850 in France(2). It was then utilized in the US in the 1860s for artificial ice production and then the first ammonia refrigeration machines were patented in the 1870s. Ammonia is one of the early chemicals to secure a lasting role as a. sizing of valves, relief valves pipes and vessels are discussed.

In the past a lot of scientist, engineers and other men have devoted their interest and energy to freezing problems, heat transfer and pressure drops in ducting systems. We have challenged faith to find our way in a huge amount of information to select the proper information needed to design our own refrigeration plant. Ammonia has been and continues to be the predominant refrigerant used in the cold storage and food processing industry. However, as a result of industrial accidents, the potential as a terrorist target, drug trafficking, and growing local concerns, its use has come under increased scrutiny over the past.
