Ammonia Pipe Marking

Although ammonia is such a widely used compound across various industries, there are a range of safety hazards which must be addressed for safe handling. It can be used for purposes such as food processing or chemical manufacturing, requiring correct pipe marking to ensure regulations are met and risks are minimized. In this article, we … Read more

A base is any molecule that accepts a proton, while an acid is any molecule that releases a proton. For this reason, ammonia is considered basic because its nitrogen atom has an electron pair that readily accepts a proton. However, ammonia is classified as a weak base which is a chemical compound that doesn’t completely … Read more

“Is ammonia safe to use” may sound like a trick question, as you might have seen from our other Q&As on ammonia that it can be dangerous, yet has various uses for fertilizer and refrigeration. There are several pros and cons to using ammonia that make it hard to pin down the exact right answer. … Read more

Pipe marking can be difficult, especially when the labels must be correct, since handling hazardous materials is no laughing matter. Ammonia labels fall high on the list due to ammonia’s dangerous nature. There are several different colors that must accompany an ammonia label. These colors correlate with the five different parts of an ammonia label … Read more

Any sort of pipe that contains ammonia must be appropriately labeled to assure the awareness of each employee on the contents of the pipe, especially when it contains something as corrosive as ammonia. The regulations on size and color are listed in the ANSI/ASME A 13.1 2015 ruling with the IIAR’s bulletin #114 guidelines to … Read more

The IIAR is an acronym for the International Institute of Ammonia Refrigeration. The institute oversees the standards on labeling industrial refrigeration equipment for all those who interact with the refrigeration system and its necessary components. The IIAR does this through education and advocacy as they are striving to be the main provider on performance standards … Read more

To answer this question, we must first look into why ammonia is used in the first place. Back when refrigeration was needing more synthetic refrigerants in the 20th century, chlorofluorocarbons were more commonplace or refrigerants like Freon-12. These synthetic refrigerants were used until it was found that they were dangerous to the environment, that’s when … Read more

To start off, refrigeration systems essentially move heat out of one area to another leaving an area cooler than it was before. This process is the basic transfer of energy by moving it from one place to the next with the use of vapor compression. Think of this process as similar to sweating, it keeps … Read more

This manufactured chemical is made through the Haber-Bosch process that fixes hydrogen and nitrogen together by using a highly pressurized and heated catalyst plus an industrial reactor to make the chemical compound known as NH3. Keeping this manufactured chemical in a stable condition where it can be handled is imperative as it is very volatile … Read more

While NH3 is dangerous, anhydrous ammonia also has countless uses relating to the medicinal field, functions as a cleaning agent when diluted, is commonly used as a fertilizer, and in some cases is stolen to illegally produce methamphetamine. Most anhydrous ammonia is produced for the agricultural community. 175 million tons of anhydrous ammonia was produced … Read more
