Liquid ammonia is a colorless liquid with a strong irritating odor, so safety should be taken very seriously during transportation. In the transportation of liquid ammonia, a liquid ammonia crane tube is used, and the setting requirements of the liquid ammonia crane tube also need to meet the conditions for the transportation of ammonia.

Liquid ammonia crane tubes are generally used in chemical related factories and enterprises. Liquid ammonia is mainly used for the production of nitric acid, urea, and other chemical fertilizers, and can also be used as a raw material for pharmaceuticals and pesticides. It can also be used in factories and enterprises related to semiconductor and metallurgical industries. Heating liquid ammonia to 800-850 ℃, under the action of nickel based catalysts, the ammonia is decomposed to obtain a hydrogen nitrogen mixture gas containing 75% H2 and 25% N2. The gas obtained by this method is a good protective gas and can be widely used in factories and enterprises related to large-scale refrigeration equipment in the semiconductor and metallurgical industries. Liquid ammonia is widely used as a refrigerant in large-scale refrigeration equipment.
