Technical parameters

Nitrogen (N2) constitutes the main part of the earth’s atmosphere, accounting for 78.08% of the total. It is a colorless, odorless, tasteless, non-toxic and almost completely inert gas. Nitrogen is non-flammable and is considered a suffocating gas (that is, breathing pure nitrogen will deprive the human body of oxygen). Nitrogen is chemically inactive. It can react with hydrogen to form ammonia under high temperature, high pressure and catalyst conditions; it can combine with oxygen to form nitric oxide under discharge conditions. Nitrogen is often referred to as an inert gas. It is used in certain inert atmospheres for metal treatment and in bulbs to prevent arcing, but it is not chemically inert. It is an essential element in the life of plants and animals, and is a component of many useful compounds. Nitrogen combines with many metals to form hard nitrides, which can be used as wear-resistant metals. A small amount of nitrogen in steel will inhibit grain growth at high temperatures and will also increase the strength of certain steels. It can also be used to produce hard surfaces on steel. Nitrogen can be used to make ammonia, nitric acid, nitrate, cyanide, etc.; in the manufacture of explosives; filling high-temperature thermometers, incandescent bulbs; forming inert materials to preserve materials, used in drying boxes or glove bags. Liquid nitrogen during food freezing; used as a coolant in the laboratory. Nitrogen should be stored upright in a well-ventilated, safe and weather-free place, and the storage temperature should not be higher than 52°C. There should be no flammable materials in the storage area and keep away from frequent entry and exit places and emergency exits, and no salt or other corrosive materials exist. For unused gas cylinders, the valve cap and output valve should be well sealed, and the empty cylinders should be stored separately from the full cylinders. Avoid excessive storage and long storage time, and maintain good storage records.
