Industrial High Purity 99.999% Nitrogen 
Nitrogen gas is widely used in the industry of Chemicals, Pharmaceuticals, Food and Beverage, Glass, Cement and Lime,Healthcare, Laboratories & analysis, Electronics, Electronics, Automotive & transportation and Other industries.Nitrogen gas is manufactured by air separation.The purity is 99.999%.After the post-processing, manufacturing 99.9999% purity N2.
Typical Technical Data:
Nitrogen gas has a variety of applications, including serving as an inert replacement for air where oxidation is undesirable.
-1).As a modified atmosphere, pure or mixed with carbon dioxide, to preserve the freshness of packaged or bulk foods (by delaying rancidity and other forms of oxidative damage). Pure nitrogen as food additive is labelled in the European Union with the E number E941.
-2).In incandescent light bulbs as an inexpensive alternative to argon.
-3).In photolithography in deep ultraviolet, to avoid a strong oxygen absorption.
-4).Dried and pressurized, as a dielectric gas for high-voltage equipment.
-5).The manufacturing of stainless steel.
-6).Used in some aircraft fuel systems to reduce fire hazard.
-7).On top of liquid explosives as a safety measure.
-8).Filling automotive and aircraft tires due to its inertness[citation needed] and lack of moisture or oxidative qualities, as opposed to air.

Our Aluminum alloy gas cylinders can be refilled with rare, high pure, calibration and special gases. They are made of superior quality aluminum alloy and manufactured through the procedures of punching, drawing, heat treatment, CNC flow forming spinning, anodic oxidation treatment to the inner surface, etc. It is used to be filled and refilled with various kinds of gases, such as rare gases, high purity gases, standard gases, special gases, with a wide range of applications in the chemical industry, electronic industry, medical treatment, gas and coal mining fields, which is the ideal substitute for the steel cylinder. We also have the ability to design and produce the seamless aluminum alloy cylinders with special specifications and technical requirements.

BTW, high pressure seamless aluminium air cylinders are adopted to fill various compressed gas, including industrial specialty gases, pure gases, gas mixtures and air. (Such as Argon, Chlorine, Ethane, Helium, Hydrogen, Neon, Nitrogen, Oxygen, Nitrogen monoxide, Nitrous oxide and etc).*About Us:
