Nitrogen purging means to inert the atmosphere of hydrocarbon vessels and lines. In other words to limit the oxygen contents so that it cannot react with the hydrocarbons and make some explosive mixtures.
Nitrogen Purging in Gas Well: (Oil & Gas Industry Terms, Well Activation)
Generally for gas well activation air compressors are used. Air compressor puts in oxygen into the Hydrocarbon system in the well, this results in explosive mixture (as hydrocarbon & oxygen can explode by a single spark). To reduce oxygen content in the well, Nitrogen is circulated at high pressure @ 80-100 Kg/cm2 from annulus (casing) and returns of gases are taken out from tubing of the well.
The Nitrogen purging job brings down chances of explosion / explosive mixtures.

∙ 11y agoThere isn't much to this. Prior to maintenance or start up, process lines are usually purged with nitrogen to remove any impurities within the system. So as you can see, all you do is inject nitrogen into process lines and you are effectively purging the system.

How is air being purged or recharged in telemotor of the steering gear?
Purge slowly into a pail or bucket in the telemotor hydraulic system purging valve until such a time pure hydraulic oil are coming out from the purging valve.
Why purging required for stainless welding?
During the welding of steels, oxidation occurs in the weld seam if oxygen reaches this area unhindered. This situation is even more acute with titanium, zirconium, molybdenum and other gas-reactive metals and alloys. The resulting oxidized surfaces are no longer corrosion-resistant, and further treatment is necessary. Removing oxidation by grinding also removes the metal's passive protection against corrosion. Other mechanical procedures, such as brushing, blasting and pickling remove the oxidation, which restores corrosion resistance. However, in some cases such as pipe welding, removing oxidation after welding is difficult or impossible to do. During pipe welding, oxides are usually located in areas that are almost impossible to access, such as in two 4-inch-diameter pipes that are each 10 feet long. Pickling will restore the corrosion resistance, but it is time-consuming and nearly impossible on a remote job site. Instead of removing oxidation, another solution is to prevent it from occurring in the first place. In essence, this is what purging tries to achieve. With purging, a gas is used to protect the weld seam until it has cooled to the point that oxidation no longer can occur. Usually, an inert gas, such as argon which is heavier than air, is used. Other purging gases such as nitrogen and nitrogen/hydrogen blends can also be used.

What is nitrogen gas used to make?
in the plumbing world nitrogen is used for purging the air, O2, out of medical gas lines or refrigeration lines for air conditioners. nitrogen is used because it does not burn like O2 thus leaving the inside of the pipe clean.

Why only nitrogen not other gases used in purging?
it is non flammable gas spark no explosion no fire. Added....Any of the intert gases are non flamable. Perhaps it's because Nitrogen is likely the cheaper and easier to produce than the other intert gases.
