What does nitrogen purging mean?
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.
What is shielding gas arc welding?
shielded metal arc welding does not required any shielding gas
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.
How do you seal a copper flare joint?
A flare joint is used on gas fittings and uses a nut and flare fitting to make the connection. This is a dry fit with no joint compound. The copper is soft enough that it compresses with the nut and forms the seal.
What tools are required for a lp gas conversion from natural gas?
Usually kits are sold that have all the required tools for this. Generally the tools included in these kits are a gas hose, a jet wrench, valve limiters, and a hose wrench. Buying kits can sometimes be cheaper than buying all the individual parts if you do not have any of these tools already.
What is the need of Purging in boiler?
purging is a cleaning process which cleans explosive items in air,flue gas path if any.
What is purging means in oil tanker?
introduction of inert gas in inerted tank ...
Is their any neutral gas other than nitrogen for purging?
Yes, Helium is neutral (inert, noble) gas
How do you fix a gas tank seal leak?
To fix a gas tank seal leak you must drain the gas into an empty bucket and remove the tank. Then, cover the outlet holes with putty and re-install it.
What is nitrogen flushing?
Exactly waht it sounds like - flooding/flushing/purging something with nitrogen gas (often to exclude oxygen (air))
Why seal flush required in a pump?
Always glycol sealing is found in LPG or pupms which used under gas form in order to prevent leakage of light components to surrounding and preventing fires
What is used to hold gas?
a gas chamber or a air tight seal if you cant get your hands on a chamber
Will silicone seal a gasoline leak?
the gas will eat the silicone
What does code p0455 on a 2006 Saab 9-3 mean?
the code stands for a "Large Evap Leak" check your gas cap seal and change out the gas cap if the seal is bad, do not purchase aftermarket gas caps for Saabs.
What is the temperature required to liquefy a gas?
Depends which gas
What is gas needed for?
Oxygen is the gas that is required for respiration.
Check gas cap Saturn?
Gas Cap is not on tight, or the seal leaks and you need to replace the cap.
