Nitrogen assist laser cutting leaves an oxide free finish on both mild and stainless steel. Unlike oxygen assist cutting nitrogen produces a receptive surface for subsequent painting or coating with no problems of rusting. Using nitrogen assist cutting is a more expensive process but there are as indicated significant benefits.

Shop air has oxygen and when exposed to petroleum based fluids or grease, can diesel (explode) under pressure. Pure oxygen is even more volatile. Other gases are expensive, corrosive or explosive. There are several grades of nitrogen gas available. For use in bladder accumulators, we recommend Commercial/Industrial Grade. This is the most common grade available and the most cost effective. It has been used with bladder accumulators for over 50 years. The average purity is 99.5%.

Models AR 48 & AR 62 use a nitrogen pre-charge. See the related document: AR 48 & 62 technical specifications.

Data from sites in the Southeastern U.S. show that after the initial year of establishment, nitrate losses under switchgrass and sweetgum decreased to less than 1 kg/ha compared with approximately 2-4 kg/ha from no-till corn. The highest N run-off was associated with rainfall occurring within a short period of time following fertilizer application in the spring - before the fertilizer had a chance to dissolve and move into the soil to be taken up by the plants.

We use Oxygen Free Nitrogen (OFN) for leak testing. It would be illegal to re-gas a system to use the refrigerant as a means of leak detection. The pure form of Nitrogen is a naturally occurring gas in the air that we breath and so is safe and legal to use. The Nitrogen is inserted into the system under high pressure thus simulating a system in operation and revealing any leaks in the system.

Yes, you can use any number of gases in your mixture. The instruction manual gives simple math to determine the linear "k-Factor" to apply to the reading if you purchased your meter for air and use it for a mixture of Nitrogen and Argon as an example. Feel free to click the Technical tab on the left to download the instruction manual that gives very good examples.

Nitrogen is the soil element that makes plants green. A few other things also aid in plant coloring: chlorophyll, phosphorous and iron. Other than water, nitrogen is the biggest component of plants. It can account for up to 5 percent of the total weight of annual plants. Plants lacking nitrogen have a pale color instead of a lush green color. Extreme care is very important when applying nitrogen. The correct amount is wonderful but too much is extremely harmful to plants.

Most lanterns are rated at 3451 BTU. They do not use a lot of gas. They simply keep a pretty flame glowing with soft light and use little more than a pilot light.

No. The member is responsible for ensuring the tank is at least one half full for the next user. If the gas level goes below 1/2, the member fills the tank and submits the receipt to The People's Car to have the cost deducted from their monthly bill. Return to top...

The nitrogen cycle, or cycling process, is the nitrification of your aquarium where beneficial bacteria form to consume the harmful types of nitrogen. When you begin a new tank, you will go through the nitrogen cycle. Fish waste and uneaten food break down into the first phase of nitrogen, ammonia. This is the most toxic to fish and gets dangerous at even low levels. For the good bacteria to begin to grow, there must be some level of ammonia.

In 2005, nearly 58 percent of all households (residential sector) used natural gas as their primary heating fuel accounting for about 22 percent of total natural gas consumed in the United States.

In 2006, the U.S. consumed nearly 22 trillion cubic feet (Tcf) of natural gas by the following seven natural gas end users:

The NPGA has developed a comprehensive maintenance program called GAS Check? (Gas Appliance System Check), in which trained technicians inspect propane systems and appliances in homes to ensure they are running safely and efficiently. The program also educates homeowners on the proper maintenance of propane appliances and how to handle propane safely.

The use of a vacuum assist system lowers the atmospheric pressure in the cooking chamber and therefore reduces the boiling temperature of the liquid. We typically recommend vacuum assist for certain types of solvents where the boiling point and flammable limit are within certain parameters. Our Specialists can identify if Vacuum Assist is needed in your process.

Yes. The omnidirectional has shown its value in this regard, especially in groups. Expanded states of consciousness have frequently been reported by users of Xenon-based unidirectional devices. Krypton containing devices have shown themselves to be valuable in enhancing psychic functioning of all kinds, which often aids in certain forms of meditation. I have used both north and south polarities.

Immediately following the gas release, Union Carbide Corporation began providing aid to the victims and established a process to resolve their claims. Among the many efforts Union Carbide took to address the situation were: Organizing a team of top medical experts to help identify the best treatment options and work with the local medical community; Offering a $2.2 million grant to establish a vocational-technical center in Bhopal to provide local jobs.

Absolutely and this is a good use for Brown's Gas. Our experiments show that even a tiny amount of Brown's Gas makes a noticeable improvement in petro fuel combustion. This is one basis for our HyZor Technology. Do you have a list of references for satisfied customers who would not mind discussing their experiences with the Brown's gas? A. We are working to put together such a list. We do not give out people's contact information without their express written permission.

Gas guns don't typically use CO2 cartridges found at local stores. They run on a special 'Green-Gas' that contains a silicone lubricant. The silicone lubricant helps the gun's durability and function.

A nitrogen atmosphere inside binoculars prevents internal fogging. Without any air inside the binocular, there is no humidity, and thus no condensation, even during a temperature change. And because the binoculars are airtight, they are also watertight and may be submerged.
