Do You Know Your Valves?

Cryogenic Gases has a great selection of valves. These are the types we carry and what they are best used for.

Check Valve
Check valves prevent the return flow of gas, thus keeping foreign substances out of lines, regulators and cylinders located upstream of the valve.
High Purity Diaphragm
High Purity Diaphragm Packless Valves are recommended whenever the diffusion of atmospheric gases and moisture into a gas system is undesirable. They are a must in all ultrahigh purity gas transfer systems, particularly those used for gas chromatography carrier gases, samples and calibration standards.
Manual Control Valves
Manual controls are designed for direct connection to a compressed gas cylinder valve outlet. They provide a simple means of transferring the contents of a cylinder to another system or vessel. They DO NOT control pressure and should never be used without an operator in attendance at all times.
Minature Needle Valve
These valves are used in a wide variety of industrial and laboratory applications. They offer excellent flow control and both the brass and stainless steel models have Teflon® packing.
Pressure Relief Valve
These easily field adjustable relief valves provide for the protection of equipment components installed in systems where they may be exposed to over pressurization due to the failure of another component or an operator error.

Why You Need An Electronic Cylinder Scale

Have you ever experienced a serious disruption in your operations or a loss of product?

Didn't know what to do or how to prevent it from happening again?

An electronic cylinder scale could be just the solution for you!

The pressure of a liquefied gas remains constant as material is withdrawn as long as a liquid phase remains in the cylinder. When the liquid phase is exhausted the pressure drops very quickly and the cylinder empties without warning. This phenomenon renders a cylinder pressure gauge virtually useless. A similar situation arises when using cryogenic containers of liquid nitrogen, oxygen, and argon. The only way to monitor the contents of a cylinder of liquefi ed gas or a cryogenic container is by weight.

Electronic scales are designed to give a positive indication of the amount of product remaining in the cylinder as material is being withdrawn. These units allow the user to electronically subtract the tare weight of the cylinder so that only the net contents can be read directly. The built-in alarm can be set for any weight value from 0- 100% of the scale's capacity.

With the red LED visual alarm and audible alarm you will never have to guess when your alarm set point is reached.

For easy access, a ramp is available for each model so that cylinders can easily be rolled on and of the scale platform without lifting.

More About Methane

What is Methane?

It is a colorless, odorless, and tasteless gas at normal temperatures and pressures, and has many beneficial uses.

It is highly flammable, and in the proper mixture percentages mixed within air, it is HIGHLY EXPLOSIVE. Due to this aspect, an "odorant" is added so that it be detected by smell if it leaks.

Methane is relatively "pure" and is more commonly known as "Natural Gas."

What is Methane used for?

Among other things, Methane can be use for heating and cooling, cooking, electrical power and even as fuel for vehicles. Methane is also most commonly used as for the creation of many different products, such as plastics, for the manufacture of plastic bags and many different types of containers.

Cryogenic Gases can supply your Methane needs.

Whatever your needs, we can help find a solution that works for you. So, please contact us today.

Cryobiology

You may not realize it, but cryogenics is utilized in many different areas.

Cryobiology, or cryogenics, involves the study of the effects of freezing and low temperatures on living as well as non-living things. This can include humans, plants, animals and even machinery.

For instance, in hospitals cryobiology makes use of the latest techniques for a growing number of surgeries and treatments. Some of these are as simple as freezing off a lesion, or growth.

Cryogenics also makes possible preservation of embryos.

Neuropreservation is also possible through the use of cryobiology. Though it may seem a little extreme, through this process of freezing someone after death, a large number of studies and research has been made possible.

So, as you can see, cryogenics plays a huge part in not just the area of welding, but also the medical field and may others as well.

Whatever your needs may be, let Cryogenic Gas help you find the right gases and/or equipment for you.

Hydrogen: Fuel of the Future?

Is hydrogen the answer to a means of alternative fuel? It seems likely that it will be years before we have a true answer, but it certainly is worth investigating.

Unfortunately, right now there is quite a high cost of building hydrogen fuel-cell vehicles. In order for the average person to be able to afford a vehicle of this type, automakers would need to reduce costs drastically.

Another issue is the fact that gasoline is where the money is and will be for the forseeable future. There are not enough hydrogen refueling stations at this point.

The benefits, however, are great. The only by-product of running a hydrogen-powered fuel cell is oxygen and a trickle of water, neither of which will cause any harm to human health or the environment. In and of itself, that right there makes this alternative a hot commodity. Only the future will tell how things will play out.

Why Use A Gas Purifier?

Typical contaminants, such as moisture, oxygen, and hydrocarbons wreak havoc with GC (Gas Chromatography) columns and detectors.

A clean gas stream helps guarantee the quality of your GC analysis and the reliability of your results. Gas purifiers act as an insurance policy, protecting your instrumentation and analytical columns from these contaminants.

There are a variety of gas purifiers available. Some remove a specific contaminant while others remove multiple contaminants from your gas stream. There are several factors you need to consider when selecting purifiers for your application. These include contaminants potentially present in your gas stream, gas purity levels required, flow and pressure limitations, space availability, and desired convenience when replacing spent traps.

Moisture, hydrocarbon, and oxygen traps are the most commonly used purifiers for GC applications.

Purifier capacity indicates the amount of contaminant a trap is capable of removing before it reaches its point of saturation. It is dependent on both the adsorbent’s capabilities and purifier’s volume. You need to consider the amount of impurities in your gas stream and the volume of gas you need to purify. If you are purifying a large volume of gas or a less pure gas, you should select a high capacity trap with a large volume adsorbent bed that will trap and retain more contaminants.

Purifier efficiency is the most important purifier characteristic as it indicates how effective the adsorbent is at removing the desired contaminant from your gas stream.

For help finding the proper gas purifier for you or for more information about out cryogenic gas equipment and supplies, please contact us for more information.

A Few Words On Pressure Regulators

If you’re new to the world of welding and perhaps are unsure of just exactly what a pressure regulator does and would like to know more about them, the following is an overview.

A pressure regulator is a valve that automatically cuts off the flow of a liquid or gas at a certain pressure. Regulators are used to allow high-pressure fluid supply lines or tanks to be reduced to safe and/or usable pressures for various applications.

A pressure regulator's primary function is to match the flow of gas through the regulator to the demand for gas placed upon the system. If the load flow decreases, then the regulator flow must decrease also. If the load flow increases, then the regulator flow must increase in order to keep the controlled pressure from decreasing due to a shortage of gas in the pressure system.

What are they used for?

Oxy-fuel welding and cutting processes require gases at specific pressures, and regulators will generally be used to reduce the high pressures of storage cylinders to those usable for cutting and welding.

Propane and LP Gas applications require the use of a regulator. Because pressures in propane tanks can fluctuate significantly, regulators must be present to deliver a steady flow pressure to downstream appliances.

Pressure regulators are also used with air tanks used for breathing during SCUBA diving. The tank may contain pressures well in excess of 2000 PSI, which could cause a fatal injury to a person breathing it directly. The regulator allows for only a sustained flow of air at a breathable rate.

All of our gas handing equipment includes high purity single stage and dual stage pressure regulators. For more information, please contact us.
