How the Gas Pressure Regulator Helps You Get the Most Out of Compressed Gases

Compressed gas providers like Arc3 Gases frequently put forth a large amount of effort to fulfill their Richmond, Virginia customer’s specific needs when it comes to accuracy, purity, and various other specifications. Many of these specialty gases are shipped in traditional high-pressure cylinders, and others are shipped in bulk, smaller containers, or dewars. Regardless of the shipping method, these gases will eventually face handling, distribution, and regulation by the Richmond, Virginia consumer. Throughout this, the gases come into contact with several different types of  gas equipment and methods of handling that will either reduce or preserve its purity.

Gas handling systems can vary from being quite complex to quite simplistic. But regardless of its configuration, the gas delivery system can have a striking effect on the purity of the gas and is an item that should never be underestimated. In addition, the employment of certain hazardous gases can produce safety hazards if they are not utilized with the proper equipment.As a result, Arc3 Gases strives to ensure that we are always using the proper equipment and that our Richmond, Virginia customers are also

The goal of gas regulators in gas delivery systems is to lessen the pressure from a high-pressure origin to a pressure level that is suitable for use. The correct regulator protect the gas’s purity while simultaneously delivering it without harm. Because of its significance, there are several different matters to take into consideration when choosing the correct regulator for an operation.

The first thing to evaluate when deciding on the best regulator is the purity level that is called for in the application. The three most common purity levels required are: general purpose, high-purity, and ultra-high purity.

For instance, if an application calls for high-purity gas, then as a result, a high-purity regulator should be utilized in place of a general-purpose or other insufficient regulator. At the very least, regulators that are used in delivery systems should be cleaned by the distributor to assure both cleanliness and safe employment.

Another matter that needs to be taken into consideration when selecting the best regulator is the regulator’s body type. The bodies of regulators can be either generated from barstock or forged. Forging is used with only brass; barstock, contrarily is utilized for stainless steel, brass, and additional materials. There are several reasons for which barstock bodies are preferred for high-purity applications. One reason is its small internal volume which leads to easier purging, thus enabling impurities and moisture to be removed. Likewise, barstock has a smoother internal surface which lessens the amount of contaminants that are retained inside. Finally, the grain structure of the metal is tighter in barstock, meaning it does not absorb as many impurities and moisture.

In regards to materials of construction, brass is the material utilized the most in pressure regulators. In some higher-purity applications or in circumstances where brass is incompatible with the gas being utilized, other materials such as stainless steel are used. Gases with corrosive properties may require corrosion-resistant materials for all wetted parts, but flammables and inert gases are generally compatible with brass and most other materials. 316 stainless steel is most commonly used in applications that require corrosion-resistant materials.

Forged brass bodies are most frequently used with the lowest-purity gas, and in the lowest-cost regulators. Brass barstock bodies, contrarily, have smoother internal finishes and smaller internal volumes allowing them to maintain noncorrosive gases with higher purity levels. For semi-corrosive or corrosive gases or gas blends and higher-purity demands, stainless steel should be employed. For gases that are highly corrosive, Monel or Hastelloy should be the materials utilized because they lead to more corrosion resistance.
