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

Compressed gas distributors like Noble Gas Solutions usually put forth a large amount of effort to answer to their Albany customer’s specific needs when it comes to accuracy, purity, and various other specifications. The majority of these specialty gases are shipped in traditional high-pressure cylinders, and others are shipped in bulk, smaller containers, or dewars. Regardless of the way they are delivered, these gases will eventually face handling, distribution, and regulation by the Albany consumer. Throughout this, the gases see several different types of  gas equipment and methods of handling that will either decrease or protect its purity.

Gas handling systems can differ from being very complicated to quite simplistic. But regardless of its configuration, the gas delivery system can have a notable effect on the purity of the gas and is a component that should never be underestimated. Additionally, the employment of certain dangerous gases can produce safety hazards if they are not used with the proper equipment.For this reason, Noble Gas Solutions wants to ensure that we are always using the best equipment and that our Albany customers are too

The purpose of gas regulators in gas delivery systems is to decrease the pressure from a high-pressure origin to a pressure level that is able to be used. The correct regulator can preserve gas purity while simultaneously delivering it with safety. Because of its value, there are many different elements to take into consideration when choosing the proper regulator for an application.

The primary element to determine when selecting a regulator is the purity level that is called for in the application. The three purity levels found in most applications are: general purpose, high-purity, and ultra-high purity.

For example, if an application requires high-purity gas, then a high-purity regulator should be employed instead of a general-purpose or other unsatisfactory regulator. At the very least, regulators that are utilized in delivery systems should be kept clean by the distributor to guarantee both cleanliness and safe application.

Another matter that needs to be taken into consideration when deciding on the correct regulator is the regulator’s body type. The bodies of regulators can be either made from barstock or forged. Forging is employed with only brass; barstock, however is utilized for stainless steel, brass, and various other materials. There are several reasons for which barstock bodies are preferred for high-purity applications. One reason is its small internal volume which makes it less difficult to purge, thus facilitating the elimination of impurities and moisture. Likewise, barstock has a smoother internal surface which lowers the amount of contaminants that are retained inside. Lastly, the grain structure of the metal is tighter in barstock, meaning it absorbs less moisture and impurities.

In regards to materials of construction, brass is the material used most frequently in pressure regulators. In some higher-purity employments or in cases where brass is incompatible with the gas being employed, other materials such as stainless steel are used. Gases that have corrosive properties may require corrosion-resistant materials for all wetted parts, but flammables and inert gases are typically 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 often employed 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 needs, stainless steel should be employed. For gases that are highly corrosive, Monel or Hastelloy should be the materials employed because they enable more corrosion resistance.
