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

Compressed gas providers like Cee Kay Supply, Inc. usually put forth a lot of effort to satisfy their St. Louis 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 St. Louis consumer. Throughout this, the gases see several different types of  gas equipment and methods of handling that will either reduce or preserve its purity.

Gas handling systems can differ from being very detailed 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 an element that should never be underestimated. In addition, the employment of certain dangerous gases can produce safety hazards if they are not utilized with the proper equipment.because of this, Cee Kay Supply, Inc. strives to ensure that we are always using the proper equipment and that our St. Louis customers are also

The purpose of gas regulators in gas delivery systems is to lower the pressure from a high-pressure origin to a pressure level that is able to be used. The proper regulator can preserve gas purity while simultaneously delivering it harmlessly. Because of its importance, there are quite a few different concerns to contemplate when selecting the best regulator for a job.

The first thing to determine when selecting a regulator is the level of purity that is needed 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 calls for high-purity gas, then a high-purity regulator should be used rather than a general-purpose or other insufficient regulator. At the very least, regulators that are employed in delivery systems should be cleaned by the supplier to ensure both cleanliness and safe employment.

Another element that needs to be taken into consideration when choosing the proper regulator is the regulator’s body type. The bodies of regulators can be either produced from barstock or forged. Forging is utilized with only brass; barstock, contrarily is utilized for stainless steel, brass, and other materials. There are many reasons for which barstock bodies are favored for high-purity applications. One reason is its small internal volume which leads to easier purging, thus enabling impurities and moisture to be removed. In addition, barstock has a smoother internal surface which reduces the quantity of contaminants that are retained inside. Lastly, the grain structure of the metal is tighter in barstock, meaning it is less likely to absorb moisture and impurities.

In regards to materials of construction, brass is the material applied the most in pressure regulators. In specific higher-purity employments or in situations where brass is incompatible with the gas being utilized, other materials such as stainless steel are used. Gases that have corrosive properties sometimes call for 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 often employed in circumstances that need corrosion-resistant materials.

Forged brass bodies are most often employed with the lowest-purity gas, and in the lowest-cost regulators. Brass barstock bodies, however, have smoother internal finishes and smaller internal volumes giving them the ability 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.
