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

Compressed gas suppliers like American Welding & Gas, Inc. usually put forth a large amount of effort to answer to their Indianapolis 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 method of shipping, these gases will eventually face handling, distribution, and regulation by the Indianapolis consumer. Throughout this, the gases come into contact with several different types of  gas equipment and methods of handling that will either decrease or preserve its purity.

Gas handling systems can vary from being extremely 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. Likewise, the employment of certain toxic gases can produce safety hazards if they are not utilized with the proper equipment.As a result, American Welding & Gas, Inc. works hard to ensure that we are always using the proper equipment and that our Indianapolis customers are as well

The function 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 protect the gas’s purity while simultaneously delivering it harmlessly. Because of its importance, there are several different matters to take into consideration when selecting the correct regulator for an operation.

The initial thing to take into consideration when deciding on the best regulator is the level of purity that is required in the application. The three purity levels found in most applications are: general purpose, high-purity, and ultra-high purity.

As an example, if an application needs high-purity gas, then a high-purity regulator should be used instead of a general-purpose or other insufficient regulator. At the very least, regulators that are employed in delivery systems should be washed by the provider to ensure both cleanliness and safe application.

Another element that should be considered 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, however is used for stainless steel, brass, and other materials. There are several reasons for which barstock bodies are favored for high-purity applications. One reason is its small internal volume which makes it easier to purge, thus enabling impurities and moisture to be removed. Likewise, barstock has a smoother internal surface which lowers 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 used most often in pressure regulators. In specific higher-purity employments or in circumstances where brass is incompatible with the gas being employed, other materials such as stainless steel are used. Gases with corrosive properties might need 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 often employed in circumstances that call for 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 enabling them to maintain noncorrosive gases with higher purity levels. For semi-corrosive or corrosive gases or gas mixes and higher-purity demands, stainless steel should be used. For gases that are highly corrosive, Monel or Hastelloy should be the materials employed because they lead to more corrosion resistance.
