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

Compressed gas distributors like Elite Air frequently put forth a lot of effort to satisfy their Riverside customer’s specific needs when it comes to accuracy, purity, and various other specifications. Most 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 Riverside consumer. Throughout this, the gases see several different types of  gas equipment and methods of handling that will either lessen or uphold 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 striking effect on the purity of the gas and is an item that should never be underestimated. Likewise, the employment of certain dangerous gases can present safety hazards if they are not utilized with the proper equipment.For this reason, Elite Air wants to ensure that we are always using the proper equipment and that our Riverside customers are as well

The function 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 proper regulator protect the gas’s purity while simultaneously delivering it with safety. Because of its value, there are many different concerns to take into consideration when deciding on the best regulator for an operation.

The initial thing to consider when choosing a regulator is the amount of purity that is required in the application. The three most common purity levels required are: general purpose, high-purity, and ultra-high purity.

For instance, if an application needs high-purity gas, then in response, a high-purity regulator should be utilized in place of a general-purpose or other inadequate regulator. At the very least, regulators that are employed in delivery systems should be kept clean by the supplier to assure both cleanliness and safe employment.

Another matter that should be considered 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 applied with only brass; barstock, however is used for stainless steel, brass, and other materials. There are many reasons for which barstock bodies are chosen 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. In addition, barstock has a smoother internal surface which lessens the number of contaminants that are retained inside. To conclude, 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 employed 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 with corrosive properties might need 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 used in applications that call for 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 enabling them to maintain noncorrosive gases with higher purity levels. For semi-corrosive or corrosive gases or gas mixtures and higher-purity requirements, 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.
