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

Compressed gas suppliers like WestAir Specialty Gases and Equipment typically put forth serious effort to satisfy their Southern California 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 shipping method, these gases will eventually face handling, distribution, and regulation by the Southern California consumer. Throughout this, the gases see several different types of  gas equipment and methods of handling that will either lower or uphold its purity.

Gas handling systems can range from being very detailed to quite simplistic. But regardless of its configuration, the gas delivery system can have a significant effect on the purity of the gas and is an element that should never be underestimated. Likewise, the employment of certain hazardous gases can introduce safety hazards if they are not used with the proper equipment.As a result, WestAir Specialty Gases and Equipment strives to ensure that we are always using the correct equipment and that our Southern California customers are also

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 sufficient for use. The proper regulator protect the gas’s purity while simultaneously delivering it safely. Because of its value, there are many different concerns to contemplate when deciding on the correct regulator for a job.

The primary matter to determine when choosing a regulator is the purity level that is called for in the application. There are three categories under which these requirements usually fall: general purpose, high-purity, and ultra-high purity.

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

An additional element that requires 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 used with only brass; barstock, contrarily is employed for stainless steel, brass, and other materials. There are quite a few 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. Additionally, barstock has a smoother internal surface which decreases the number 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 the most in pressure regulators. In certain higher-purity operations or in cases where brass is incompatible with the gas being employed, other materials such as stainless steel are used. Gases containing 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 used 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, on the other hand, 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 mixtures and higher-purity demands, stainless steel should be utilized. For gases that are highly corrosive, Monel or Hastelloy should be the materials utilized since they lead to more corrosion resistance.
