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

Compressed gas suppliers like Sidney Lee Medical & Scientific Gases typically put forth serious effort to fulfill their Atlanta, GA 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 Atlanta, GA consumer. Throughout this, the gases face 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 extremely complicated 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 a component that should never be underestimated. In addition, the employment of certain dangerous gases can produce safety hazards if they are not used with the proper equipment.As a result, Sidney Lee Medical & Scientific Gases wants to ensure that we are always using the correct equipment and that our Atlanta, GA 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 safely. Because of its value, there are several different concerns to consider when choosing the correct regulator for a job.

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

For instance, if an application requires high-purity gas, then a high-purity regulator should be employed rather than a general-purpose or other unsatisfactory regulator. At the very least, regulators that are applied in delivery systems should be cleaned by the distributor to guarantee both cleanliness and safe utilization.

One more thing 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 generated from barstock or forged. Forging is used with only brass; barstock, however is used for stainless steel, brass, and various 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 allowing the removal of moisture and impurities. Likewise, barstock has a smoother internal surface which lessens the quantity of contaminants that are retained inside. Finally, 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 certain higher-purity operations or in situations where brass is incompatible with the gas being employed, other materials such as stainless steel are used. Gases containing 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 circumstances that require corrosion-resistant materials.

Forged brass bodies are most frequently used with the lowest-purity gas, and in the lowest-cost regulators. Brass barstock bodies, however, 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 needs, stainless steel should be used. For gases that are highly corrosive, Monel or Hastelloy should be the materials employed because they allow for more corrosion resistance.
