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

Compressed gas suppliers like Toll Company often put forth a large amount of effort to answer to their Minneapolis 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 Minneapolis 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 vary from being quite complex 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 element that should never be underestimated. Additionally, the employment of certain hazardous gases can present safety hazards if they are not utilized with the proper equipment.For this reason, Toll Company wants to ensure that we are always using the best equipment and that our Minneapolis customers are as well

The function of gas regulators in gas delivery systems is to reduce the pressure from a high-pressure origin to a pressure level that is sufficient for use. The correct regulator protect the gas’s purity while simultaneously delivering it harmlessly. Because of its value, there are a lot of different elements to take into consideration when deciding on the right regulator for a job.

The primary part to evaluate when selecting a regulator is the purity level that is called for 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 in response, a high-purity regulator should be utilized rather than a general-purpose or other insufficient regulator. At the very least, regulators that are applied in delivery systems should be kept clean by the supplier to guarantee both cleanliness and safe utilization.

Another concern 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 applied with only brass; barstock, however is used for stainless steel, brass, and additional 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. In addition, barstock has a smoother internal surface which lessens the amount 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 utilized most frequently in pressure regulators. In certain higher-purity operations or in situations where brass is incompatible with the gas being utilized, 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 operations that need 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 allowing them to maintain noncorrosive gases with higher purity levels. For semi-corrosive or corrosive gases or gas mixes and higher-purity requirements, stainless steel should be utilized. For gases that are highly corrosive, Monel or Hastelloy should be the materials employed since they allow for more corrosion resistance.
