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

Compressed gas providers like Wright Brothers often put forth a lot of effort to satisfy their Cincinnati 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 Cincinnati consumer. Throughout this, the gases face several different types of  gas equipment and methods of handling that will either lessen or protect its purity.

Gas handling systems can differ from being very 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 a component that should never be underestimated. Likewise, the employment of certain toxic gases can introduce safety hazards if they are not used with the proper equipment.As a result, Wright Brothers strives to ensure that we are always using the proper equipment and that our Cincinnati customers are too

The goal 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 correct regulator can preserve gas purity while simultaneously delivering it safely. Because of its value, there are several different elements to contemplate when selecting the right regulator for an operation.

The initial element to consider when choosing a regulator is the purity level that is needed 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 requires high-purity gas, then a high-purity regulator should be utilized rather than a general-purpose or other unsatisfactory regulator. At the very least, regulators that are utilized in delivery systems should be cleaned by the supplier to assure both cleanliness and safe utilization.

One more matter that needs to be taken into consideration when selecting the best 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, on the other hand is used for stainless steel, brass, and other materials. There are many reasons for which barstock bodies are preferred for high-purity applications. One reason is its small internal volume which leads to easier purging, thus enabling impurities and moisture to be removed. Additionally, barstock has a smoother internal surface which reduces the amount of contaminants that are retained inside. To conclude, 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 often in pressure regulators. In specific higher-purity employments or in circumstances where brass is incompatible with the gas being used, 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 usually compatible with brass and most other materials. 316 stainless steel is most commonly utilized in applications that require 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 requirements, stainless steel should be utilized. For gases that are highly corrosive, Monel or Hastelloy should be the materials that are used because they lead to more corrosion resistance.
