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

Compressed gas suppliers like A-OX Welding Supply frequently put forth a lot of effort to fulfill their Sioux Falls 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 way they are delivered, these gases will eventually face handling, distribution, and regulation by the Sioux Falls 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 differ from being quite 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 a component that should never be underestimated. In addition, the employment of certain toxic gases can introduce safety hazards if they are not utilized with the proper equipment.As a result, A-OX Welding Supply wants to ensure that we are always using the best equipment and that our Sioux Falls customers are as well

The goal of gas regulators in gas delivery systems is to reduce the pressure from a high-pressure origin to a pressure level that is suitable for use. The right regulator can preserve gas purity while simultaneously delivering it safely. Because of its value, there are a lot of different matters to contemplate when selecting the correct regulator for a job.

The primary thing to determine when deciding on the best regulator is the purity level that is required in the application. There are three categories under which these requirements usually fall: general purpose, high-purity, and ultra-high purity.

As an example, if an application requires high-purity gas, then in response, a high-purity regulator should be utilized instead of a general-purpose or other inadequate regulator. At the very least, regulators that are utilized in delivery systems should be cleaned by the distributor to guarantee both cleanliness and safe application.

An additional thing that requires 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 applied 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 decreases 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 used the most in pressure regulators. In specific higher-purity operations or in situations where brass is incompatible with the gas being utilized, other materials such as stainless steel are used. Gases with corrosive properties may require 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 often used in circumstances that need corrosion-resistant materials.

Forged brass bodies are most commonly utilized 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 blends and higher-purity requirements, stainless steel should be used. For gases that are highly corrosive, Monel or Hastelloy should be the materials that are used because they lead to more corrosion resistance.
