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

Compressed gas providers like Weldstar Specialty Gases usually put forth significant effort to fulfill their Northern Illinois 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 Northern Illinois consumer. Throughout this, the gases face several different types of  gas equipment and methods of handling that will either reduce or uphold its purity.

Gas handling systems can vary from being very detailed 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 item that should never be underestimated. Additionally, the employment of certain hazardous gases can introduce safety hazards if they are not employed with the proper equipment.As a result, Weldstar Specialty Gases wants to ensure that we are always using the correct equipment and that our Northern Illinois customers are too

The function of gas regulators in gas delivery systems is to lessen the pressure from a high-pressure origin to a pressure level that is suitable for use. The proper regulator can preserve gas purity while simultaneously delivering it harmlessly. Because of its importance, there are several different matters to take into consideration when selecting the right regulator for a job.

The primary part to evaluate when deciding on the best regulator is the purity level that is called for in the application. The three most common purity levels required are: general purpose, high-purity, and ultra-high purity.

For instance, if an application requires high-purity gas, then as a result, a high-purity regulator should be used 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 ensure both cleanliness and safe utilization.

Another element that requires consideration when choosing the proper regulator is the regulator’s body type. The bodies of regulators can be either produced from barstock or forged. Forging is applied with only brass; barstock, contrarily is used for stainless steel, brass, and additional 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 leads to easier purging, thus facilitating the elimination of impurities and moisture. In addition, barstock has a smoother internal surface which lessens the amount of contaminants that are retained inside. Finally, 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 cases where brass is incompatible with the gas being utilized, other materials such as stainless steel are used. Gases that have 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 utilized in applications 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, 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 needs, stainless steel should be used. For gases that are highly corrosive, Monel or Hastelloy should be the materials employed since they allow for more corrosion resistance.
