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

Compressed gas suppliers like Fresno Oxygen & Welding Supplies/Barnes Welding Supply typically put forth significant effort to fulfill their Fresno customer’s specific needs when it comes to accuracy, purity, and various other specifications. The majority of these specialty gases are shipped in traditional high-pressure cylinders, and others are shipped in bulk, smaller containers, or dewars. Regardless of the delivery method, these gases will eventually face handling, distribution, and regulation by the Fresno consumer. Throughout this, the gases face several different types of  gas equipment and methods of handling that will either lessen or preserve its purity.

Gas handling systems can vary from being very complicated 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 produce safety hazards if they are not utilized with the proper equipment.For this reason, Fresno Oxygen & Welding Supplies/Barnes Welding Supply strives to ensure that we are always using the right equipment and that our Fresno customers are too

The function of gas regulators in gas delivery systems is to lower 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 with safety. Because of its importance, there are several different matters to take into consideration when deciding on the best regulator for an operation.

The primary element to take into consideration when selecting a regulator is the level of purity that is needed 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 needs 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 kept clean by the provider to guarantee both cleanliness and safe employment.

An additional thing that requires 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 employed with only brass; barstock, contrarily is employed for stainless steel, brass, and various other materials. There are many reasons for which barstock bodies are preferred for high-purity applications. One reason is its small internal volume which makes it less difficult to purge, thus enabling impurities and moisture to be removed. Additionally, barstock has a smoother internal surface which lowers the number of contaminants that are retained inside. Lastly, the grain structure of the metal is tighter in barstock, meaning it does not absorb as many impurities and moisture.

In regards to materials of construction, brass is the material utilized most frequently in pressure regulators. In some higher-purity applications or in cases where brass is incompatible with the gas being utilized, other materials such as stainless steel are used. Gases containing corrosive properties might need 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 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, however, 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 mixtures and higher-purity requirements, stainless steel should be employed. For gases that are highly corrosive, Monel or Hastelloy should be the materials employed as they enable more corrosion resistance.
