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

Compressed gas producers like Coastal Welding Supply often put forth significant effort to fulfill their Beaumont 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 way they are delivered, these gases will eventually face handling, distribution, and regulation by the Beaumont consumer. Throughout this, the gases face several different types of  gas equipment and methods of handling that will either reduce or preserve its purity.

Gas handling systems can differ from being very complicated 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. Likewise, the employment of certain dangerous gases can present safety hazards if they are not employed with the proper equipment.because of this, Coastal Welding Supply works hard to ensure that we are always using the best equipment and that our Beaumont customers are also

The function 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 protect the gas’s purity while simultaneously delivering it without harm. Because of its value, there are several different concerns to take into consideration when selecting the proper regulator for an operation.

The first thing to evaluate when choosing a regulator is the level of purity that is required in the application. The three most common purity levels required are: general purpose, high-purity, and ultra-high purity.

For example, if an application requires high-purity gas, then a high-purity regulator should be employed in place of a general-purpose or other unsatisfactory regulator. At the very least, regulators that are utilized in delivery systems should be washed by the distributor to ensure both cleanliness and safe utilization.

Another matter 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, on the other hand is employed for stainless steel, brass, and various other 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 less difficult to purge, thus allowing the removal of moisture and impurities. In addition, barstock has a smoother internal surface which reduces the quantity 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 applied most frequently in pressure regulators. In some higher-purity applications or in situations where brass is incompatible with the gas being utilized, other materials such as stainless steel are used. Gases with corrosive properties sometimes call for corrosion-resistant materials for all wetted parts, but flammables and inert gases are generally compatible with brass and most other materials. 316 stainless steel is most often employed in circumstances that require 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 enabling them to maintain noncorrosive gases with higher purity levels. For semi-corrosive or corrosive gases or gas mixes and higher-purity demands, stainless steel should be utilized. For gases that are highly corrosive, Monel or Hastelloy should be the materials employed as they allow for more corrosion resistance.
