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

Compressed gas producers like Delille Oxygen Company frequently put forth serious effort to fulfill their Columbus 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 method of shipping, these gases will eventually face handling, distribution, and regulation by the Columbus 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 differ from being extremely 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. Likewise, the employment of certain hazardous gases can produce safety hazards if they are not used with the proper equipment.For this reason, Delille Oxygen Company works hard to ensure that we are always using the right equipment and that our Columbus customers are as well

The function of gas regulators in gas delivery systems is to reduce the pressure from a high-pressure origin to a pressure level that is able to be used. The right regulator can preserve gas purity while simultaneously delivering it without harm. Because of its significance, there are a lot of different matters to consider when choosing the correct regulator for a job.

The primary thing to evaluate when selecting a regulator is the purity level that is called for 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 requires high-purity gas, then as a result, a high-purity regulator should be used in place of a general-purpose or other inadequate regulator. At the very least, regulators that are applied in delivery systems should be cleaned by the provider to ensure both cleanliness and safe use.

One more matter that needs to be taken into consideration when deciding on the correct regulator is the regulator’s body type. The bodies of regulators can be either generated from barstock or forged. Forging is utilized with only brass; barstock, on the other hand is utilized for stainless steel, brass, and various other materials. There are quite a few 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. In addition, barstock has a smoother internal surface which lessens 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 most often in pressure regulators. In specific higher-purity operations or in circumstances where brass is incompatible with the gas being employed, other materials such as stainless steel are used. Gases that have corrosive properties might need 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 utilized in circumstances that call for 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 enabling them to maintain noncorrosive gases with higher purity levels. For semi-corrosive or corrosive gases or gas mixes and higher-purity needs, stainless steel should be used. For gases that are highly corrosive, Monel or Hastelloy should be the materials utilized since they allow for more corrosion resistance.
