Compressed gas distributors like Mississippi Welders Supply Co., Inc. often put
forth serious effort to fulfill their Winona 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 shipping method, these gases will eventually
face handling, distribution, and regulation by the Winona consumer. Throughout this,
the gases see several different types of gas equipment and methods of handling that will either lower
or preserve its purity.
Gas handling systems can vary from being extremely
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 an item
that should never be underestimated. Additionally,
the employment of certain toxic gases can produce
safety hazards if they are not employed with the proper
equipment.because of this, Mississippi Welders Supply Co., Inc. strives to ensure that we are always using the right equipment and that our Winona 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 sufficient for use. The correct regulator is
capable of maintaining purity of the gas while simultaneously
delivering it harmlessly. Because of its significance,
there are a lot of different elements
to contemplate when deciding
on the right regulator for a
job.
The first matter
to evaluate
when choosing a regulator is the level
of purity that is called
for in the application. There are three categories under which these requirements
usually fall: general purpose, high-purity, and
ultra-high purity.
For example, if an
application calls for high-purity gas, then in response, a high-purity regulator should be used
in place of a general-purpose or other insufficient
regulator. At the very least, regulators that are employed
in delivery systems should be kept clean by the supplier
to assure 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
used with only brass; barstock, however is utilized for stainless
steel, brass, and other materials. There are several reasons for which barstock bodies are chosen
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. Likewise, barstock has a smoother
internal surface which reduces the number
of contaminants that are retained inside. To conclude, 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 used most frequently in pressure regulators. In some higher-purity applications
or in cases where brass is incompatible with the
gas being employed, 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 commonly
employed in operations that
require corrosion-resistant materials.
Forged brass bodies are most often employed with the lowest-purity gas, and in the lowest-cost
regulators. Brass barstock bodies, on the other hand,
have smoother internal finishes and smaller internal volumes giving them the ability 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 used.
For gases that are highly corrosive, Monel or Hastelloy should be the materials
utilized because they lead to more corrosion resistance.
