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. 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 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 lower
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 also
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 many different matters
to consider when selecting the correct regulator for a
job.
The primary thing
to evaluate
when selecting a regulator is the purity level that is required 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 used
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 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 employed 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 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
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
that are used since they allow
for more corrosion resistance.
