Specialty Gas Distribution Equipment for Atlanta, GA

Specialty gases are effective only in the context of how effective the apparatus is that’s employed to disseminate them. The purity and precision these gases deliver are likely to be tempered should they not be supported by proper pressure and flow control and absent the provisions to corroborate gas usage.

While the presumption is that compressed gases, given their general characteristics, are delivered in high-pressure gas cylinders, regulating that pressure in standard use is oftentimes treated as a matter of secondary importance. There are major differences between cylinder regulators intended for oxy-fuel cutting and welding, most purge gas applications, and specialty gas use.

The PurityPlus® gas pressure-reducing regulators and flowmeters inventoried by Sidney Lee Medical & Scientific Gases present the kind of quality in materials, design, and assembly that differentiates them from ordinary industrial gas equipment. Though higher priced, this equipment commonly carries a value that goes well beyond its price. PurityPlus® regulators, mind you, typically use diaphragms made of stainless steel rather than rubber. Rubber diaphragms are inclined to soak up moisture and impurities, then off-gas these contaminants as the cylinder supply pressure dips. This can seriously effect carrier gas flow and instrument response.

No less bothersome is the issue of crawl. As the pressure in a gas cylinder is made to fall, the pressure on the diaphragm is also reduced, and the outlet pressure can rise. To offset this action and limit its effects, it is unequivocally advised that a two-stage PurityPlus® regulator be used. The manufacturer presets the first-stage pressure reduction, usually between 300-500 psig, giving users the ability to  adjust the ultimate outlet pressure in the second stage. Setting an intermediate pressure reduces the crawl effect by the second stage so  it’s almost a done deal until the cylinder pressure drops below 150-200 psig.

Compare this to an industrial gas single-stage regulator. As a result of the single-stage design, the single diaphragm experiences a unbroken lessening of supply pressure along with an unhurried but continuous increase in outlet pressure that could vary as much as 10-15 psig.

These are only a couple of examples that show clearly why the right gas also necessitates the right gas equipment.
