Specialty Gas Distribution Equipment for Winona

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 provide stand a good chance of being reduced in the absence of the required pressure and flow control and lacking the means to substantiate gas use.

While not many would argue that compressed gases, by virtue of their prevalent characteristics,ought to be conveyed in high-pressure gas cylinders, regulating that pressure in typical use is frequently relegated to an afterthought. One can’t deny the marked differences between cylinder regulators designed for oxy-fuel cutting and welding, the usual purge gas applications, and specialty gas use.

The PurityPlus® gas pressure-reducing regulators and flowmeters we provide at Mississippi Welders Supply Co., Inc. offer a level of quality in materials, design, and assembly that sets them apart from standard industrial gas equipment. While higher priced, this equipment tends to have a value that far exceeds its price. PurityPlus® regulators, mind you, most often have diaphragms made of stainless steel, not rubber. Rubber diaphragms have a natural tendency to soak up moisture and impurities, then off-gas the contaminants as the cylinder supply pressure slides downward. This can wreak havoc in carrier gas flow and instrument response.

Similarly troubling is the matter of crawl. As the pressure in a gas cylinder is brought down, the pressure on the diaphragm is also lessened, and the outlet pressure can rise. To compensate for this action and curb its effects, it is seriously advised that a two-stage PurityPlus® regulator be utilized. The manufacturer presets the first-stage pressure reduction, usually in the range of 300-500 psig, giving users the ability to  adjust the final outlet pressure in the second stage. Setting an intermediate pressure weakens the crawl effect by the second stage so  it’s just about a done deal until the cylinder pressure slips back below 150-200 psig.

Now, by way of contrast, consider an industrial gas single-stage regulator. Because of the single-stage design, the single diaphragm experiences a unbroken lessening of supply pressure in association with an unhurried but unbroken increase in outlet pressure that could vacillate as much as 10-15 psig.

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