Specialty Gas Distribution Equipment for Cincinnati

Specialty gases are only as effective as the equipment employed to propagate them. The purity and precision these gases are known for may well be diluted should they not be supported by the necessary pressure and flow control and absent the means to verify gas consumption.

Since few would contest that compressed gases, on account of their general characteristics, should be conveyed in high-pressure gas cylinders, managing that pressure in normal use is often an afterthought. One can’t deny the considerable distinctions 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 we provide at Wright Brothers offer the kind of quality in materials, design, and assembly that distinguishes them from common industrial gas equipment. While pricier, this equipment usually has a value that far surpasses its price. PurityPlus® regulators, mind you, typically use diaphragms made of stainless steel, not rubber. Rubber diaphragms are prone to soaking up moisture and impurities, then off-gas such contaminants as the cylinder supply pressure dips. This can wreak havoc in carrier gas flow and instrument response.

Equally annoying is the problem of crawl. As the pressure in a gas cylinder is made to drop, the pressure on the diaphragm is also lessened, and the outlet pressure can go up. To offset this action and tamp down its effects, it is seriously recommended that a two-stage PurityPlus® regulator be applied. The manufacturer presets the first-stage pressure reduction, normally in the range of 300-500 psig, giving users the ability to  monitor the final outlet pressure in the second stage. Setting an intermediate pressure weakens the crawl effect by the second stage so  it’s virtually eliminated until the cylinder pressure goes below 150-200 psig.

Its worth comparing this, now, to an industrial gas single-stage regulator. As a result of the single-stage design, the single diaphragm undergoes a nonstop lessening of supply pressure along with a relaxed but unbroken increase in outlet pressure that may fluctuate as much as 10-15 psig.

These are only a couple of examples that show clearly why the right gas also needs the right gas equipment. Contact us online or call us, Wright Brothers, at 800-637-2222.
