Specialty Gas Distribution Equipment for Albany

Specialty gases really aren’t any more efficacious than the devices employed to distribute them. The purity and precision these gases offer may well be compromised in the absence of proper pressure and flow control and without the provisions to identify gas consumption.

While it’s pretty much a given that compressed gases, given their general characteristics, are transported in high-pressure gas cylinders, controlling that pressure in typical use is often relegated to an afterthought. You can count on there being noteworthy 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 available from Noble Gas Solutions deliver a level of quality in materials, design, and assembly that differentiates them from ordinary industrial gas equipment. While higher priced, this equipment usually has a value that far surpasses its price. PurityPlus® regulators, for instance, most often use diaphragms made of stainless steel rather than rubber. Rubber diaphragms are prone to picking up moisture and impurities, then off-gas such contaminants as the cylinder supply pressure falls. This can impede carrier gas flow and instrument response.

Equally disconcerting is the problem of crawl. As the pressure in a gas cylinder is lowered, the pressure on the diaphragm is also lessened, and the outlet pressure can rise. To compensate for this action and restrict its effects, it is strongly recommended that a two-stage PurityPlus® regulator be applied. The manufacturer presets the first-stage pressure reduction, normally between 300-500 psig, while the user is allowed to  control the final outlet pressure in the second stage. Setting an intermediate pressure puts dampers on the crawl effect by the second stage so  it’s nearly a done deal until the cylinder pressure drops below 150-200 psig.

Compare this to an industrial gas single-stage regulator. Because of the single-stage design, the single diaphragm sees a continuous lessening of supply pressure as well as an unhurried but continuous rise in outlet pressure that can change as much as 10-15 psig.

These are just a couple of examples proving that the right gas also demands the right gas equipment. Contact us online or get in touch with us, Noble Gas Solutions, at (518) 465-5229.
