Your safety and the reliability of your equipment are important to us
To better meet the demands of our customers, we perform a variety of auditing, painting and repair tasks for your cylinders and its monitoring hardware so that you know your product meets safety requirements and performs to your needs.
At Rocky Mountain Air Solutions, we believe that cultivating a culture of safety among our people will help you keep your focus where you need it most – on your business.
We perform low- and high-pressure DOT hydro testing along with paint stripping and reapplication to make your certified cylinders look brand new and verify they are ready for use.
How do you test cylinders to ensure they are safe?
At Rocky Mountain Air, we break down testing into a variety of steps so that we are actively ensuring cylinder service through every step of the way. The tester begins every cylinder test with a visual inspection of the cylinder to spot any obvious defects in the container. Then, we test the cylinder on a specialized piece of equipment in one of two ways: hydrostatically or ultrasonically. Cylinders tested hydrostatically are filled to the brim with pressurized water to determine if the cylinder will expand properly when it is filled. An ultrasonic testing machine scans the outer and inner facings of the cylinder walls to look for defects and cracks which could not be seen otherwise. Both methods are approved by the DOT to ensure the safety of cylinders filled in the USA. If the cylinder passes inspection, a stamp is applied to the shoulder of the cylinder starting the month and year the cylinder was tested, as well as, the RIN number which identifies the specific testing facility which examined that cylinder.
How do you fill cylinders with compressed gas?
There are massive facilities across the country called air separation plants. Their purpose is to take in the air that we breathe and separate each gases's atoms from the air and purify it. Once the gas is separated, it is converted into liquid product and shipped to various companies in large liquid tanker trailers. We store that liquid product in large ground storage units until ready for use. For liquid use customers, we syphon out some of the liquid product from the large tanks and put that liquid into smaller transportable vessels that we call Dewars or liquid cylinders. For high pressure applications, we use pumps to convert the liquid product back into gas and then push the now gaseous product into the cylinders that we provide.
Do you accept partially full cylinders of gas or liquid product as a return?
Unfortunately, our processes, as well as the regulations of the FDA on certain products, prevent us from accepting partially full items or items that are marked as full, but have left the company's possession. We will not accept a cylinder with some gas remaining as a return because we are committed to maintaining the purity and safety of all of our products we provide to our customers and prevent potential adulteration or contamination.
