I’ve got a pretty cool job. I’ve written about this before…in fact, as recently as last week, in a piece about workplace safety, and how EXAIR is all over it, all the way. Brian Farno also blogged the other day about how EXAIR recognizes, appreciates, and celebrates achievement. Like usual, actually.
So yeah; this is a pretty cool job. And, just to put that into perspective, my first “grown up” job set the bar pretty high: upon completion of Naval Nuclear Power School, I was assigned to the initial manning crew of a new construction Trident submarine. When I got there in the spring of 1987, “tha thirty-five boat,” as the future USS Pennsylvania (SSBN-735) was known, was ON the pier (not NEXT to it) and we boarded through hull cuts in Engine Room Lower Level & the Torpedo Room. For two years, we worked with shipyard personnel to install, test, & certify all ship’s systems, and then took her out in the summer of 1989 for a rigorous series of sea trials. I wish there were words capable of conveying the extent of “job satisfaction” we felt when we submerged for the first time, and the whole ocean stayed outside the boat.
I was reminded of this the other day when I saw a news account of the bow section of a submarine being transported via barge from the shipyard that fabricated this section, to the shipyard that’s assembling the boat. Here’s a video clip of one such transit, from about a year ago:
I’ve written before about how compressed air is (and isn’t) used on board a submarine at sea. Compressed air is also used, for some pretty neat stuff, in their construction & service. And EXAIR Compressed Air Products are in the mix:
*Sometimes during work on a piping system, it’s not possible to isolate a particular section with valves, so a freeze seal is applied: a collar fits around the outside of the pipe, and very cold fluid is circulated through the collar. This freezes the liquid inside the pipe, forming a “plug,” which allows you to work on the piping downstream, just the same as if you had shut a valve there. One method of doing this is with liquid nitrogen…you take a big tank of the stuff to your work site, implement all the safety precautions you need to handle pressurized liquid at -321°F (spoiler alert: it’s complicated,) make up your connections, hope they don’t leak, and activate the system. Depending on the length of the job and the size of the tank, you may need to change it out…which, again, is complicated. And yes, I’ve done it.
Or, like several shipyards are doing currently, you can install an EXAIR Maximum Cold Temperature Vortex Tube to the collar, run a compressed air line to it, and you can supply cold air as low as -40°F, which will freeze a plug in that pipe for as long as you keep your air compressor running.
*Another application has to do not with the equipment, but the people working on it. Welding is a hot job – there’s really no way around it – and welding in tight spaces can present real issues for the folks involved. Fans and blowers can provide a good amount of ventilation, but they also take up some room, which there may not be any to spare.
Enter EXAIR Air Amplifiers – they’re compact, lightweight, and use a small amount of compressed air to blow a high flow of cooling air, right where it’s needed.
These are just a couple of examples of how a large industry – shipbuilding – is using EXAIR products to capitalize on efficiency in a challenging environment. Regardless of your situation, if you’d like to learn if EXAIR can help out, give us a call.
