Western Railroad Discussion > Refrigerated Argon Anyone?Date: 04/19/18 11:47 Refrigerated Argon Anyone? Author: Fiftyfooter Boc Gases tank car!
Sounds like Argon is maybe used as a shielding gas for MIG and TIG Welding processes and plasma-cutting. Interesting how there are no top valves or structure on this guy! Edited 1 time(s).

These cars sometimes vent to the atmosphere,notice the pipes wrapping up towards the left side, but relatively speaking, Argon is fairly inert, and though placarded , not really "nasty".

Argon and neon walk into a bar. The bartender asks "What is this some kind of joke?" The two gasses don't react. Date: 04/19/18 16:47 Re: Refrigerated Argon Anyone? Author: roustabout Portland & Western gets these cars for a customer near McMinnville. Once in a while some citizen sees a car venting and gets concerned about it. And we had one come in that had a broken pipe or valve and that equipment box was covered in a thick layer of ice.

The contents are allowed to vent slowly to atmosphere, which is the refrigeration apparatus at work (no moving parts), along the same principle as steam ejector air conditioning. > but relatively speaking, Argon is fairly inert, Argon is considered inert, although it will react under very extreme conditions (high temperatures and high pressures), so the only danger from breathing argon from cars like this (or helium, neon, krypton, or xenon) is the displacement of oxygen in your lungs. Displacing oxygen for a long enough period of time is called "asphyxiation", but the amounts which can be taken in by being near these cars when they are outdoors aren't great enough to cause that. Radon, on the other hand, is radioactive. Date: 04/19/18 19:59 Re: Refrigerated Argon Anyone? Author: portlander It's also the preferred gas to use with draft wine!

Cascade steel probably uses it for blanketing or ladle stirring. Date: 04/21/18 03:23 Re: Refrigerated Argon Anyone? Author: DubyaM EricSP Wrote:

Nitrogen may be cheaper but argon is used (http://www.airproducts.com/industries/metals/ironsteel-production/integrated-mill/product-list/ladle-metallurgy-integrated-mill.aspx?itemId=12E4C7D41FC042B885ABF7536E7C5FCB), probably when they want to control nitrogen content.

If you have double-glazed windows, chances are the gap between the 2 panes is filled with Argon as it has a low thermal conductivity. |
