Thought maybe you guys would like to see what industrial/commercial plumbing looks like.

This first one is from a tenant improvement that involved hundreds of feet of trenching, as much as seven feet deep. This is the shallow end, but it's not completely dug out in this picture.



This is from a hotel I recently worked on. Since I'm a foreman, I spent several months on this one without touching a tool. Then suddenly I was in charge of getting the boiler room done, as for some reason the guy who had been working on it was transferred to another job. So this is where we started hanging pipe. This is 6" Sch. 10 stainless, which is what the main is made out of. Most of the branch piping is CPVC. There are 3 1.3 million BTUH boilers, and on the bottom of this piping, you can see 3 3" butterfly valves.



Next is some work I did myself. Normally, I'm content to stand around barking orders, but as the end of the job approaches, and manpower is diverted to other jobs, the foreman often has to do whatever remains. This is condenser water from some cooling towers that you can't see to the right, going to heat exchangers for some monster freeze-driers (lyophilizers). On the right is 2" copper going up, and there is 1-1/4" copper going down to the heat exchangers. The reason that the piping goes way up in the air and back down instead of following a more direct path is that they wanted to be able to walk between the cooling towers and the lyophilizers.



Next one is also me. I didn't do most of this system, but I did get another guy to take pics on the parts I worked on. Here I am silver-brazing a 2"x1" copper tee for a compressed air system. We must have run a thousand feet of brazed 2" copper in this building. There's more than 600' in just this room where I'm working. Incidentally, this is an A-32 air-acetylene tip, for those who care.



Hope you like them.

Yes, but we often use 5% silver unless 15% is specified. Not quite as expensive, but still not cheap. The lyophilizer guys were using something like 65% silver, which I imagine costs plenty.

Thanks for sharing the photos! That is some nice looking work.

I'll bet it's good for the workmen to see that the foreman can do good work too! Hope they see what their able leader can do...

That copper is glowing - isn't that way too hot, even for silver solder?

Plumbers generally use BCuP alloys, which require more than 1150 degrees F. So actually, I would expect the copper to be glowing brighter than that when it's ready to braze. Usually it's cherry red when it's hot enough.
