Industrial Piping Job

[JCM 9,130]

This is a recent piping job showing 3'' and 2 1/2 '' copper tubing piping from outdoor chiller to 2nd floor water manifold for a furnace.Unfortunately the outdoor piping was done during very cold temps and windy which made the soldering difficult trying to keep the flame directed to the proper area on the fitting to allow the correct temp to allow the solder to flow. This is the type of work I did 30 plus years ago fitting and soldering joints this large and knew what I was getting myself into but did bring back many memories. The only bad part part if you notice the red rag on the outside unistrut frame work supporting the diverter valve and associated piping was right at the end I stood up knowing there was a 1/2'' threaded rod and hanger for a support and hit my head getting out of there and received a nice gash in the top of my head. Hope you enjoy the pics.

Beautiful work Sir.

 

Hope your head heals well and soon.

At least you know it couldn't have done any internal head damage.

So awesome!  What a monster chiller!  What kind of torch are you using for piping that large, oxy-acetylene?  Have you ever dabbled with the electric clamp on “torches” for copper?

Kevin, outdoors when windy I used an LP Turbo torch and indoors an Acetylene with a large # 5 tip, no oxy. Have never used clamp on. I have not done this type of work this big since before 1987 but as they say it's like riding a bicycle you never forget how. Each piece of copper was half round filed on the inside and a slight bevel on the outside then sanded , fluxed and soldered. That size copper does not want to fit together that easy or not at all without that prep work.   Thanks for your interest.

I’ve dabbled with big copper at my old house a bit, but just fixing traps and vents.  The entire drain system was copper, even the 3” runs!

I see all those coils and all those trees and down in a hole with close walls. That equals clogged coils and high head pressures. Maintenance staff better stock up on Nu-Brite!

@squonk    I believe the next phase of that job is an entire roof along the outside of that building to cover all that work. Good Call.

[squonk 41,029]

I hope the roof is not to close to the top. All that hot air has to escape. I've seen fences put around those. Fences catch paper and leaves and then they get sucked into the coils.
