Check this link if the pictures don't work. I'll fix them when I get on my real computer.



Nickdu had a thread here a few weeks back. Noise, and performance issues with the steam boiler. Well...the pictures tell the story.



When we left, the system was whispering along. The exit velocity went from 45 feet per second, with the old piping, to 10 fps with the new setup.

Am I the only one that gets the same picture enlarged for every picture I click on?

Somebody

 came up with a workaround last week.  If you right click the pic and open in a new window, the pics are OK.



Lookin good JStar!  What do you call this "special elbow" that you used?  Can an elbow like this be used for a drip?  http://www.heatinghelp.com/forum-thread/143174/Can-there-ever-be-too-much-Main-Venting#p1278332

Fitting

They are Tees. One is a 2 x 3/4 x 2 tee. You phrase it Run x Run x Bull.

Drop header

Killer Drop header Joe, I second Steamhead, it belongs in the Library, you got my vote!

JStar

Thanks

Felt real good to stand back and look at this one when it was all done. Three inch cast iron brings a real presence to the room.



The only pipe we threaded was the returns. Everything else was nipples. We bring about 4 sets of pipe, and wind up using 20 short nipples.



We're going back to install a Vaporstat and to upgrade the existing main vents.

Sweet piping

JStar, this thing looks great.

I have been drooling over the pictures you put up on facebook.  I'm still scratching my head on how you connected the drop header from RS elbow to the LS tee.  If you build it up from the supply pipes out of the boiler then continue to build "over and down", are you using a close nipple with opposite threads?? 

I'm sitting here trying to work this stuff out in my mind, but maybe I've missed something really obvious!

Piping

We started at the RS opening, elbowed over and down. Spun the first tee in place. Then came up and connected the LS opening. The RS union is just for service and symmetry.

Beautiful Work!

The best part about doing work like that, is, the customer sleeps good at night, and so do you.

Steve Nichols

Ah yes,

now I get it. I was working in the wrong direction when I was thinking about it.  Thanks for setting that straight.  I'm trying to get ideas so during next summer I can redo some of the piping my contractor did.  The first thing I want to do is use both supplies from the boiler to knock down the exit velocity.  I was wondering about how to join all the bits 'n pieces together, and it looks like unions are the way to go to keep things clean and simple.
