Steam Repipe

ChrisJ

Yes but hat still owes me $100 for betting my wife wouldn't allow me to paint all of the radiators flat black.

I think the point has been lost in this post. I'm not saying upsizing is "BS", nor am I asking for praise. The "no love" comment was meant to be comical. I love searching the wall at the end of the day for install pics, so I was excited to post mine at the end of a long day. I repiped the existing piping to meet manufacturers specifications (and beyond), as is what I proposed for this particular project. The boiler is now piped and working correctly. There are still improvements to be made, and they will be made. Here's a 3" header on and IN6 I installed, just for you @Hatterasguy

Really nice tall risers out of that boiler too! Very nice

ChrisJ

Ah,
Must be nice to have so much money you can just turn down work all the time eh?

Where Is your business located @Hatterasguy?

Doubling the pipe size is poor workmanship according to Starbucks books on steam heating. I will post the page tonight on this thread.

Let JoeS and Dave and Ezzy know. I'm sure they will be very interested.

BTW, "doubling" is the based upon the volume, not the diameter. But, you already knew that.

Based on a 3" having a surface area of 7 inches and a 2" having the surface area of 3.14 inches, I'm betting he did know that.

A 3" is double the volume of a 2".

Charlie from wmass

I am not sure. He may be saying 4" instead of 2".

I need to teach you guys about the trombone header.

I suppose that might make this a French Horn Header.

That's a church organ header!

See Page 19 for pipe volume

. @Danny Scully does great work.......ive done a 2 inch header a few times...in a pinch customer had limited cash....home was 30F during last years 0F couple of weeks....this was a Williamson GSA 075.... i wouldve done it i 3 " inch , but with the cash shortage and time constraint....i decided to pipe in 2" inch ....i bushed down at boiler tappings....i dont know the FPS on this ....anyone have a chart for FPS of steam? i have a GSA 100 with 3 inch and no drop header.... and i have another GSA 075 piped regular with proper swing joints and all ....really quick one afternoon.......
no one ever mentions my name @Paul S when it comes to steam....lol ....i try my best for you guys....when i do a steamer ....seriously.....ill keep posting....Paul S

@Paul S. The gsa 75 Will give you 19.22 fps @ 1 psi when piped with a single 2" boiler riser and 2" header.

@Hatterasguy - That kind of approach works great on a 16 penny nail. Not so much with people. Ask me how I know that.

Very nice Trombone @Paul S

Depends on the pressure. I find this helpful (they also have a mobile app.)

Try looking at different pressures (even negative ones) and see how it affects velocity.
