Black Pipe - Heat Output

Einsiedler_2

Anyone know where I can find the btu-capacity of black pipe.

(using multi rows of black pipe as radiation in large barn)

based on 180F e.w.t

thanks in advance,

Try the\" Hot Tech Topics \" Section

of this website. This question comes up on occasion, and I think there is a list of btu outputs there.

btu's on bare steel pipe

These figures should be pretty accurate.
1-1/4 steel pipe 107btu/ft
1-1/2 steel pipe 124btu/ft
2 steel pipe 150btu/ft

all based on 180 e.w.t.
Hope this helps

Ideally

you need to know temperature, delta t, flow rate, and surrounding air temperature.

The Burnham Heating Helper pocket guide has some info on page 47.

1" steel in 70°F air temperature 180° pipe temperature= 90 BTU/ ft. Not a lot of heat, really. Add some fins!

Thanks guys.

Looks like I'll need 4-rows of 2" around this 120'x120' shop.

Fin option was a good one (Thanks HR), but customer does not want anything that will clog up, only wants clean steel pipe.

once again, I am in your debt...

Well then

I would think infloor would be the way to go.High
mass slab,low water temps,on a continous circ injection system,match to a condensing boiler of your choice.

Ok,if floor been pour,forget I even mention it.

Sorry, I was thinking out loud.I'll go back to bending metal now.
