drop headers

Oh boy, here we go again!

Try clicking on the library located on the tool bar to the left I belive there are some photos there. Also, try clicking on the search button above and then type in "Drop Header". This has been a very interesting and highly debated topic in the past. My opinion is if you cannot maintain the minimum distance required from the normal water line to the invert of the header then a drop header can help, I however never felt the need except in an industrial application which by the way must be done (in most cases) or were you connect multible boilers together into a common header. Don't misunderstand I don't claim they are or are not effective in providing drier steam or ease in installation I'm just saying we've done a bunch of em but all were for very large boiler(s).

drop headers

What is the advantage of a drop header? I've been in the trade for 22 years, and I know how to construct a steam header, but we(the contractors in this area) have never used drop headers. I'm thinking it must be so condensate is not running back against the steam, but I haven't had any problems doing it the other way. Thanks for your time.

Drier steam is the big reason. It can gain headroom or make way for other piping, of the breeching, and can make piping the swing joints easier. By rolling over the top, the swing joints make the spacing between the risers easier to pipe up with standard nipples. Rolling the swing joints can widen or narrow the gap and you can easily "make 'em fit up"

Steamhead

I use them

because they're much easier to put together, like Al says. You save a lot of time and aspirin by getting those two street ells to drop into your header. Try one on your next small boiler job and you'll see what I mean.

The extra swing joint also helps relieve expansion stress at the boiler sections, which can increase their life.

I'm bulking up

for our next match . Where did you get the glass bushings ? I piped up a steam boiler for a college class and those things could show the students what's actually happening . I was thinking about fabricating glass coil plates , but your idea looks better .
