Has anyone seen the new piping Diagram for Dunkirk's D-250 steamer
Look here:
This is just plain nuts. I'm all for proper near boiler piping, but this seems outlandish. Also, I bet the joined returns are putting a nice amount of stress on the boiler. Like most steamers, nearly all of these in the field are piped incorrectly, even by conventional standards.

They'd better take a look at @DanHolohan 's books!

If you read the manual they discuss swing joints on the steam header so you don't damage the boiler. and the fact that you only need one riser.
They mention connecting the return at both ends of the boiler. Anyone with a clue is going to do that with swing joints as well.
It is funny looking I have installed those in the past.
I think they are showing that you can pipe the supply and returns from either end of the boiler.
But they could be more clear.

What about someone that has almost a clue Ed? I might interpret this as connecting both returns like this:
Just matching up the left side with the right side because the right side is blocked by the boiler in Figure 35. That red pipe does not include swing joints as I interpret the drawing. I believe that there is a flaw in the diagram because it does not show the right side, so we can properly install the swing joint on the return connecting pipe. I think there may be some failing boilers as a result of this figure 35 drawing.
I wonder what the Dunkirk folks might think about this drawing?

I do like the term "Header Drip" instead of that other misleading name for it

it isn't misleading if it is 2 pipe.

I'm not sure of that honestly but I'll think about it

Anyone with a pipe fitting brain is not going to pipe between two fixed points (threaded joints on both ends of the boiler) especially with larger pipe without swing joints.
In the first place you cant do it without "springing" the pipe if you use 1 union or you would have to use flanges or two unions. The return is likely to be 2",2 1/2 or 3" and it doesn't bend very well.
Its no different than the guys that don't read the manual and put in a steam header in line with no swing joints.
