Steam Take-off piping

5_Tomcatcavey

my boss always buys prefabricated near-boiler piping kits. Because of this he chose to pipe the steam take-off from our boiler like this. How much of an issue (if any) will this cause for the system?

The two steam risers should be connected to the header separetly not teed together. Both risers should be fed before the equalizer.

As long as the boiler isn't surging it could be OK but it sure is going to look weird. In my opinion it depends on how much counterflow you might have in those mains.

Are you planning on putting a plug in that Tee?

Since it's not even done yet, I'd undo it all and re-do it with both mains coming out of the header like it should be.

To clarify, the boiler piping kit came with one riser and one takeoff from the header. My boss chose to use that single takeoff to double back and connect to the old header which has two takeoffs. The equalizer is out of frame to the left of the picture. Sorry if the picture doesn’t capture everything.

I agree with EBEbratt. Would like a fuller picture before I say 100%. Mad Dog

Even if counterflow condensate isn't an issue per se there are a lot of reasons you could have problems getting that to heat evenly.

Don't be "that guy". Re-do it as @mattmia2 suggests.

I'd use both boiler taps but that's me.

The boiler manual will tell you if you need to use both risers and what size the single or dual risers need to be. In some cases you can use 2 smaller risers in place of one larger riser. On very small boilers like that 2 risers usually isn't necessary if the rest of the near boiler piping is correct but the manual or steam velocity calculations is the final authority.

What's the old quote?

"If you haven't got the time to do it right how are you going to find the time to do it over"

No one can predict if it will work or not but it is not right

If you leave it that way it may work but it may not work.

Then you will have to take it all apart and redo it.

If you also put a drip back to the boiler return off the end of that extra header, it should be OK. Otherwise you may have problems. But why? Surely it might have been possible to find a harder way to pipe that?

Just put a 45 and a nipple up to those tees and similar to hook up the equalizer.

Done!
