Near boiler piping diagrams

Marz

I'm looking for some diagrams on the do's and dont's for near boiler steam piping. We ran into a recent boiler in which the steam entered the main via a bullhead tee. Was hoping to print out some diagrams for everyone here. Any help is appreciated.

I know that Hatt, but I'm looking for the do's and don'ts. Someone here recently had a link that showed a red X on the takeoffs to the mains ect...

I agree and thank you. In this case the main is split in half by a tee. My opinion is that the tee should be removed, and each side of the tee should have its own takeoff. As it stands now, the steam runs into the tee and has to go both left and right.

The argument that was brought to me is that it has been that way for years. My argument in return was that the new boiler will make steam much faster. With the increase in velocity I believe it will become noisy. The problem is it will take X $$ to do it right. My plan is to print out that diagram (If I can find it) and hang it in places where people here get the hint.

About 3/4 of the way down MichaelCorman attached a pdf document with some piping information, I think it's what you are looking for.

What's the best fitting/setup to use in the Hartford loop?
Tee off, nipple into 90 elbow or Y-pipe?
