Automatic Steam Trap Drain Point Location

Is the drain point on the upstream or on the downstream of the automatic steam trap? Thanks for your help.

I would think that it should be exactly where the paperwork says it should be. Or are you the kind of guy that believes that real men don't use paper.

Think it through.

  1. What is the job of the trap?
  2. What is the job of the drain point?

The answer will drop out.

You ask some really "interesting" questions.

Do you understand the concept of "upstream" and "downstream", in relationship to the trap?

I'll help you a little. One is before the trap and one is after the trap. When you get this sorted out, the answer may come to you. If not, just let me know and I'll recommend some books that you may not have read yet.

I know the "upstream" meaans "before" and the "downstream" means "after".

I suppose that we can know whether or not the automatic steam trap works out of order if the drain point is on the downstream of the automatic steam trap by opening the drain point to confirm that there is no steam leaked. But I'm told that it should be on the upstream, so I'm confused.

I'll appreciate it if you give me some clues or the answer.

Steam traps will generally have manual blowdowns (drains) upstream of the trap to get rid of excess condensate during start-ups. Once the piping and traps are warmed up, the manual blowdowns are shut.
