Steam Piping Best Practices | CleanBoiler.org

Steam moving through a line at high speeds picks up condensate in the bottom of the pipes, much like wind blowing across a lake forms waves. When the high speed steam and condensate come to a bend, such as a 'Tee' or 90 Degree turn, the steam makes the transition, but the water slams into the side wall of the pipe.
