Steam Basics Part 5: Condensate Drop Leg and Pipe Size

Steam Basics Part 5: Condensate Drop Leg and Pipe Size

A few weeks ago we discussed the steam pipe size entering a shell and tube heat exchanger, also called a convertor. This week we turn our attention to the condensate outlet. A customer recently asked, “I was told to pipe a 14-inch condensate drop leg from the bottom of a steam-to-water heat exchanger to the F&T trap inlet. What happens if I ...?”
