Today’s HVAC and process engineers have lots of choices when it comes to pipe sizing programs for steam and condensate applications. Put in a load and a pressure and out pops the answer. But ever wonder about how that answer is generated? Or if there are times when it might be suitable to choose another pipe size....?
Read MoreWhen using a sizing program to select steam pipe sizes, the engineer or contractor is asked to fill in the capacity, the steam pressure, and the velocity required. The answer is ....
Read MoreA 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 ...?”
Read MoreThis week we take a look at the vacuum breaker on a steam-to-water heat exchanger. Steam-to-water heat exchangers, or steam heating coils with on-off or modulating control valves, require a vacuum breaker. This simple and relatively inexpensive device may save ...
Read MoreWhy do you tend to use low-pressure steam in HVAC and domestic water heat exchanger selections? When selecting a heat exchanger, the diameter is determined by the design flow rate and ...
