Main vent piping

Sizzlaw Member Posts: 11

April 2010 in Strictly Steam

I am adding two vents to my one-pipe steam system. The piping from the main to the vents is 16 inches long and I can use either 3/4 or 1/2 inch pipe to connect to the vents (the vents are equipped with both size threads). Is there any advantage favoring one size over the other?

Go large.

8.33 lbs./gal. x 60 min./hr. x 20°ΔT = 10,000 BTU's/hour
