CAPPA Tech Tips—Annual Steam Outage

There are likely several hundred or more on your campus, but are they properly sized? Pressure gauges typically have the specified isolation valve (or trumpet valve), snubber, or pig tail. Proper sizing can present serious issues when miscalculated. The accuracy of the gauge is not always what is shown on the gauge face. Most bourdon tube mechanical pressure gauges are accurate between 1/4 and 7/8 of the gauge range. It is not a linear relationship. For example, the gauge shown to the right would be most accurate between 15 psi and 52.5 psi.

CAPPA Tech Tips – Steam Traps

If you have a steam system – you have them. Understood by few, they are required for safe & efficient production and distribution of steam. Small or large they can make or break your system and are frequently taken for granted (or completely forgotten). Steam traps are installed in lines to drain condensate from a system without allowing the escape of steam (MM3 & 2 124). There are several types of traps, and the application (not the pipe size) should determine the type of trap installed.
