Pipe stop can be very effective means of reducing nozzle loads caused by pipe thermal expansion. Pipe stops are frequently used and the figure below shows most common applications of the pipe stop.
Air in the piping system comes from three sources. First is a water itself, since the water contains approximately 2% air by volume. Second source of air is a mechanical equipment, and third source is a initial pipe filling when some of the air will be trapped at the high points. The presence of air can impact pipe operation and lead to many problems in a piping system.
In your standard piping support drawings, you might find standard pipe support shown on the figure below. Please note that the connection plate is fairly large and it is tighten with many bolts to the flange. This type of support cannot be used for every piping system and for all pipe size. So, let’s see where we can use this type of support.
