Problems with tapered pipes
Thread Content
May I ask, what are the differences between these two types of pipe designs? Is the one that is smaller at both ends and larger in the middle better than one with a diameter of 1 inch?
Pressure generally does not require diameter changes, while temperature does. Because the temperature sensor needs to be inserted inside the pipe.

This is determined based on the selection of the pressure gauge; if a DN40 pressure gauge (such as a diaphragm pressure gauge) is used for a DN25 main pipe, it is necessary to use a reducer for the smaller diameter, but there is no requirement regarding the length of the reducer.
Could it be related to the process requirements? The diameter has changed; it functions as a small buffer tank
