English term or phrase: pressure thrust
Expansion joints must absorb the pressure thrust can be very large and the displacement of forces ....

Pressure thrust Fp in kN

The pressure thrust is in lines with axial expansion joints

http://becht.com/blog/what-is-bellows-pressure-thrust

Pressure thrust is present in all pressurized piping systems. It is simply the gage pressure times the inside area of the pipe. It acts at changes in direction, such as elbows, and at changes in pipe cross section, such as reducers. Pressure thrust is normally carried as an axial load by the pipe. However, inclusion of a bellows expansion joint, which is not intended to carry such axial loads, removes the normal means of resisting the pressure thrust. Therefore, other means, such as pipe anchors and hardware on the bellows such as tie rods, is required to carry the pressure thrust load.

The pressure thrust is the gage pressure times the area within the mean diameter (Dm) of a metallic bellows expansion joint. It can be helpful in system design to understand where the forces actually occur. Some pipe stress software use the simplifying assumption in the analysis that the force acts at the bellows, but only part of the force actually acts at that location.
