The shock absorber sleeves function as expansion joints.

 

They are structured to absorb the vibration of the pipe. Normally they are installed in the suction or in the pumps.

They have a reduced cost in comparison with the joints of greater diameter.

 

The flow section is completely free, which is a great advantage since it avoids turbulence and transmission of vibrations to the line.
