What is this protrusion?

What is its function? What kind of equipment is needed?
Its scientific name should be “pipe compensator,” and it is primarily used to counteract the transmission of vibrations and to compensate for stresses in pipes. For reference.
The expansion joints of heat exchangers serve to buffer the thermal expansion and contraction stresses in both the tube side and shell side. Whether to design expansion joints depends on whether the expansion stresses in the tube side and shell side exceed the allowable stress of the material, and this must be determined through calculations. This is necessary when there is a large temperature difference between the inside and outside, when the equipment is long, or when there are significant differences in the thermal expansion coefficients of the materials used on the inside and outside. The most important thing is to determine it by calculating stress.
This shouldn’t be a heat exchanger; although it’s a partial area, it’s most likely a pipe!
It’s most likely a heat exchanger; pipe expansion joints are rarely made in this shape

Sorry, you win! :handshake
Stress-compensated, with large temperature differences
