Expansion Joints

Metal expansion joints are also called "metal corrugated compensators", which
are composed of one or several bellows and metal components, which are used to
absorb the dimensional changes of pipes and (or) equipment caused by thermal
expansion and contraction.
The role of Corrugated Expansion Joints:
1. Compensation for thermal displacement. Absorb the elongation or shortening
displacement of the pipeline due to temperature changes, ensure the constant
distance between the two fixed supports and release the temperature stress, so
that the pipeline can operate safely.
2. Shock absorption and noise reduction. When the equipment vibrates, the
expansion joint installed between the equipment and the pipeline is equivalent
to a closed spring, which isolates the transmission of equipment vibration to
the pipeline and reduces structural vibration and noise.
3. Protect the equipment. The installation of corrugated expansion joints at
the inlet and outlet of equipment with strict requirements on forces can
effectively reduce the force of the pipeline on the inlet and outlet of the
equipment.
4. Improve the tightness of the flange connection. Effectively reduce the
stress of flange connecting bolts and improve sealing performance.
