Motion limiters

protect the compensator against exceeding the allowable (maximum) compensation values ​​caused by equipment vibrations or pipeline stresses.
Vacuum rings

they are used in expansion joints working under negative pressure and are used to protect the rubber bellows expansion joints against collapse. The rings are flooded in the compensator bellows permanently, so they do not come into contact with the flowing medium. For the production of rings, an acid-resistant steel rod grade 1.4301 with a diameter of Ø2 - Ø20mm is used.
Protective cover

serves to mitigate the effects of possible damage to the expansion joint by stopping the leakage of medium directly into the environment.
