Swivel joints are used wherever media pipes have to be moved. Articulated constructions with three swivel joints are used if linear displacements are necessary. If continuous rotary movements have to be realised, e.g. in round clarifiers, a swivel joints is arranged in the centre that connects the stationary pipe with the rotating scraper bar.
In many cases swivel joints can replace hoses when they reach their limits with regard to nominal width or excessive pressure or movement stresses. Hoses and swivel joints are also installed together, however, if the repetitive torsion and bending stresses cause breakages at the hose/fitting connections.
