  • SWIVEL JOINT PIPE SYSTEMS ARE USED WHEN PIPES MUST PERFORM SWIVELLING OR ROTATING MOVEMENTS AGAINST EACH OTHER.
  • BY MEANS OF A SUITABLE SELECTION OF SWIVEL JOINT TYPES NEARLY ALL MOVEMENTS ARE POSSIBLE.
  • SWIVEL JOINT PIPE SYSTEMS ARE OFTEN USED AS SUBSTITUTES FOR HOSE SYSTEMS, ESPECIALLY WHEN THE OPERATIONAL SAFETY OF PLANTS IS ENDANGERED BY EXTERNAL STRESSES ( TORSION, BENDING FORCES ) WHICH AFFECT THE HOSES.
  • IN MOST CASES THE FAILURE OF A HOSE HAPPENS ABRUPTLY AND CAN CAUSE GREAT DAMAGES.
  • BY MEANS OF A SUITABLE SELECTION OF SWIVEL JOINT TYPES NEARLY ALL MOVEMENTS ARE POSSIBLE.
