  • connecting elements are longitudinally movably guided by the drum half and provided with at least one securing element.
  • the bolts are longitudinally movably guided by the drum half and provided with a securing element.
  • the bolt nuts are longitudinally movably guided by the drum halves and provided with a securing element.
  • a reliable connection of the drum halves even at high internal pressures acting is achieved in that a plurality of connecting elements are arranged in the form of rows.
  • Defined biases are provided by arranging the drum halves relative to each other at least in the region of brackets for the fasteners with a gap-like spacing.
  • the gap-like distance is sealed by a seal that can be designed like a ring.
  • a high-quality seal even with large acting pressures and high temperatures is achieved in that the seal is made of metal.
  • a simple mounting of a steel seal is provided by the fact that the seal is supported by at least one magnet.
