With hose braids, not only are braid diameter, length of lay and braid angle in a certain
natural relationship to each other, so are also the axial and tangential forces to be taken
up by the wires.

For single braids of metal corrugated hoses, the following formulae applies:

Application:                               Materials:
Exhaust hoses to DIN 14572 are used for    Galvanised steel with glass fibre seal
carrying away exhaust gas from portable    Hot-dip galvanised steel (1.0226):
fire pumps (DIN 14410), from fire briga-   DN 20 and above
de vehicles (DIN 14502 part 1) and from
power-generating aggregates (DIN 14685).   Operating temperature:
The hoses prevent operating personnel      400 °C
from being hampered by exhaust gases.

  in different lengths. Connection is done
  with a union nut.

      Compensation of parallel pipe offset / isolation of vibrations




  Besides the take-up and compensation of
  assembly inaccuracies, stripwound hose
  assemblies are suitable for isolation or
  absorption of vibrations. The many
  versions of stripwound hoses make it
  impossible to apply a standard formula.

  Witzenmann has calculation programs
  in which variables such as geometric
  shape, hose position, type of seal, etc.
  can be taken into account. We prefer to
  use the type FA exhaust hose of stainless
  steel described on page 153. Among
  other things, selection of the correct hose
  requires precise details on the free hose
  length SL, deflection and axial movement ;
  please refer to the following sketch.

Sealing is to be carried out with special care. The sealing materials are to be selected
according to the operating conditions. Only approved sealing materials must be applied
for sealing of threaded fasteners in drinking water and gas insulations.

Only high-quality threads are appropriate for high operating requirements.
