The minimum wall thickness for the S transfer tube depends on the
maximum possible operating pressure. Furthermore, the fact that the
S transfer tube is subject to greater stress at the point at which the
torque is applied (switching shaft
− S transfer tube) must be taken
into consideration.

Note
We should draw your attention to the fact that the S transfer tube is
subject to varying loading as a result of the dynamic loading during
pumping. There is no general method for calculating the minimum
wall thickness for this loading, which depends on the individual cir
cumstances, and so the S transfer tube can also burst at an operat
ing pressure which is assumed still to be permissible.
You should also note that the operating pressure can rise to the
maximum pressure in the event of a blockage, and in this case the
wall thickness may no longer be adequate.
If the operating pressure is higher than 130bar, you must ask
Putzmeister what the minimum wall thickness is.
