Mobile dilatations – due to load and overloading of static load capacity respectively overload in terms of cycles, damages occur (shearing, breakin off, leaking, banging ...). Mobile dilatations are, from the viewpoint of their use: aluminium dilatations, steel dilatations, stainless steel dilatations, composite dilatations (may or may not be hydroinsulating) from the viewpoint of their use.
When it exceeds the usage rate, e.g. if the load is set to 100 cycles and 1500 cycles are loaded, damage of dilatations will automatically occur due to excessive load caused by underdimensioning. It follows from the above that a solution is needed that should meet the new situation while taking into account the expectation of the development for 5-10 years (the load may again increase somewhat).
