Determining a suitable fire protection bulkhead system depends on the size of the wall pipe and medium pipe as well as the movements to be accommodated, as listed in the following table.
| System | | Nominal diameter | Movement |
| | | |
| W200x + W200x |  | up to NB 400 wall pipes and NB 150 medium pipes | for axial and lateral movements |
| W200x + W400x |  | up to NB 750 wall pipes and NB 600 medium pipes | for small axial and lateral movements |
| W200x + W410x |  | up to NB 750 wall pipes and NB 600 medium pipes | for large axial and lateral movements |
Other nominal bore combinations possible.
The movements listed are based on a concentric position of the medium pipe in relation to the wall pipe
as well as minimal sectional medium pipe insulation thicknesses and a maximum ring gap of 100 mm.
Larger movements on request.
