For sectional medium pipe insulation, the required length (L) needs to be based on the neutral fiber of the medium pipe. The pipe clamp should be fitted outside the pipeline elbow (distance III). The thickness of the insulation should be taken into account when laying the pipeline (distance II). For large axial movements, the installation length of the membrane or expansion joint needs to be at least 300 mm in order to accommodate movements. 

If the construction site conditions do not allow for the installation of standardized structural forms, application-specific fire protection bulkheads can be manufactured. The clamping area can also be located in the elbow radius for these.
