6.3 Mounting cladded flanges
• Use flange screws according to the number of flange holes.
• Tighten the screws with the required torque (see table).
• Retighten the screws after 24 hours or after the first temperature cycle.
• Depending on process pressure and process temperature check and retighten the
screws at regular intervals.
Usually, the PTFE flange cladding also serves as a seal between the nozzle and the
device flange.
