INSTALLATION OF MULTITUBE FIREPROOF INTUMESCENT TAPE ON A METAL PIPE WITH FEF FOAM INSULATION PENETRATING WALL OR FLOOR

Read from  the Table below for steel pipes,  for copper pipes or for cast iron pipes, the length of the Multitube fireproof tape for the given pipe diameter, measure it and cut it off
with a knife

Wrap the cut piece of fireproof tape around the pipe insulation. Adhere strictly to the number of coils given in Table 11.1 for steel pipes, 11.2 for copper pipes or 11.3 for cast iron pipes.
Secure the tape with an electrically clamped band and slide it into the partition. Location of the tape inside the opening - central position along the wall axis or 10-15 mm from the bottom of the floor
Fill the space between the pipe and the partition with cement mortar

Mark the completed penetration seal with the attached label, mark the Multitube fireproof tape on it, enter the date and
name
