Abstract (en)
[origin: EP0745812A2] The one inner compartment contains a gas blanket, and the other inner compartment is connected by at least one connecting pipe (14, 16) positioned on the tank's wall to a water-conducting unit. The connecting pipe is shaped out of the material of the tank wall, and is in the form of a centering holder for the inserted connecting part. The connecting pipe has a thread. The annular rim of the connecting pipe is slightly widened outwards.
