A method for producing plastic tanks for liquids with a tapping valve, wherein the tank is produced from a tubular parison by blow molding, and wherein a holding flange or a threaded socket is formed on the tank. After the drain outlet of the tank has been cut out of the tank wall inside the holding flange or the threaded socket, the finished preassembled tapping valve is welded by its inlet socket to the holding flange or the threaded socket of the tank by a welding machine, during which the tank is centered and held in the welding machine by the holding flange or the threaded socket. |
