LINING METHOD FOR CLAD NOZZLE

摘要

PURPOSE:To simplify a nozzle fitting by forming a thin wall part at the tip of a nozzle, welding the base metal of a tank main body and the nozzle each other as well, then after calking the thin wall part to the tank main body welding a corrosion resistant cover to the connection part thereof. CONSTITUTION:A thin wall part 7 is formed by cutting the tip of the fitting part of a clad nozzle 1, then, the base metals of the nozzle 1 and tank main body 2 are welded together with a patch 5. The thin part 7 of nozzle 1 is subjected to a calking along the curved face part 8 to the tank main body 2 side and a filler plate 3 is inserted between the thin part 7 and tank main body 2 tip. Finally the cover 4 of a corrosion resistant material covering this connection part is welded. In this way the need of welding by preparing a bell mouth cover is eliminated and the clad nozzle fitting work is simplified.
