Abstract

PURPOSE: To eveny activate the inside surface of the pipe and enable plating to be evenly performed by using NH4HF2, N2SiF6 and NH4F as pickling solution and connecting the pipes of the same quality as the abovementioned pipe to both ends of the pipe then performing pickling activation treatment in pretreating of the inside surface plating of the zicalloy pipe.
CONSTITUTION: In pretreatment of the inside surface plating of a zircalloy pipe 1 for atomic fuel covering the metal pipes 2, 2 composed of the zircalloy pipes of the same kind as that of the pipe 1 are connected respectively to both ends of the pipe 1 and the outside surfaces thereof are covered with plastic pipes 6, 3. Next, the pickling solution is circulated in the pipes 2 and 1 through the plastic pipe 3 by a circulating pump 4 from a vessel 5 which contains one or more kinds of NH4HF2, H2SiF6, NH4F, HF or HBF4 as the pickling solution, whereby the inside surface of the zicalloy pipe 1 is activated. This method enables the entire inside surface of the plated zircalloy pipe to be subjected to pickling activation treatment owing to the presence of the metal pipes 2, 2.
