Abstract

PURPOSE:To uniformize the thickness of the enamel-glass particle layer deposited on the outer periphery of a pipe and to obtain the title enameled pipe having high roundness by using a cylindrical electrode as the counter electrode in the electrophoretic coating method, arranging a metallic pipe almost at the center of the electrode, glazing, and then sintering the pipe. CONSTITUTION:The one end of the metallic pipe 5 is held by the chuck 7 of a holder 6, and the pipe 5 is dipped almost at the center of the cylindrical counter electrode 4 arranged in the slip S consisting essentially of enamel glass based on SiO2-PbO, etc., in a dipping tank 1. An agitator 2 is then rotated to agitate the slip S between the counter electrode 4 and the pipe 5, a DC voltage is impressed between the counter electrode 4 and the pipe 5, glass particles are uniformly deposited on the surface of the pipe 5 by electrophoretic coating to glaze the pipe, and then the pipe 5 is pulled up from the tank 1, dried, and sintered. By this method, the thickness of the enamel layer formed on the outer periphery of the pipe 5 is uniformized, and an enameled pipe having high roundness can be produced.
