| description | The invention discloses a technology for conducting simultaneous electric induction heat treatment on the inner wall and the outer wall of a butt joint welding joint of a plug valve. A plug valve bodyand a steel pipe are forged for high-alloy heat resisting steel, and the inner wall and the outer wall are subjected to electric induction heating simultaneously; intermediate-frequency induction heat treatment construction technology is adopted for the connecting welding joint of the P92 steel pipe and the F92 valve body, and the heating temperatures of the inner wall and the outer wall are different; and electric induction heating is conducted on the valve body by the outer wall, and an intermediate-frequency electric induction heating method is adopted for the steel pipe and the forged connecting welding joint. By means of the technology, the diathermancy and welding quality of the welding joint in the heat treatment process are ensured, the heat treatment quality is effectively improved, and overheat of a wel |
