The long neck flange is used to connect piping arrangements where the lap joint is applied. Generally, the component can be manufactured by welding, but this method is both time and cost intensive. Embrittlement at the heat affected zones was also considered. A spinning method developed to improve the manufacturing process and solve the problems of welding. The flange area of the long neck flange can be formed by changing the direction of the metal flow, from axial to radial, while maintaining pressure by using an outer mold and a lap roller. A modified process was additionally developed using a round roller rather than the outer mold. In this modification, the round roller can form the shape of all sizes of long neck flange. Using these flexible methodologies, the cost to prepare outer molds and the time to install and remove the molds can be significantly reduced.

Radiators are used in order to prevent temperature rise of the transformer core and windings. This study has performed to analyze Radiator Support Structure about dead and seismic loading condition. At the connection area between radiator flange part and Tank flange Part, the shear, tension and von-mises stress in the connected bolt shall not exceed allowable stress. This paper shows that the structural strength has been improved by applying the reinforcement band on the radiator.
