【Abstract】 In use of titanium and zirconium clad plate as the material for the shell of tubular heat exchanger, some difficult issues in manufacture should be treated, such as that the strip for two materials welding makes assembly of tube bundle difficult. In this article, several methods with respect to the issue were presented, including reduction of baffle diameter, design of specific structure of clad plate welding strip and related fabricating process. It was hoped what presented herein may be referenced in the design and manufacture of the heat exchangers using similar materials.更多还原
