される。. Conventionally, when explosive crimping a tube or plug and a tube sheet,
The type and amount of explosives are adjusted according to the wall thickness and inner diameter of the tube or plug, and the detonation is carried out using an all-electric detonator. This method requires a certain amount of explosives to be used, and if the amount of explosives is large, it has the drawback of adversely affecting adjacent tube plate holes, such as deforming them. In order to solve this problem, the present applicant made the invention described in Japanese Patent Application No. 55-36189. In this invention, in the case, the bottom part has a thickness of 3.
