Claims

[Scope of utility model registration request]

A heat-resistant and acid-resistant sleeve with a slit at the tip and a groove at the rear end and a thread formed on the outer surface is fitted with a backing into the groove to seal the gap between the heat exchanger tube and the heat exchanger tube sheet. At the same time, on the outer periphery of the sleeve, a push plate having a female thread on the inside and a groove at the tip is installed by fitting a gasket into the groove so that the groove comes into contact with the tube plate. A sealing portion of a heat exchange tube sheet, characterized in that the presser plate is screwed into a sleeve and sealed.
