Abstract

PURPOSE: To reduce electrolytic corrosion of tube plate material by meltingly infusing metal showing inferior potential as sacrifice anode over a tubular part material.
CONSTITUTION: After meltingly infusing a metal showing inferior potential, such as Zn or Al over the surface corresponding to a tubular part material 1, a tubular material 3 is inserted before expanding. Otherwise, after the tubular part material 1 is expandingly fixed or sealingly welded with the tubelar material 3 and after the tubular extremity is recovered with a cap 5, etc., inferior metal is infused in melting condition, and succeedingly to the completion of melting infusion, the cap 5 is taken out. Besides, it is desirable to seal up bores produced by the melting infusion over the melting infused layer 4 with use of proper resin.
