さいだ。Example 2: Figure 2 shows an example of flue repair. The flue pipe 1 is made of titanium, and welding is difficult and takes a long time, so a carbon steel patch plate 2 is applied to the repaired part 3 with an inorganic composition 4 to close the corrosion hole in the flue.

The flue 1 is made of carbon steel and has an FRP lining 2 installed on its inner surface, but due to deterioration of the FRP lining 2, the flue 1 itself was damaged, so a new flue 1, which was finned on site, was connected by welding. This is an example in which the area around the welded portion 3 was repaired using the inorganic composition 4 described above.
