である。However, despite careful selection of lining materials and welding rods, strict inspections, and careful welding work by skilled welding engineers, leakage accidents still occur, as shown in Figure 2. In this way, a detection hole 10 is provided near the lining weld 9 to detect leakage at an early stage and perform emergency repairs. The damage caused by the outage is extremely large. The present invention has been proposed in order to eliminate such drawbacks, and the present invention has been proposed in which the inner cylinder disposed inside the multilayer part of the body of the multilayer pressure vessel is made of clad steel made of carbon steel and corrosion-resistant material. This invention relates to a multilayer pressure vessel characterized in that a lining layer made of a corrosion-resistant material is layered inside the corrosion-resistant material layer in the inner cylinder.

金の廃止によってラィニング作業も容易になる。As described above, in the multilayer pressure vessel according to the present invention,
The cylindrical tube disposed on the multi-layer inner side of the fuselage is made of clad steel made of carbon steel and corrosion-resistant material, and a lining layer made of a corrosion-resistant material is layered inside the corrosion-resistant material layer of the inner tube. Therefore, even if a corrosive substance leaks from the lining layer or lining weld, the corrosion-resistant material layer of the clad steel that makes up the inner cylinder will prevent the leakage to the carbon steel part and prevent corrosion. This not only significantly improves safety against corrosive substances, but also facilitates lining work by eliminating the use of backing metal.
