Title:
タンク耐圧試験時のタンク腐食防止方法
Document Type and Number:
Japanese Patent JP6460493
Kind Code:
B2
Abstract:
An inner surface of a tank 10 is formed by joining a large number of metal plates 21, 23 and 25 to one another by welding. Before injecting pressure resistance testing water into an inside of the tank 10 in order to test pressure resistance of the tank 10, a corrosion inhibitor 31 is applied to welds 27 between the metal plates 21, 23 and 25 on a bottom part of the tank 10. A total bottom part area A1 of the welds 27 to be applied with the corrosion inhibitor 31 on the bottom part of the tank 10 is made wider than a total non-bottom-part area A2 of the welds to be applied with the corrosion inhibitor 31 on the inner surface of the tank 10 other than the bottom part of the tank 10.
