泡液に係り、被検体を腐蝕。[Detailed Description of the Invention] The present invention is used in a method of applying a foaming liquid to valves, pipe connections, etc. of city gas, pressurized gas, etc. and inspecting for gas leakage by checking the presence or absence of foaming. The foaming liquid for gas leak testing corrodes the test object.

にする。However, since soapy water contains inorganic salts such as mirabilite, when dried after the test, the inorganic salts remain as white adherents on the surface of the test object such as valves, damaging the appearance of the test object and corroding the test object. In severe cases, the opening and closing functions of the valve become difficult due to the inorganic salts that accumulate with each inspection and the progress of corrosion.
又石鹸水はガス漏洩検査用起泡液として十分な泡の発泡
