Background
Metals such as tantalum, zirconium, titanium and the like have good chemical stability, and the metal tantalum is not sensitive to the notch, so that the main corrosion mode is uniform corrosion, and local corrosion such as corrosion fatigue, corrosion cracking and the like is not easy to occur. Because of the above advantages, it has been increasingly applied to the sulfuric acid industry in recent years, among which tantalum-zirconium-lined pressure vessels are more prevalent.
In the manufacturing process, some penetrating defects are easy to miss detection due to the fact that a nondestructive detection method is lacked for welding defects of the tantalum layer. During the use of the equipment, the corrosion penetrability defect can occur due to the fact that materials such as tantalum, zirconium and the like are thin. In addition, because of different thermal expansion coefficients of steel and tantalum, the welding seam of the tantalum lining layer is easy to crack under the influence of temperature difference stress, and the like, which causes medium outflow, and destructive influence on the steel base layer without corrosion resistance, the corrosion area and the corrosion degree can not be directly observed, if corrosion leakage is not found in time, serious consequences can be caused.
In order to solve the problems of welding seam quality during manufacturing and medium leakage caused by corrosion penetration in the using process, whether a container leaks or not is generally judged by arranging a plurality of leakage detecting structures. Because the gasket channel is generally in a through state, leakage at any one position can cause medium to flow out of a plurality of leakage detecting nozzles on the container, and the specific position of the leakage cannot be determined.
