Zirconium equipment
Thread Content
The zirconium material reactor vessel (zirconium-steel composite plate) developed small holes on its surface after one month of use
It may be due to erosion (abrasion), or surface defects (present before operation).
Wrong material selection: Perhaps the impact of impurities was not taken into account； The quality of the zirconium material is substandard, or the grade is incorrect. In short, having it in this state after just one month is extremely serious; there should at least be experimental evidence to serve as a basis for production. It seems that this device is a key piece of equipment on the production line, as it can cause the normal operation of the line to come to a halt.
It is clearly caused by corrosion; it is necessary to consider whether the material selection is appropriate and whether there are issues with the quality of the zirconium material.
Is zirconium steel explosive cladding plate being used? There are no welds here either; it’s probably related to the quality of the zirconium plate. Ultrasonic testing is required before leaving the factory.
Excluding factors such as the medium and operating conditions, there are three other possible causes for this situation: first, surface damage may occur after an explosion. Second, surface damage during the rolling process or manufacturing process ； Third, pickling and passivation are not very effective.
Apply the board quickly; otherwise, it will corrode and get damaged over time.
