Is passivation required after repairing the synthesis tower?
Thread Content
Is it necessary to passivate the repaired area with a passivation paste after repairing the synthetic tower lining? How severe would the impact be if it weren’t passivated?
It should be better, right? If nothing is done, what will be the consequences? I don’t know the exact figures! ! !
It must be passivated; this is an important task that must be carried out after major repairs to the synthesis tower
It should be passivated as a whole; special passivation can also be applied to the areas that need maintenance, but overall passivation is still necessary. Otherwise, no one can take responsibility for that
Repair of small areas does not require TIG welding, as this process creates a passivating protective layer on the surface of the weld pool after welding. For larger areas, passivation is necessary; after all, repeated heating during repairs destroys the already formed passivating layer. Additionally, there is a high-temperature passivation process that occurs when the synthesis tower is heated, which is generally sufficient to meet the requirements.
Let’s see if there are any relevant standards and specifications; following those standards and specifications will ensure reliability.
If the device undergoes overall temperature-induced passivation before operation, local passivation is not required.
1. For the repair of small areas, TIG welding is not necessary, as it creates a passivating protective layer on the surface of the weld pool after welding. For larger areas, passivation treatment is required; after all, repeated heating during repairs damages the already formed passivating layer. Additionally, there is a high-temperature passivation process that occurs when the synthesis tower is heated, which is generally sufficient to meet the needs. 2. If the device undergoes overall heating passivation before operation, local passivation is not required.
May I ask about the overall passivation procedure (plan)?
What is local passivation? Special passivation? Overall passivation?
