What are the common faults and maintenance methods of stainless steel reaction tanks?

Stainless steel reaction tanks are vital in a variety of industrial processes, but stainless steel reaction tanks can experience some common problems that require attention and maintenance. Here are some of the most common problems and how to fix them:

1.  Reactor scaling  : This refers to the accumulation of unwanted substances on the walls and surfaces of the stainless steel reactor tank, which reduces heat transfer efficiency and increases pressure drop. To combat this, preventive measures include the use of anti-fouling coatings and chemical additives to inhibit sediment formation. Cleaning methods include chemical cleaning with solvents or acids to dissolve deposits, as well as mechanical cleaning such as scraping or hydraulic spraying.

2.  Catalyst deactivation  : Over time, the catalyst will lose its activity due to sintering, poisoning, coking and thermal degradation. Regular catalyst regeneration is necessary to maintain the performance of the stainless steel reactor tanks This can involve processes such as burning carbon deposits or using chemicals to remove poisons.

3.  Corrosion and pitting  : Stainless steel can be corroded by exposure to corrosive chemicals or environments. Regular inspection and maintenance is essential to detect and repair corrosion before it causes more serious damage. Repair methods may include sanding the pits and applying a protective coating.

4.  Stress corrosion cracking (SCC) : This occurs due to the combined action of mechanical stress and the corrosive environment. SCC management includes limiting residual strain and preventing oxygen from entering the supply water by optimizing manufacturing procedures.

5.  Corrosion  : This is caused by hard particles hitting the reactor surface in the corrosive environment. Repair methods include replacing or modifying affected parts to reduce particle impact and applying more durable materials or coatings.

In summary, regular monitoring, maintenance and timely repairs are essential to prevent these common problems from interfering with the operation of stainless steel reactor tanks.
