Analysis of advantages and disadvantages of stainless steel reactor and glass lined reactor

What are the inherent advantages and disadvantages of the two kinds of kettles in use:

For example, the stainless steel reactor is not applicable to the acid reaction system, while the glass lined reactor has large heat transfer resistance and high energy consumption

What are the inherent advantages and disadvantages of the two kinds of kettles in use:

The inner surface of glass lined reactor has a higher finish than that of stainless steel reactor. It is better for some materials with high viscosity: the common point is that they are clean.

Difference: stainless steel is alkali resistant, and enamel is acid resistant.

It is easy to repair the broken stainless steel, and difficult to repair the broken enamel.

The surface of enamel is hard and ultra-low temperature. Generally, stainless steel is used instead of enamel

If the material has no corrosion to stainless steel, the stainless steel kettle is good

1. Where both are applicable, glass lining is generally preferred, because glass lining kettle is cheaper.

2. In general, glass lined reaction kettle has poor alkali resistance, while stainless steel reaction kettle has poor acid resistance, but it is not absolute. For example, 316L can resist nitric acid.

3. Glass lined reactor has poor pressure resistance, while stainless steel reactor is easy to achieve higher pressure.

4. The stainless steel reaction kettle is easy to repair when it is damaged, while the glass lined reaction kettle is difficult to repair, and it is easier to explode porcelain when it is hoisted, welded, the temperature changes sharply or hit.

5. Generally, heat transfer effect is not the main consideration.

The equipment shall be selected mainly according to the performance of the product. Enamel and stainless steel have their own characteristics. Stainless steel shall be used as much as possible when stainless steel can be used. It is convenient in installation, maintenance, heating and cooling.

1. The medium in the stainless steel reactor must not contain chloride ions, even a small amount;

2. Due to the high temperature during welding, the chromium and carbon at the grain boundary are combined, and the chromium content at the grain boundary is reduced to form a chromium poor zone,

Therefore, a “chromium carbide (cathode) – chromium poor area (anode)” battery is formed in a suitable corrosion solution to cause corrosion in the chromium poor area at the grain boundary. Choose according to different situations.
