Materials, mixing devices, heating methods, shaft seal structures, volume sizes, temperatures, pressures, and more vary among different reactors, each with numerous types. The basic characteristics are described as follows: Reactor
 

I. Structure

The reactor structure is essentially the same, with the reactor body, transmission device, agitation, and heating (or cooling) equipment, which can improve heat transfer conditions, resulting in more uniform temperature control of the reaction and not enhancing the mass transfer process.

Tanks, as the name implies, are containers made by welding. Generally, tanks should have high sealing integrity and excellent corrosion resistance, which places high demands on the manufacturing technology and welding techniques. So, what are the welding techniques for tanks? Let's find out together below.

Welding techniques are numerous, and each one yields satisfactory quality. However, when manufacturing storage tanks, the most commonly used method is TIG welding, typically performed manually. In TIG welding, we employ low current, rapid welding speed, and short arc narrow groove welding, ensuring that the interlayer temperature is kept below 100 degrees. Of course, the welding material must also be appropriately matched, as failure to do so can compromise the welding results.

Operational Pressure

The operation pressure of reaction kettles is relatively high. The pressure inside the kettle is either generated by chemical reactions or formed by increased temperature, with significant fluctuations. Sometimes, the operation may be unstable, and a sudden increase in pressure can exceed the normal pressure several times over. Therefore, most reaction kettles are classified as pressure vessels.
