Second hand enamel reaction kettle with high temperature resistance

The second-hand enamel reaction kettle is a composite material product made by lining high silica glass on the inner surface of a steel container, and firmly adhering it to the metal surface through high-temperature burning. So, it has the dual advantages of glass stability and metal strength, making it an excellent corrosion-resistant equipment

Enamel reaction kettle, with two types of structures: separated and closed. The open type has a separate body and lid, connected by a cushion and clip in the middle. Generally, it has a capacity of less than 5000L; Closed type with integrated body and cover, generally with a capacity of over 5000L. These two structures each have their own advantages. Open disassembly is more convenient, and if there is a problem with the pipe opening on the can cover, it is easy to remove and repair separately. Closed disassembly has better sealing performance. Generally speaking, there are two types of open structures: flat welding butt flange connection and flat cover connection

Application instructions for second-hand enamel reaction kettle

Glass lined reaction vessels are widely used in industries such as chemical, petroleum, pesticide, and food. In order to ensure the normal use of glass lining equipment, the main performance, installation, and usage precautions are described as follows:

1. Operating pressure: 0.2-0.4Mpa

2. Acid resistance: It has good corrosion resistance to various organic acids, inorganic acids, and organic solvents. If the enamel glass sample is boiled in a 20% HCl solution for 48 hours, the corrosion rate is 0.9g/m2. d (the premium product index is 1.0g/m2. d).

3. Alkali resistance: Glass lining has poorer corrosion resistance to alkaline solutions than acidic solutions. But the enamel glass sample was placed in a 1N sodium hydroxide solution for corrosion, with a test temperature of 80 ℃ for 48 hours. The corrosion rate was 6.76g/m2. d (the premium product index was 7.0g/m2. d).

4. Operating temperature: When heating and cooling glass lined equipment, it should be done slowly. The operating temperature of the enamel glass equipment is 0-200 ℃, and its resistance to sudden temperature changes is ≥ 200 ℃.

5. Ceramic layer thickness: The ceramic layer thickness of glass equipment is 0.8-2.0mm, and the ceramic layer thickness of enamel equipment accessories is 0.6-1.8mm.

6. Voltage resistance: Glass lined insulation has good insulation properties. When using a 20KV high-frequency electric spark to inspect the porcelain layer within the specified thickness, the high-frequency electric spark cannot penetrate the porcelain layer.

7. Impact resistance: The lower the internal stress of the glass layer, the better the elasticity, the greater the hardness, and the higher the bending and compressive strength, the better the impact resistance. When the glass layer is impacted by a steel ball with a diameter of 30mm and a weight of 112g within the specified thickness, its impact energy is 282 × 10-3J (the superior product index is 260 × 10-3J)
