Glass LLined Reactor 50L 100L 500L

Glass lined reactor is made by lining the inner surface of a steel container with high-silica-containing glass, which is burned and firmly adhered to the metal surface to become a composite product. Therefore, it has the dual advantages of the stability of glass and the strength of metal, and is an excellent corrosion-resistant equipment.

Glass-lined reactors have two structures: separate type and closed type. The open type has a separate body and cover and is connected with a mat and a clip in the middle. Generally, the volume is less than 5000L; the closed type has an integrated body and cover, and the general volume is more than 5000L. Both structures have their own advantages. The open type is more convenient to disassemble. If there is a problem with the nozzle on the tank cover, it can be easily removed and repaired separately, while the closed type has better sealing performance. Generally speaking, there are two types of open structures: flat welding butt flange connection and flat cover type.

Glass-lined reactors are used in chemical, petroleum, food and other industries. In order to ensure the normal use of glass-lined equipment, its main performance and 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 acids, inorganic acids and solvents. For example, if a glass-lined sample is boiled in 20HCI solution for 48 hours, the corrosion rate is 0.9g/m2.d (the index of excellent products is 1.0g/m2.d).
3. Alkali resistance: Glass-lined glass has worse corrosion resistance to alkaline solutions than acidic solutions. However, the glass-lined sample was corroded in 1N H sodium oxide solution at a test temperature of 80°C for 48 hours. The corrosion rate is 6.76g/m2.d (the index of high-quality products is 7.0g/m2.d).
4. Operating temperature: When heating and cooling glass-lined equipment, it should be done slowly. The operating temperature of glass-lined equipment is 0-200℃, and the temperature resistance to rapid degeneration is ≥200℃.
5. Porcelain layer thickness: The porcelain layer thickness of glass equipment is 0.8-2.0mm, and the porcelain layer thickness of glass-lined equipment accessories is 0.6-1.8mm.
6. Withstand voltage and electricity: Glass lining has insulating properties. When the glass lining is used to check the porcelain layer with 20KV electric spark within the specified thickness, the electric spark cannot penetrate the porcelain layer.
7. Impact resistance: The smaller the internal stress of the glass layer, the better the elasticity, the greater the hardness, and the higher the strength, the better the impact. When the glass layer is within the specified thickness and is impacted by a steel ball with a diameter of 30mm and a weight of 112g, the impact energy is 282×10-3J (the index of high-quality products is 260×10-3J).
