Metal pall rings are usually made of metal materials such as stainless steel, carbon steel, and copper. These materials have excellent high temperature resistance and can maintain stable mechanical and chemical properties under high temperature environments.

Stainless steel: made of stainless steel such as 304 and 316L, which has good high-temperature resistance and corrosion resistance, can resist oxidation and corrosion at high temperatures, and is suitable for general high-temperature processes.

Carbon steel: Although it is corrosion resistance is not as good as stainless steel, it has higher strength and lower cost. It is suitable for occasions where corrosion resistance is not high but needs to withstand high temperature and high pressure.

Metal pall rings are widely used in high-temperature processes such as petroleum refining, coal chemical industry, fertilizer production, etc., such as:

Catalytic cracking device: In petroleum refining, the catalytic cracking device needs to react at high temperature. The metal bald ring can withstand the high temperature and the erosion of catalyst particles, while providing good gas-liquid contact to promote the reaction.

Synthetic ammonia converter: In the production of fertilizers, the synthetic ammonia converter needs to react under high temperature and high pressure. The metal pall ring can withstand high temperature and high pressure, and at the same time provide good mass transfer efficiency and improve the reaction conversion rate.

Performance advantages of metal pall rings

Excellent high temperature resistance: It can maintain stable mechanical and chemical properties in high temperature environments, reducing the risk of equipment deformation and failure.

Good high pressure resistance: Metal material has high mechanical strength and can withstand high pressure, and is suitable for high pressure processes.

Efficient mass transfer efficiency: The porosity and specific surface area of the metal pall ring are large, which can provide good gas-liquid contact, promote the mass transfer process, and improve separation efficiency.
