Regarding the maximum operating temperature of glass-lined equipment
Thread Content
background: Last year, I met a customer in Shandong. The working temperature was 250°C (maybe higher). The enamel reactor used on site was of an impeller type. Porcelain explosions often occurred at the end of the agitator. The reactor had a bottom air intake process, and the materials inside were hydrogen chloride and chlorine. discuss: 1) What is the reason for the damage to the equipment agitator? 2) What is the maximum operating temperature of glass-lined equipment and what factors are related to it?
This is standard, because the corrosion of materials by media is generally a non-linear curve related to concentration and temperature. But what if the medium is very corrosive to enamel? For example, if I use enamel for its smooth surface and easy cleaning, instead of its anti-corrosion effect, what temperature can be used in this case?
No, the highest temperature I have encountered is 210. If the temperature is higher, the gasket will not work well. Glass-lined gaskets are all non-metallic. To achieve sealing under high temperature and pressure, relatively large bolt force must be applied. The gasket area softens under high temperature. One pressure can be exaggeratedly understood as squeezing toothpaste.
