What is the significance of choosing glass-lined equipment?
Thread Content
As is well known, glass-lined equipment is made by applying a layer of glass glaze powder to the surface of steel and then firing it at high temperatures. Glass is brittle, and the different coefficients of thermal expansion between glass and steel mean that glass-lined equipment is particularly vulnerable to thermal shock and mechanical impact. Inexperienced users and suppliers with lax quality control can cause a lot of problems in later use... So I wonder, why do so many companies still choose to use enamel? What are the reasons behind that?
Equipment made of glass-lined material is chosen primarily due to the high corrosivity of the process media, such as sulfuric acid and nitric acid
I have encountered clients who use enamel for the kettle body and stainless steel for the stirrer
Perhaps it is the reuse of old equipment; the corrosivity of the process is not very high, so both enamel and stainless steel can be used.
