What material is generally used for pressure components in acetic acid pressure vessels?

For the pressure-bearing components of acetic acid storage vessels, materials with good corrosion resistance are usually chosen. Zirconium is an option, but due to its high cost, it is not the most commonly used material. The specific grade of zirconium to be used must be determined based on operating conditions such as the concentration and temperature of acetic acid. Austenitic stainless steels can be used for acetic acid storage under certain conditions; for example, 304 or 316 stainless steels perform well at certain temperatures and concentrations, but stress corrosion cracking may occur under high concentration and high temperature conditions. Titanium and titanium alloys exhibit excellent corrosion resistance to acetic acid; therefore, the use of titanium equipment is feasible, especially for the storage and handling of high-purity or high-temperature acetic acid. However, the cost of titanium materials is also high. When selecting a material, it is necessary to take into comprehensive consideration factors such as the corrosivity of the medium, operating temperature and pressure, equipment cost, and expected service life. .

Check the temperature; stainless steel is suitable at room temperature

Is the acetic acid gassed or non-gassed, and what pressure can it withstand? For non-gas applications, titanium, Hastelloy, alloy 20, 316 can be used; for gas applications, bronze, 304, 316, and titanium are suitable.

Zirconium materials are widely used in the reproduction process of acetic acid. Heat exchange equipment, due to the pressure it is subjected to and the high temperatures involved, requires zirconium materials; currently, composite panel materials are more commonly used as they are much cheaper.
