Selection of Strong Acid and Alkali Valves
Acetic acid: Acetic acid is one of the most corrosive substances in organic acids. Ordinary steel can be severely corroded in various concentrations and temperatures of acetic acid. Stainless steel is an excellent material for resisting acetic acid. Aluminum containing 316 stainless steel is also suitable for high temperatures and dilute acetic acid vapor. For high-temperature, high concentration acetic acid or other corrosive media, high alloy stainless steel or fluoroplastic pumps can be selected.
Salt water/seawater: The corrosion rate of ordinary steel in chloroform, seawater, and brine is not too high. Usually, coatings must be used to protect various types of stainless steel. The uniform corrosion rate is also very low, but local corrosion may be caused by atmospheric ions, and it is usually better to use aluminum bronze or 316 stainless steel.
