Question: What are the main materials currently used for acid storage tanks?

Thread Content

I have a question for everyone here in Sichuan. My current requirements for salt and acid storage tanks are as follows: industrial-grade concentrated salt acid (37%), with a volume of around 1500 liters; either vertical or horizontal design is acceptable. The tank should be equipped with a level sensor, a pressure sensor, a one-way valve, a check valve, as well as inlet and outlet pipes for the concentrated salt acid； For indoor use, with a service life of over 20 years ； It’s best to be able to handle a bit of pressure. There are no specific requirements regarding the level of cost. In addition, there is also a tank for preparing dilute acid, with the following general requirements: Medium: industrial-grade concentrated acid (37%) and deionized water; volume of around 500 L; it can be vertical or horizontal in design; it is equipped with a pH meter, level sensors, pressure sensors, a one-way exhaust valve, a one-way intake valve, an inlet pipe for concentrated acid, an inlet pipe for deionized water, and an outlet pipe for dilute acid ； For indoor use, with a service life of over 20 years ； It’s best to be able to handle some pressure ； An agitator is installed on the top of the tank. (Is heat dissipation a consideration?) I checked some previous posts on the forum, which are mostly from a few years ago. There are several common materials used for salt and acid storage tanks, such as fiberglass, PVC, polypropylene, and carbon steel linings. What are the advantages and disadvantages of each of these materials? Are there any particularly outstanding materials available to choose from? Can the requirements be met in terms of processing and manufacturing? If any manufacturers are interested, they can send an email to zjqciae@163.com
