As the title suggests: materials that can withstand both dilute sulfuric acid and dilute alkaline media? This post was last edited by zzg5680 on 2009-2-4 at 12:44

It depends on the specific technical specifications of this device. Please share the detailed parameters, and we’ll help you out, okay?

Horizontal tank with a capacity of 50 m3, at atmospheric pressure; the waste liquid contains 10% alkali, and it is neutralized using 98% sulfuric acid – there is a possibility that too much acid will be used.

We use PP plastic: victory: :victory:

In China, non-metallic materials such as plastics like PP, PE, and PVC are generally used. If one has plenty of money, non-ferrous metals such as AL-6XN can also be employed

Materials that can withstand dilute sulfuric acid and alkalis include the PP, PE, and PVC mentioned above; however, these materials tend to age easily, and replacing them becomes inconvenient over time. PTFE can be used in such cases – although its price is relatively high, it has excellent resistance to acids and alkalis and is durable. If it is easy to replace and the usage amount is low, it is also acceptable to use the three materials mentioned above; just replace it once a year.

Acid- and alkali-resistant fiberglass can also be used when the temperature does not exceed 60 degrees.

Super stainless steels like AL-6XN are indeed excellent

Fiberglass containers should work. .

Pipes can be made of HDFE material, and heat fusion welding can be used; the equipment can have an inner lining made of engineering plastic, with PE tape wrapped around it, allowing it to remain in good condition for many years. The company in Shanghai owned by the French company Arabelle seems to produce such equipment!
