What kind of heat exchanger can be acid and alkali resistant to high temperature

There is a kind of high temperature heat exchanger, you can ask manufacturers to ask, let them help you design, with different materials can meet your requirements

Who knows what kind of heat exchanger can be acid and alkali resistant to high temperature, the production of heat exchanger manufacturers can come out to help answer it? Thank you
A device for high temperature resistant materials. Xie better quality durable corrosion resistance to strong acid and alkali resistant.
1 titanium alloy materials can be selected.
2 steel lining fluorine corrosion. Corrosion resistant temperature and moderate price. A lower titanium alloy material
