The stainless steel pickling production line usually uses a mixed acid solution of hydrofluoric acid and nitric acid, and uses traditional metal heat exchangers, which inevitably leads to acid leakage and contamination of the steel plates. Our Xinboao custom-made silicon carbide heat exchanger uses an integrated sintered silicon carbide tube inside, which not only avoids acid leakage but also significantly improves the yield rate of the steel plates.
