Where can I buy high-silicon cast iron pipes?
Thread Content
Our factory wants to use high-silicon cast iron pipes to cool sulfur dioxide gas containing dilute sulfuric acid.
There are many manufacturers that produce cast iron pipes; here are a few companies you can contact: Zhongxin Foundry Co., Ltd. in Linyi City, Shandong Province: 0539-8501387, 13508995755; Linyi Jinyuan Chemical Foundry: 0539-8501866, 13792998800, 13953967905; Nanjing Minle Foundry Co., Ltd.: 025-86420585, 13813846148
Can it be used in dilute acids? What high concentration?
Cast iron pipes cannot be used in dilute acids; generally, concentrations above 90% allow the use of cast iron without issues, while for dilute acids plastic or lining materials are used
Does Nanjing Minle Foundry Co., Ltd. not produce high-silicon cast iron pipes? The concentration of dilute acid in our factory is around 40% to 50%.

Steel-reinforced plastic composite pipes can be used to transport dilute sulfuric acid; they are resistant to pressure and corrosion, and have a low overall cost.
