Acid-generating dry absorption pipeline
Thread Content
What are the different types of main circulation pipelines for acid-generating dry absorption? Are there pipes lined with steel and PTFE in large installations? Thank you all for your advice
Useful materials include cast iron pipes, anodically protected stainless steel, and high-silicon stainless steel; steel-lined PTFE is less common.
Hehe, rare---what does that mean? Could you give an example? We all know that the options for pipes generally include: cast iron pipes, imported 316L or 316L with a protective coating, and alloy pipes such as SX alloy, XD alloy, HD alloy, etc. But do domestic large-scale sulfuric acid production plants (with a capacity of over 400,000 units) also use pipes lined with steel and Teflon?
