Seeking advice: What type of pipeline should be used for 70% acid concentration? ?
Thread Content
Which manufacturers produce pipes with diameters d=500, 600 mm? ?
What is the OP’s profession? Acid concentration? Silica glass pipes? But 500, 600 is not easy to achieve!
Please clarify the question, OP! Such as the type of medium, temperature, pressure, etc
For pipes with a diameter of d=500, 600 mm, rattan rubber is used
If the temperature is not high, it is best to use non-metallic pipes or pipes lined with metal
Glass with a steel lining should work; direct glass processing and handling are difficult
Sulfuric acid? 70% sulfuric acid requires 304 material
Since concentration requires heating, using 304 steel is not appropriate; instead, glass-lined tubes or F4-lined steel tubes should be used. Additionally, it seems appropriate to explore using such a large pipe diameter for concentration.
PTFE-lined pipes are used to ensure complete corrosion resistance; they are in stock
