I would like to ask about the corrosion resistance of slurry pump materials A33 and polyurethane
Thread Content
Is there anyone who knows something about the materials used in slurry pumps? What are the advantages and disadvantages of A33 material? What is the lowest pH value it can tolerate? What is its temperature range of operation? What are the pH and temperature ranges for polyurethanes?
In our coal chemical industry, CD4MCu is used as it is quite wear-resistant; if both wear resistance and corrosion resistance are required, then better materials such as duplex steel should be chosen. You can provide the specific process parameters
A33 is equivalent to Q235; if it is used in conditions where the pH value is below 7, it is likely not to resist corrosion, unless it is dealing with concentrated sulfuric acid.
Slurry pump material: Components in contact with the medium, such as the impeller and pump casing, can be made of 06CR13NI4MO.
A33 is wear and corrosion resistant; it is a material developed by Shijiazhuang Water Pump Factory
