Engineering Risks & FAQ - **Caution**: - **Caution**: - **Caution**: ### Q: What materials are suitable for starch slurry orifice plates? **A**: Our orifice plates are available in Stainless Steel 316L for corrosion resistance, Hardened Tool Steel for durability, and Food-Grade Polypropylene for chemical compatibility in starch processing applications. ### Q: How do I select the correct orifice diameter for my starch slurry application? **A**: The orifice diameter should be selected based on your required flow rate (Cv value), slurry viscosity, and system pressure. Our technical team can help you calculate the optimal diameter for your specific starch processing line. ### Q: What maintenance is required for starch slurry orifice plates? **A**: Regular inspection for wear, cleaning to prevent starch buildup, and gasket replacement are recommended. The low surface roughness (specified in μm) minimizes particle adhesion and simplifies maintenance in grain processing environments. ## 6.
