FAQ
Frequently Asked Questions About 316L Porous Metal Discs
1. What are 316L porous metal discs used for?
316L porous metal discs are used for filtration, separation, flow control, and gas diffusion in various industries such as chemical processing, pharmaceuticals, food and beverage, and water treatment. Their excellent durability and resistance to corrosion make them ideal for high-performance filtration applications.
2. Why is 316L stainless steel preferred for porous metal discs?
316L stainless steel is preferred due to its superior resistance to corrosion, especially in harsh or corrosive environments. It also offers excellent durability, temperature resistance, and chemical compatibility, making it suitable for demanding industrial applications.
3. How do I choose the right pore size for my application?
The right pore size depends on your specific filtration needs. For fine filtration, smaller pore sizes (measured in microns) are used to capture smaller particles. For coarser filtration, larger pore sizes allow greater flow rates while still providing effective filtration. It's important to match pore size to the particle size you're filtering or the desired flow rate.
4. Are 316L porous metal discs suitable for high-temperature applications?
Yes, 316L porous metal discs can withstand high temperatures, up to 500°C (932°F) or more, depending on the application. This makes them ideal for industries requiring high thermal stability, such as chemical processing and gas filtration.
5. Can 316L porous metal discs be cleaned and reused?
Yes, they are designed for easy cleaning and reuse. Depending on the application, they can be cleaned using methods such as ultrasonic cleaning, chemical washing, backflushing, or air blowback. Regular cleaning helps extend the disc’s lifespan and maintain its filtration efficiency.
6. What customization options are available for 316L porous metal discs?
At HENGKO, we offer customization in terms of size, shape, thickness, pore size, and surface treatments. We can also modify designs based on specific requirements, ensuring optimal performance in your application.
7. How long do 316L porous metal discs last?
The lifespan depends on factors like the application, environment, and maintenance. With proper use and regular cleaning, 316L porous metal discs can last for several years, providing consistent performance in demanding conditions.
8. Are 316L porous metal discs resistant to chemicals?
Yes, 316L stainless steel offers excellent resistance to many chemicals, acids, and alkalis, making these discs suitable for use in aggressive chemical environments without corrosion or degradation.
9. Can 316L porous metal discs be used for gas and liquid filtration?
Yes, they are versatile and can be used for both gas and liquid filtration. The porous structure allows for efficient filtration of fine particles, whether in air, gas, or liquid media.
10. How are 316L porous metal discs manufactured?
316L porous metal discs are typically manufactured using powder metallurgy techniques such as sintering, where metal powders are pressed and heated to form a solid structure with interconnected pores. This process allows for precise control over pore size and distribution.
