Frequently Asked Questions
1. What is the maximum operating temperature for this filter?
316L stainless steel can typically withstand temperatures up to 450°C in continuous service, but the actual limit depends on the sealing materials and pressure. For high-temperature applications, please consult our engineering team.
2. Can the slot width be customized to a different size?
Yes, we offer slot widths from 0.1 mm to 6 mm. Custom sizes are available with minimum order quantities. Please specify your exact requirement.
3. Does this filter come with end flanges installed?
We can supply the filter with or without end connections. Flanges, threaded ends, or other custom connections are available upon request. Standard options include ANSI/DIN flanges.
4. How is the filter cleaned?
The wedge wire design allows for efficient backwashing. For pressure vessel applications, the filter can be cleaned by reverse flow or chemical cleaning. The smooth surface resists fouling.
5. What is the typical lead time for this product?
For standard specifications (0.2 mm slot, 1800 mm length), lead time is approximately 15-20 working days. Custom orders may require 25-30 working days depending on complexity.
6. Can you provide material certificates?
Yes, we can provide mill test certificates for the 316L stainless steel material upon request. Additional third-party inspection is also possible.
7. What is the minimum order quantity?
Our standard MOQ is 10 pieces for this size. For volume orders, we can offer competitive pricing and faster delivery.
8. Is this filter suitable for seawater applications?
316L stainless steel offers good resistance to chloride-induced corrosion, making it suitable for seawater and brackish water environments. For extremely harsh conditions, we recommend proper material selection – please contact us for advice.
