Frequently Asked Questions
1. What is the difference between a Johnson screen and a standard wedge wire screen?
Johnson screens are a type of wedge wire screen with a continuous slot profile, offering superior strength and self-cleaning properties. They are commonly used in high-pressure applications.
2. Can the slot width be customized for my specific application?
Yes, we offer custom slot widths from 0.1mm to 10mm. Please provide your requirements for a tailored solution.
3. Is the 304 stainless steel suitable for saltwater environments?
304 stainless steel has good corrosion resistance but may be susceptible to pitting in high-chloride environments. For marine applications, we recommend 316L stainless steel.
4. What is the maximum operating temperature?
304 stainless steel can withstand temperatures up to 870°C (1600°F) in continuous service, but the actual limit depends on the application and pressure.
5. How do I clean the screen if it gets clogged?
Backwashing with water or air is effective. The wedge wire design minimizes clogging, but chemical cleaning may be used for stubborn deposits.
6. What lengths and diameters are available?
Standard lengths range from 100mm to 3000mm, with diameters up to 500mm. Custom sizes are available upon request.
7. Do you provide samples before bulk order?
Yes, we offer sample screens for testing. Please contact our sales team to discuss sample lead time and cost.
8. What is the lead time for a standard order of 500mm screens?
Typically 7-15 working days, depending on quantity. Expedited shipping is available upon request.
