Key Features & Technical Specifications
- Material Excellence: 316L stainless steel (low carbon) offers superior resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride-rich chemical environments.
- Precision Slot Design: Vee-wire (Johnson wedge) profile provides a continuous slot opening from 0.1mm to 5mm, ensuring uniform filtration and easy backwashing.
- High Open Area: The wedge wire structure maximizes open area, enabling high flow rates while maintaining particle retention.
- Mechanical Strength: Robust welded construction withstands high pressure, vibration, and thermal cycling typical in chemical processing plants.
- Customizable Dimensions: Available in various diameters, lengths, and end connections (flange, threaded, plain) to fit your existing equipment.
- Surface Finish: Standard pickling and passivation removes weld oxide and enhances corrosion resistance; additional polishing available upon request.
- Compatibility: Suitable for use in reactors, columns, filters, strainers, and water treatment systems.

Frequently Asked Questions
-
Q: What is the difference between 316L and 304 stainless steel for chemical processing?
A: 316L contains molybdenum, which provides better resistance to chlorides and acidic environments. For chemical processing where aggressive chemicals are used, 316L is recommended. -
Q: Can you customize the slot size to exactly 0.2mm, 0.5mm, etc.?
A: Yes, we can manufacture any slot size between 0.1mm and 5mm in precise increments. Please provide your required micron or millimeter specification. -
Q: How do I clean the Johnson wedge screen?
A: The V-shaped design allows easy backwashing with water or air. For heavy fouling, chemical cleaning or ultrasonic cleaning can be used. Always consult with our technical team for best practices. -
Q: What is the maximum pressure rating of your wedge wire screens?
A: Pressure rating depends on the screen diameter, wire thickness, and support rod spacing. Typically, our screens withstand up to 10 bar (150 psi) for standard configurations. For higher pressures, we can reinforce the structure. -
Q: Do you offer samples for testing?
A: Yes, we provide free samples of 200mm length for evaluation. You only pay for shipping. Contact our sales team to request a sample with your desired slot size. -
Q: What welding method is used to attach the wedge wire to support rods?
A: We use resistance welding (projection welding) to ensure strong, consistent joints without filler metal, maintaining corrosion resistance. -
Q: Can you supply screens with flanges or threaded ends?
A: Absolutely. We can weld flanges (ANSI, DIN, JIS) or thread ends (NPT, BSP) according to your requirements. -
Q: What is the typical lead time for an order?
A: For standard specifications, lead time is 15-20 working days. For custom dimensions or large quantities, please allow 25-30 days. We will confirm the schedule upon order.
