As a leading manufacturer with over 25 years of industry experience, Anping County Boli Hardware Wiremesh Products Factory is proud to present our premium Stainless Steel Well Screen with 0.020 inch Slot, 4-inch OD. This well screen is crafted from high-grade stainless steel (304 or 316L) to deliver exceptional corrosion resistance and long service life in demanding groundwater and environmental applications. Our factory, established in 1998 and exporting over US$5 million annually, ensures every product meets rigorous quality standards. The 0.020-inch (0.5 mm) slot opening is precisely machined to provide optimal filtration while minimizing clogging, making it ideal for fine sand formations and high-efficiency water wells.
Available in 1m, 2.5m lengths and a 10-inch (254 mm) option, this well screen offers flexibility for various well depths and project requirements. The 4-inch outer diameter ensures compatibility with standard well casings. Each screen is manufactured using advanced continuous slot winding technology, resulting in a V-shaped wire profile that allows maximum open area and consistent slot width. The V-shaped wire profile prevents sand locking and enables easy cleaning, reducing maintenance costs over the system's lifetime.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between 304 and 316L stainless steel for well screens?
A: 304 is suitable for most freshwater applications with moderate corrosion risk. 316L offers superior resistance to chlorides and acidic environments, making it ideal for saltwater, brackish water, or chemical-laden groundwater. Both are available upon request. -
Q: Can I get a slot size other than 0.020 inch?
A: Yes, we offer customizable slot sizes from 0.006 inch to 0.060 inch (0.15 mm to 1.5 mm). Please specify your required slot opening when ordering. -
Q: How do I connect multiple well screen sections?
A: Standard threaded ends (male/female) allow easy coupling. For longer runs, you can use a coupling sleeve. Welded connections are also available for permanent installations. -
Q: What is the maximum well depth for this screen?
A: The screen itself can be used at depths up to 300 meters (1000 feet) depending on wall thickness and material. For deep wells, we recommend 316L and thicker wall options. Please consult our engineering team for deep well designs. -
Q: Do you provide samples before bulk order?
A: Yes, we can provide small samples (e.g., 10-inch length) for testing. Please contact us to arrange sample shipment. -
Q: What is the lead time for a standard order?
A: Lead time is typically 15–25 working days depending on quantity and customization. We maintain a stock of common sizes to expedite delivery. -
Q: How do I clean a clogged well screen?
A: The V-shaped wedge wire design prevents sand locking, but if cleaning is needed, use a high-pressure water jet or chemical cleaning agents compatible with stainless steel. Avoid harsh abrasives. -
Q: Can I order a combination of lengths (1m and 2.5m) in one shipment?
A: Absolutely. We can mix different lengths and slot sizes in a single container to meet your project needs. Just provide a detailed packing list.
