As a specialized manufacturer from Anping County Boli Hardware Wiremesh Products Factory (established in 1998), we offer high-quality Continuous Slot Well Screens made of grade 304 stainless steel. With a precise 0.3mm slot width and 50mm outer diameter, our well screens are engineered for effective sand control in water wells, oil wells, and geothermal applications. Our factory has exported over US$5 million annually to markets across North America, South America, Europe, Africa, and Asia, ensuring consistent quality and reliable supply.
These continuous slot screens are manufactured using advanced wedge wire wrapping technology, providing a robust filtration surface that minimizes clogging and maximizes flow efficiency. The 304 stainless steel construction offers excellent corrosion resistance in fresh water, brine, and mild chemical environments, ensuring long service life even in challenging downhole conditions.

Frequently Asked Questions
-
Q: What is the difference between continuous slot and wire-wrapped screen?
A: Continuous slot screens have a V-shaped wire continuously wrapped around a support rod, while wire-wrapped screens may have individual wires. Our continuous slot design offers better strength and consistency. -
Q: Can I get a sample before ordering?
A: Yes, we provide samples for evaluation. Please contact our sales team for sample availability and shipping costs. -
Q: What is the maximum length of a single section?
A: Standard lengths are 1m, 2m, and 3m. Longer sections up to 6 meters are possible upon request, depending on transportation constraints. -
Q: Is the screen suitable for high-temperature geothermal wells?
A: 304 stainless steel can withstand temperatures up to 400°C in non-oxidizing conditions. For extreme environments, we recommend 316L or duplex stainless steel – please inquire. -
Q: How do you pack the well screens for export?
A: We use wooden crates or steel frames with protective wrapping to prevent damage during transit. Custom packaging is available upon request. -
Q: Can you provide a certificate of material?
A: Yes, we can issue a mill test certificate for the 304 stainless steel material upon request. -
Q: What is the lead time for a standard order?
