Welcome to Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer since 1998 with an annual export value of US$5-10 million, serving markets across North America, South America, Europe, Southeast Asia, Africa, and more. Our Continuous Slot Wedge Wire Well Screen in 316L stainless steel, 6-inch diameter, 2m length, and 0.3mm opening, is engineered for maximum efficiency and durability in demanding well filtration applications. This screen combines precision slot geometry with robust construction to deliver superior sand control, high flow rates, and long service life, making it an ideal choice for water wells, oil & gas wells, and geothermal projects.
Key Features & Technical Specifications
- Material: Premium 316L stainless steel – excellent corrosion resistance in harsh environments, including saline, acidic, and high-temperature conditions.
- Slot Design: Continuous V-shaped wedge wire profile prevents clogging, allows self-cleaning, and ensures consistent slot opening of 0.3mm ± 0.02mm.
- Structural Strength: Heavy-duty support rods and welded joints provide high collapse resistance, suitable for deep wells (up to 500m+ depth).
- Flow Efficiency: Open area up to 60% due to wedge wire structure, minimizing pressure drop and maximizing production rate.
- Standard Dimensions: 6-inch (152.4mm) outer diameter, 2-meter length per section (custom lengths available upon request).
- End Connections: Plain ends standard; threaded or flanged options available for easy installation.

Product Advantages & Benefits for Customers
- Reliable Sand Control: 0.3mm precision slots effectively retain fine sand particles while allowing water/oil to pass freely, reducing pump wear and downtime.
- Long Service Life: 316L material resists rust, pitting, and crevice corrosion even in aggressive groundwater or brine – typical lifespan 5–10 years in normal conditions.
- High Flow Capacity: The wedge wire design provides up to 60% open area, delivering higher flow rates compared to perforated pipe or mesh screens of equal diameter.
- Self-Cleaning Action: V-shaped slots prevent particle bridging and allow easy backwashing, reducing maintenance frequency.
- Customizable Dimensions: Diameter from 2″ to 12″, length up to 6m per section, and slot opening from 0.1mm to 6mm to match your well specifications.
- Easy Installation: Lightweight yet strong, can be coupled with standard adapters; plain end suitable for welding or clamping.

Frequently Asked Questions (FAQ)
Q1: What is the difference between continuous slot and wire-wrapped screen?
A: Continuous slot screen uses a single continuous wire wrapped around support rods, creating a smooth slot with no interruptions. This design minimizes plugging and provides better flow distribution compared to traditional wire-wrapped screens with cross-welded joints.
Q2: Can this screen be used for water wells with high sand content?
A: Yes. The 0.3mm opening is suitable for fine to medium sand formations. For higher sand content, we can supply screens with smaller openings (down to 0.1mm) or larger slot sizes after analyzing your sieve analysis report.
Q3: Is the screen available in different lengths or diameters?
A: Absolutely. We offer custom lengths from 1m to 6m per section, and diameters from 2 inches to 12 inches (or metric sizes). Please contact us with your specific requirements.
Q4: What is the collapse pressure rating of this screen?
A: The 6-inch 316L screen with 0.3mm slot typically has a collapse strength of ≥20 MPa, which is sufficient for most deep well applications (up to 2000m). For higher pressures, we can reinforce the support rod design.
Q5: Do you provide end connections like threads or flanges?
A: Yes. Plain ends are standard, but we can weld male/female threads, grooved ends, or flanges per your drawing. Lead time may vary.
Q6: How long is the delivery time?
A: For standard sizes (6″ x 2m, 0.3mm), we usually ship within 15-20 working days after order confirmation. Custom orders take 25-35 days depending on complexity.
Q7: What is the minimum order quantity?
A: Our MOQ is 10 pieces for standard screens. For custom specifications, MOQ may be higher. We welcome small trial orders for first-time cooperation.
Q8: Can you provide samples for testing?
A: Yes, we can provide a 30cm sample piece for a nominal fee, which will be deducted from your first order. Contact our sales team for details.
