As a leading manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory specializes in producing high-quality Oil and Gas Well Screens made from 304 Stainless Steel with a precise 0.5mm slot for petroleum extraction. Our decades of experience in the wire mesh industry ensure that each screen delivers exceptional filtration efficiency, mechanical strength, and long-term durability. Designed for the most demanding downhole environments, our well screens effectively control sand production while maximizing fluid flow, directly contributing to improved well productivity and reduced maintenance costs.
Our well screens are manufactured using advanced wire wrapping technology, ensuring uniform slot openings and consistent performance. The 304 stainless steel material provides excellent corrosion resistance against hydrogen sulfide, carbon dioxide, and other corrosive elements commonly found in oil and gas reservoirs. With an annual export value of US$5-10 million, we serve clients across North America, South America, Europe, Africa, Oceania, and the Middle East, delivering products that meet rigorous international standards.
Key Features & Benefits
- Precision 0.5mm Slot Opening: Effectively filters formation sand while allowing high flow rates, reducing pressure drop and enhancing production efficiency.
- 304 Stainless Steel Construction: Superior resistance to corrosion, erosion, and high-temperature environments, ensuring long service life even in harsh downhole conditions.
- High Structural Integrity: Wrapped wire design with strong support rods provides excellent collapse resistance and tensile strength (≥520 MPa), suitable for deep wells.
- Customizable Dimensions: Available in various diameters (2-12 inches), lengths (1-6 meters), and connection types (threaded, flanged, or welded) to fit specific well configurations.
- Uniform Slot Distribution: Computer-controlled winding ensures consistent spacing across the entire screen, preventing localized clogging and maintaining stable filtration performance.
- Easy Installation & Maintenance: Lightweight yet robust design simplifies handling and reduces rig time. The smooth surface minimizes scale buildup and facilitates cleaning.

Frequently Asked Questions
Q1: What is the difference between 304 and 316 stainless steel for well screens?
A: 304 stainless steel offers excellent corrosion resistance for most oil and gas applications. 316 stainless steel provides higher resistance to chlorides and acidic environments. For standard petroleum extraction, 304 is often sufficient. We can also supply 316 or 316L upon request.
Q2: Can the 0.5mm slot width be customized to other sizes?
A: Yes, slot widths from 0.1mm to 3mm are available. Contact our sales team with your specific formation sand analysis to recommend the optimal slot size.
Q3: What is the maximum length of a single screen section?
A: Typically up to 6 meters per section. Longer sections can be connected via couplings or welded joints. Custom lengths are available upon request.
Q4: How do you ensure the slot uniformity?
A: Our machines are CNC-controlled with continuous tension monitoring. Each screen is inspected with feeler gauges and automated optical systems to guarantee slot tolerance within ±0.02mm.
Q5: What connections do you offer?
A: We provide threaded connections (API standard), flanged, or plain ends for welding. Special couplings can be manufactured per your specification.
Q6: How long is the delivery time for a typical order?
A: For standard sizes, delivery is 15-25 working days after order confirmation. Custom orders may require 30-40 working days. We keep a stock of common diameters for quick shipment.
Q7: Can you provide samples for testing?
A: Yes, sample sections (e.g., 300mm length) are available. Please contact us to discuss sample cost and shipping.
Q8: What is the recommended maintenance for well screens?
A: Regular monitoring of production rates and pressure drop is advised. If clogging occurs, chemical cleaning or backwashing can be performed. Our screens are designed to withstand multiple cleaning cycles.
