As a leading manufacturer with over 25 years of experience, Anping County Boli Hardware Wiremesh Products Factory (established in 1998) proudly presents our 304 Stainless Steel Wedge Wire Screen Filter Element, specifically engineered for the demanding oil and gas industry. Our annual export value of US$5-10 million and global reach across North America, South America, Europe, Asia, Africa, and Oceania reflect our commitment to quality and reliability. This filter element combines superior corrosion resistance, high mechanical strength, and precise slot tolerances to deliver exceptional performance in harsh downhole and surface applications.
The wedge wire screen filter element is designed with a unique V-shaped profile wire wound around support rods, creating a continuous slot opening that is self-cleaning and resistant to clogging. Made from high-quality 304 stainless steel, it offers excellent resistance to corrosion from sour gas, brine, and other corrosive fluids commonly encountered in oil and gas wells. The robust construction ensures long service life even under high pressure and temperature conditions.
Key Features and Benefits:
- High Mechanical Strength: The wedge wire design provides exceptional structural integrity, capable of withstanding high differential pressures and mechanical loads without deformation.
- Precise Slot Opening: Laser or CNC-controlled manufacturing ensures uniform slot widths from 0.1mm to 5mm, guaranteeing accurate filtration and consistent performance.
- Self-Cleaning Capability: The V-shaped profile allows particles to be easily released during backwashing, reducing maintenance frequency and operational costs.
- Corrosion Resistance: 304 stainless steel offers excellent resistance to a wide range of chemicals, including H2S, CO2, and chlorides, making it suitable for both sweet and sour service.
- Customizable Dimensions: Available in various diameters (50mm to 500mm), lengths (up to 6000mm), and end connections (threaded, flanged, or plain) to fit your specific equipment and well configuration.
- Versatile Applications: Ideal for sand control, gravel pack screens, water injection filters, production well screens, and separator vessel internals.

Frequently Asked Questions (FAQ)
1. What is the difference between wedge wire screen and wire mesh screen?
Wedge wire screen uses a V-shaped profile wire wound around support rods, creating a continuous slot that is stronger and more resistant to clogging. Wire mesh is woven and can be less durable under high pressure. Wedge wire is preferred for oil and gas sand control due to its self-cleaning nature and higher mechanical strength.
2. Can you customize the slot size and dimensions?
Yes, we offer full customization. Slot sizes can be produced from 0.1mm to 5mm, and dimensions (diameter, length, end connections) can be tailored to your specific requirements. Please provide your drawing or specifications.
3. Is 304 stainless steel suitable for H2S environments?
304 stainless steel offers good resistance to mild sour service. For severe H2S environments, we recommend our 316L or duplex stainless steel options. Please consult with our technical team for application-specific advice.
4. How do you ensure the slot width accuracy?
We use CNC-controlled winding machines and conduct 100% inspection with precision gauges. Our typical tolerance is ±0.02mm, ensuring consistent filtration performance.
5. What is the typical lead time?
For standard sizes, lead time is 15-20 days. Custom orders typically require 25-30 days, depending on complexity and quantity. We can expedite urgent orders upon request.
6. Do you offer pressure testing certificates?
Yes, we can provide pressure test reports, material certificates (mill test certificates), and dimensional inspection reports upon request. Third-party inspection is also acceptable.
7. Can this product be used for water injection wells?
Absolutely. Our wedge wire screens are widely used in water injection wells for filtration and sand control. The 304 stainless steel material is resistant to corrosion from injection water, and the self-cleaning design helps maintain flow rates.
8. What packaging do you use for export?
We use wooden crates or steel-reinforced boxes to protect the filter elements during shipment. Each unit is individually wrapped with anti-corrosion paper and foam padding. Ports of shipment include Tianjin, Qingdao, Shanghai, and Foshan.
