As a leading manufacturer established in 1998, Anping County Boli Hardware Wiremesh Products Factory brings over two decades of expertise to the production of high-performance Johnson Filter for Oil & Gas Industry, 316 Stainless Steel, 0.3mm Slot, 2" Flange. Our factory specializes in precision-engineered wire mesh solutions, and this filter is designed to meet the demanding requirements of oil and gas separation, filtration, and well completion. With an annual export value of US$5–10 million and shipments to global markets including North America, South America, Europe, and the Middle East, we ensure every product delivers reliable performance under extreme conditions.
The Johnson filter, also known as a wedge wire screen or profile wire screen, is constructed from premium 316 stainless steel to withstand corrosive environments and high pressures. The 0.3mm slot width offers precise filtration of fine particles while maintaining high flow rates, making it ideal for sand control, gravel packing, and liquid-solid separation in oil and gas applications. The 2-inch flange connection allows for easy installation and secure sealing within existing piping systems.
Key Features & Specifications
- Superior Corrosion Resistance: 316 stainless steel provides excellent resistance to chlorides, acids, and other harsh chemicals commonly found in oil and gas environments.
- Precision Slot Width: 0.3mm (±0.02mm tolerance) ensures accurate particle retention and consistent filtration efficiency.
- High Open Area: Wedge wire design maximizes open area (up to 60%) for low pressure drop and high flow capacity.
- Robust Construction: Continuous V-shaped profile wire wound on support rods creates a strong, self-cleaning structure that resists clogging.
- Easy Installation: 2" flange connection conforms to standard ANSI/ASME B16.5 specifications for quick and leak-proof assembly.
- Customizable Options: Available in various lengths, slot sizes (0.1mm to 5mm), flange sizes, and end connections (threaded, welded, etc.).
- Long Service Life: Designed for harsh downhole and surface conditions, withstanding temperatures up to 400°C and high differential pressures.

Frequently Asked Questions
-
What is the difference between a Johnson filter and a standard wire mesh screen?
Johnson filters use a continuous V-shaped wedge wire wound on support rods, creating a slot with a smooth inner surface. This design offers higher strength, self-cleaning capability, and more precise slot control compared to woven mesh, making it ideal for demanding oil and gas filtration. -
Can the 0.3mm slot filter handle fine sand and silt?
Yes, the 0.3mm slot is designed to retain particles larger than 0.3mm, effectively filtering sand, silt, and other solids commonly found in oil and gas production. For finer requirements, we offer slot sizes down to 0.1mm. -
What flange standards are available?
Our standard 2" flange is ANSI 150#, but we can supply ANSI 300#, 600#, DIN PN16/PN40, JIS 10K/20K, and other custom sizes upon request. -
How do I clean the filter if it becomes clogged?
The wedge wire design is self-cleaning to some extent due to its V-shape, but if needed, the filter can be backwashed, chemically cleaned, or mechanically brushed. Stainless steel construction allows repeated cleaning without degradation. -
What is the maximum pressure rating?
Pressure rating depends on the filter dimensions, wall thickness, and flange class. For a standard 2" flange ANSI 150#, the maximum allowable working pressure is approximately 285 psi at 100°F. Higher pressure ratings are available with heavier wire and flanges—please contact us for your specific parameters. -
Can you provide material certifications?
Yes, we can provide mill test reports (MTR) for the 316 stainless steel material, as well as dimensional inspection reports upon request. -
What is the typical lead time for custom orders?
Standard sizes with 2" flange and 0.3mm slot are typically shipped within 15–20 working days. Custom orders may require 25–35 working days depending on complexity and quantity. -
Do you offer samples for testing?
Yes, we can provide small samples (e.g., 6-inch length) for performance evaluation. Please contact us with your requirements and we will arrange a sample with a nominal fee.
