20 25 30 Micron Mine Sieve Johnson Tube Corrosion Resistent

20 25 30 Micron Stainless Steel Mine Sieve Johnson Water Filter Cartridge Wedge Screen Tube

Product Description

Johnson tube, also called filter tube, is composed of V-shaped winding wire and support bar, and each intersection is connected by welding, with strong structure and good mechanical properties. The V-shaped profile avoids clogging and at the same time ensures smooth water flow. The continuous gap has a larger water area, and at the same time reduces the penetration rate of groundwater, prevents sand from entering the pipe under a larger water pressure, and has better sand filtering performance. The gap can also be changed according to different geology.

It is stamped by a punch through a die, and the outer protective sleeve can also be spirally welded. The filter tube can be made of stainless steel 304, 316, 316L, and the multi-layer sand control filter sleeve and outer protective sleeve can be made according to the needs of users.

Feature

1. Multi-layer sand control filter sets have high-efficiency sand control performance, which can better block formation sand particles and meet the needs of underground sand control.

2. Uniform filter holes, high permeability and anti-blocking performance.

3. Large filtration area and low flow resistance.

4. The stainless steel material has excellent corrosion resistance, acid, alkali, and salt corrosion, which can meet the special requirements of oil wells, and the gap will not gradually become larger due to corrosion.

5. The multi-layer structure is welded together, which can make the filter hole stable and have a strong anti-deformation ability.
