Johnson tube

      The Johnson tube, also known as the filter tube, is composed of a V-shaped wire and a support strip. Each intersection is welded by a welded joint, and the structure is firm and the mechanical properties are good. The V-shaped profile avoids blockages while ensuring unimpeded water flow. The continuous gap has a larger water passing area, and at the same time, the groundwater permeation speed is reduced, and the sand is prevented from entering the tube under a large water pressure, and the sand filtering property is better, and the gap can also be changed according to different geology.

  Material: 304, 304L, 316L, etc.

  Performance characteristics:

  1. With high-efficiency sand control performance, it can better block the formation sand and meet the needs of underground sand control.

  2. The filter holes are uniform, and the permeability and anti-blocking performance are high.

  3. The filtering area is large and the flow resistance is small.

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

  5. The multi-layer structure is welded integrally, which makes the filter hole stable and has strong anti-deformation ability.
