Product Details

High Opening Area Water Well Screens

Water Well Screens are designed for construction of well depths of 100 m, 200 m, 350 m & 600 m. Custom deep wells available upon request. It is manufactured using our unique digital controlled machinery in which a continuous length of profile wire of a triangular section is fusion welded onto support rods to form a pipe screen.

This 'V' shaped profile wire is wound around the support rods over the full length of the screen thus creating a continuous slot opening.

Well screens have high opening area, as well as accurate slot dimension.

When compared to conventional perforated liners, OASIS Water Well Screens have superior open area due to their continuous slot openings.

The Benefits of using profile wire well screens rather than perforated screen:

Reduced energy consumption and increased water flow.

Reduced erosion of entry surfaces and increased well life.

Allowing a uniform and efficient well development.

Reduced significantly potential pump damage and subsequent maintenance costs.

Compared with carbon or galvanized steel, Stainless Steel Well Screens have many advantages:

1. Continuous opening has greatly increased the water flow area, so offers a better contact with the aquifer.

2. V-type profile of the structure to avoid clogging and ensure smooth flow.

3. Continuous long-term effective use of the pore.

4. Trapezoidal shape filter screen offers a solid structure, high porosity, and accurate poring.

5. Trapezoidal wire stainless steel filter screen is easy for washing, long service life, safe, reliable, comprehensive and low cost.

6. Heat-resisting, anti-corrosive, good machine capability

7. Long life span, safety and reliability

Use:

Stainless steel water well screen can use with the deep well pump, water diving pump, also may use in the water-treating equipment, the environmental protection, the sea water transforms into the industrial water and life use water desalination treatment, running water treatment, water softening treatment, the petroleum industry as the petroleum product terminal filters and the chemical acid, the alkali liquid filters, the ethyl alcohol and the organic solution recycling filters and so on.
