Stainless Steel 304 Downhole Slotted Tube For Groundwater 0.25mm Slot Size
Water well screen is a filter that allows water to enter the pipe from several entry points. The filter can be made from a number of materials. The filter needs to have a large surface area through which water can penetrate. It needs to have non-clogging slots to keep water flowing. It must resist corrosion because it will be in contact with water. It needs to have enough strength to keep the surrounding structure intact.
Water well screen designs should incorporate the following features:
1. Minimum entrance velocity.
2. Maximum open area of screen.
3. Correct design of slots to minimize blockages.
4. Slot size should match aquifer or gravel pack medium.
5. Screen material should be corrosion resistant.
6. Screen should allow for periodic maintenance.
