Customized Sand Mill Filter Water Well Filter Mesh Screen Pipe Welded Slotted Johnson Screen Tube
Johnson Screen Tube/pipe is a specialized type of well screen used in water wells, oil wells, and environmental monitoring applications. It is designed to allow the flow of fluids (water, oil) into the well while preventing the entry of sediment, sand, and other debris. This ensures efficient and sustainable extraction of resources while maintaining the integrity of the well.
Slot Design:
Johnson screens feature continuous, narrow slots that are precisely cut into the screen material. These slots are designed to match the grain size of the surrounding aquifer or formation, allowing water or hydrocarbons to flow in while blocking unwanted particles
Material:
Typically made from durable materials such as stainless steel, carbon steel, or other corrosion-resistant alloys. This ensures longevity and resistance to harsh environmental conditions.
V-Shaped Wire Wrapping:
The screens are constructed using V-shaped wires wrapped around a support structure (such as a perforated base pipe). The V-shape helps prevent clogging and allows for self-cleaning as fluid flows through the screen.
Strength and Durability:
Johnson screens are known for their high strength and resistance to collapse, making them suitable for deep wells and high-pressure environments.
