Description
1. Product Overview
The Stainless Steel Screen Pipe (also known as Johnson screen) is manufactured with V-shaped profile wire which is spirally wound around a cage of longitudinal support rods. Each intersecting point of these wires is fusion welded to ensure robust structural integrity.
The pitch of winding gives different spacing between two adjacent turns of wire. This highly precise spacing provides the necessary passage for water, oil, or gas to enter while effectively filtering out sand and particulates.
2. Features & Advantages
- A continuous slot opening which significantly increases the available open area (up to 60%), thus providing greater access to the water or oil-bearing zone.
- A “V” shaped profile wire which fundamentally avoids clogging and ensures an uninterrupted, smooth flow.
- A uniform and efficient well development due to the continuous slot opening design.
- Ladder-like wire welded screens have a highly strong structure and high open area, as well as accurate slot dimensions.
- These welded screens feature easy backwashing, long-lasting durability, supreme safety and reliability, as well as a comprehensively low overall cost.

4. Wide Applications
Due to its outstanding anti-clogging properties and high structural strength, the stainless steel screen pipe is heavily relied upon in a variety of sectors:
- Water wells, Oil wells, and Gas wells (Sand control screens).
- Water treatment equipment and Environmental protection facilities.
- Seawater desalination plants.
- Chemical industry and Architectural applications.
5. Manufacturing Process
The core manufacturing process involves high-precision CNC equipment that spirally winds the V-shaped profile wire around the support rods. Each intersection is electrically resistance-welded to create a single, continuous, extremely robust cylinder with perfectly calibrated slot dimensions.
