304 316 316L Stainless Steel Screen Johnson Well Screen Pipe Johnson Tube Wedge Wire Screen Filter
The Johnson Screen Tube, also known as the wedge wire screen tube, is a marvel of engineering characterized by its wrapped wire design. These tubes are expertly crafted with a V or wedge-shaped wire meticulously wrapped around an internal array of longitudinal support rods. Each intersecting point of these wires is fusion welded, ensuring a robust construction and excellent mechanical properties. The innovative wedge-shaped section plane helps prevent blockage, offering an unobstructed flow of water, ensuring efficient operation and longevity.
Slot tubes can be tailor-made with the essential endpieces, providing reliable attachments and/or reinforcements to perfectly fit your needs.
We offer a broad range of wedge wire slot tubes, including custom-made end fittings tailored to meet the specific demands of your application. Whatever your specifications, we can deliver the perfect solution.
