304 316 316L Stainless Steel Screen Johnson Well Screen Pipe Johnson Tube Wedge Wire Screen Filter
The Johnson Screen Tube, also renowned as the wedge wire screen tube, is engineered with precision. These wrapped wire tubes, also known as wire wrapped screen pipes, are meticulously crafted by spirally winding a v-shaped or wedge-shaped wire around a robust structure of longitudinal support rods. Each intersecting point of these wires is expertly fusion welded, resulting in an exceptionally sturdy construction with superior mechanical properties. The innovative wedge-shaped section is designed to prevent blockage and ensure an unimpeded flow of water, making it an ideal choice for a variety of applications.
Slot tubes are available with customizable endpieces designed for secure attachments and/or reinforcements, ensuring adaptability to specific application requirements.
We offer a wide range of wedge wire slot tubes tailored to diverse specifications, including bespoke end fittings that perfectly align with your unique application needs.
