304 316 316L Stainless Steel Johnson Well Screen Screen Pipe Johnson Tube Wedge Wire Screen Filter
The Johnson Screen Tube, also referred to as the wedge wire screen tube or wrapped wire tubes, represents the pinnacle of precision engineering. Constructed by wrapping a V-shaped wire meticulously around an internal array of longitudinal support rods, each intersecting point of these wires is expertly fusion welded. This results in a robust structure with exceptional mechanical properties. The innovative wedge-shaped section plane is designed to resist blockage, ensuring a seamless flow of water.
Slot tubes are available with custom-designed endpieces, offering the perfect solution for any attachment or reinforcement requirements.
We offer a diverse range of wedge wire slot tubes, tailored to meet various specifications. Custom-made end fittings are available to perfectly match your specific application needs, ensuring maximum efficiency and performance.
