Exquisite 304 316 316L Stainless Steel Johnson Well Screens screen Innovative Pipe Johnson Tube Wedge Wire Screen Filter
The Johnson Screen Tube, often referred to as the wedge wire screen tube, wrapped wire tubes, or wire wrapped screen pipe, is meticulously crafted. Constructed by intricately wrapping a v-shaped or wedge-shaped wire around an internal array of longitudinal support rods, every intersecting point of these wires is seamlessly fusion welded. This ensures a robust construction and superior mechanical properties. The wedge-shaped section design brilliantly minimizes the risk of blockage, thereby guaranteeing a continuous and efficient flow of water.
Slot tubes are available with precision-engineered endpieces, tailored for optimal attachments and/or reinforcements.
We proudly offer wedge wire slot tubes in a diverse range of specifications, including custom-crafted end fittings designed to perfectly suit your unique application requirements.
