304, 316, 316L Stainless Steel Screen for Johnson Wells Screen Pipe Johnson Tube Wedge Wire Screen Filter
The Johnson Screen Tube, also known as the wedge wire screen tube, wrapped wire tubes, or wire wrapped screen pipe, is an engineering marvel. Meticulously crafted by wrapping a V or wedge-shaped wire around an array of internal longitudinal support rods, each intersection is fusion welded for unparalleled sturdiness and mechanical integrity. Its innovative wedge-shaped section design effectively prevents blockages, ensuring seamless water flow with unyielding reliability.
Our slot tubes come equipped with essential endpieces, perfectly designed for easy attachments and reinforced strength, tailored to your specific needs.
