Johnson Screen Pipe also be named Wedge wire screen mesh, Wedge Wire Screen For Pulp Filter, Johnson screen, include the wire Screen tube, wedge wire screen cylinder, wedge wire screen tube, Filter Candle, Drum screen, profile wire screen cylinder and so on.
Johnson Screen Pipe For Filteration is made by winding cold-rolled wire, approximately triangular in cross section, around a circular array of the longitudinal rods. The wire is attached to the rods by welding, producing rigid one-piece units having high strength characteristics at minimum weights.The wire is attached to the rods by welding, producing rigid one-piece units having high strength characteristics at minimum weights.There is a fixed value slot between each v wire, and the continuous slot, designed to provide maximum open are to reduce entrance velocity, increase hydraulic efficiency and promote more effective development.

Detailed Photos
- Before the products are shipped, we will strictly measure the products according to the testing procedures to ensure that the exported products meet the customized needs of customers.
- Not easy to jam
the special V shaped wire, make the hole of screen outside face is smaller than inside, so the hole is not easy to jam.
- Uniform slot
The CNC machine tools strictly control the gap between the wire, so that the gap is even.
- Strong corrosion resistance
Stainless steel 304 have the high corrosion resistance
- Large flow rate: this kind of screen pipe has a relatively small resistance. Compared with the plastic filter element with similar overall size, it greatly increases its flow area, so under the same resistance, the flow rate increases. In other words, in the case of the same output, the number of filter elements can be reduced accordingly.
- Adjustable gap: different users, using different filter equipment and filter media, have different requirements for the gap of the internal wire wound screen. Because the screen pipe is continuously welded on the equipment, the gap between stainless steel trapezoidal wires can be adjusted.
The following is the machining welding process
Our rigorous quality control process ensures you receive a reliable product that meets the highest standards.
