Johnson Screen Pipe For Filteration is made by winding cold-rolled wire, approximately triangular in cross-section, around a circular array of 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 area to reduce entrance velocity, increase hydraulic efficiency and promote more effective development.

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.
The filter rating is 0.05mm-100mm.
Main material is AISI304, AISI316, AISI316L,Hastelloy etc.
Connectors and the ending according to client’s request
We also can produce the specific sizes according to clients’ request, design the screen according the usage.

Johnson Screen Pipe Characteristics:
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.
Slot even
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. In this way, it can meet the needs of different users without increasing the cost, and the plastic filter element needs to adjust the gap to make the mold again, so it is not easy to meet the needs of users. The small gap can reach 20 microns.
