Johnson - Screen Pipe for Filteration

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.

• 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.

• Heavy oil, sand oil, light oil, SAGD, CBM, bitumen, thermal
• Water injection, bi-modal sand, carbonates, thin pay
• Horizontal, vertical , deviated oil and gas and water wells
