Johnson water well screen pipe also be named: v wire water well screens, wire wrapped screens pipe, Johnson Screen, welded wedge wire screen, reversed slot screen, continuous slot pre-pack, water filter, screen cylinders, stainless steel slot tube, reverse rolled screen, strainer pipe, continuous slot wire wrap well screens, pipe base well screen, ribbed-type wire wrapped screen, stainless steel or low carbon galvanized or mild steel wire screen, wire wrapped liner, woven wedge wire screen, slot wire screen tube, well screen, strainer screens, well point screens, oil screen tube, etc

Johnson water well screen pipes are made from V shaped profile wire, which is spirally wound around a cage of longitudinal support rods. Each intersecting point of these wires is fusion welded, with an unique welding process. This spacing gives passage for water to enter. The entire process is completed on fully computerizes machines. The pitch of winding gives different spacing between two adjacent turns of wire.

Advantages of Johnson screen water well pipe for oil filtration

-- Tensile, load, collapse strength

-- Rotating ability during installation

-- High corrosion resistance

-- Very accurate slot opening

-- Minimum risk cementing up

-- Uncomplicated installation

-- Slot opening from 50 micron up to 2000 micron

-- All API and ANSI pipe sizes are available

-- Customized construction:

-- Lower V-wires for reduced OD

-- Higher support rods for more standoff

-- Customized material grades 304/316L/904/Duplex/Alloy 825/625/C276 etc.

-- Customized end-fittings and threaded connections

-- Fixation of screen by welding or shrink fitting of end-rings to the base-pipe

Features of Johnson screen water well pipe for oil filtration

1) They consist of V-shape or wedge shape profile wire and the longitudinal support rods.

2) The consecutive slot have more open area, and it can reduce the speed of the water entering to avoid the sand entering the screen under the great pressure, so it can filter sand better.

3) Each intersecting point of these wires is fusion welded, so it has sturdy construction and good mechanical property.
