Johnson screen (also known as wedge wire screen,or water well
screen, or wire wrapped screen) are manufactured by a v or wedge
shaped wire around an internal array of longitudinal support rods.
The world advanced all-weld technology is used with each
intersecting point of these wire fusion welded,which creates the
robust construction and excellent mechanical performance.
The v or wedge shaped profile wire wraps around the support rods
over the full length of the screen creating a continuous slot
opening,hence the screen allows water (oil) to enter your well
freely in ample quantities,while at the same time keeps the
majority of sand and gravel out of the well.

The strainer is a kind of filtered water tubing with the
perforation. It can use with the deep well pump, dive the water
pump, also may use in the water-treating equipment, the
environmental protection, the sea water transforms into the
industrial water and life use water desalination treatment, running
water treatment, water softening treatment, the petroleum industry:
The petroleum product terminal filters and the chemical acid, the
alkali liquid filters, the ethyl alcohol and so on the organic
solution recycling filters.
Johnson Screen consists of V-wire and the longitudinal support
rods. Each intersecting point of these wires is fusion welded, so
it has sturdy construction and good mechanical property.
The V-shape section plane can avoid blockage, and make sure of the
unimpeded water. 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 water well screen
can filter sand better.
