Wedge Wire Screens(Johnson type screens)
Wedge wire screens(Johnson type screens) are manufactured by a v or dge shaped wire around an internal array of longitudinal support rods. The world advanced all-weld technology is used with each intersectiong point of these wire fusion welded, which creats 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 slots can be changed according to different strata.

Advantages of wedge wire screens(Johnson type screens)
Non-clogging construction: the V-shape section plane of wedge wire screens(Johnson type screens)creates the continuous slot, which can avoid blockage and make sure of the unimpeded water.
Large filtering area: the consecutive slot of wedge wire screens(Johnson type screen) has wider open area, and it reduce the speed of the water entering to avoid
Long service life: wire and support rods are all-welded, which makes wedge wire screens(Johnson type screens) more robust and longer life.
Excellent construction strength: the longitudinal support rods and the continuous slot make the wedge wire screens(Johnsoon type screens) have more excellent pressure-resistant performance.
Specifications and the end connections of wedge wire screens(Johnson type screens) can be fabricated according to customers’ requirements.
