continuous slot pre-pack screen

     Wedge wire Wedge Wire Screen pipe is manufactured by a V or wedge shaped wire around an internal array of longitudinal support rods. Each intersection point of this wire is fusion welded. 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.

Application for continuous slot pre-pack screen:

wedge wire screen of a series of screen laterals connected to either a central-header pipe or a hub, they are important components of ion exchange units, media filters, sand filters, carbon strip vessels, carbon towers, clay filters and in many water and waster water treatment applications.

Function and Characteristics for continuous slot pre-pack screen：

1. The sand filter tubes have the efficient sand prevention performance can preferably forbid the formation particle and fulfill the need of sand control.
2. Even filter pores, high permeability and anti-blocking.
3. Large filtering area, small flow resistance and high oil extraction rate
4. Stainless material has the corrosion resistant ability of antacid, alkali and salt, can easily suit the special requirement of the petroleum well. And the slot wont be enlarged because of the corrosion.
5. Multiple structure was welded together with stable filtering pore which made the strong non-deformability.
