Construction:Pre-packed screen is comprised of six parts (from outer to inner) - outer screen, outer support rod, pre-packed gravel, inner screen, inner support rods and base pipe. This is a typical model of dual-screen prepack which features double wire wrapped screens. 

The perforated base pipe is covered by inner wire wrapped jacket, whose diameter is smaller than the outer jacket. Between the two layers of jackets, an annular void is packed with silica sand with the appropriate size. The sand is coated by resin or ceramic beads. The gauge of the jacket wire is determined by the packed sand, while the size of the sand is determined by the formulation particle size distribution.

Materials:Pre-packed screens can be fabricated in stainless steel 304, 316L, low carbon steel or other special alloys like Monel 400. Materials are available for specific alloy as required.
