Pre-Packed screen mainly consists of perforated base pipe, sand control filtration jacket, and stainless steel outer protective shroud.

The base pipe is of API casing or API tubing. The sand control filtration jacket is made of multilayer

stainless steel precise microspore weaves. All parts of Pre-Packed are welded together.

Pre-Packed screen is a new efficient technology of mechanical sand control with excellent performance

in practice by its high permeability, high strength, high deformation adaptive capacity,

high reliability and good anti-corrosion property.

These screens are often the best choice for use in unconsolidated sand and gravel aquifers. They are constructed by winding and attached

with a triangular strand of wire around a set of vertical rods. The triangular design is used with the flat face towards

the aquifer and the triangular face towards the pump. This design allows small particles to pass completely

through the screen without becoming wedged in and clogging the screen.
