Wire strainer wrapped in stainless steel 304 / 304L

Function and Characteristics:

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.
