Features of Sand Control Screen
1.Stainless steel filter media has been adopted, with high reliability and collapse resistance in sand control;
2.High permeability, large area flow and production rate is high;
3.Small outer diameter, light weight, easy to push along the long horizontal section;
4.Anti-acid and alkaline, anti-high temperature, longer service life;
5.Sand Control Screen samples deformed to75% and 40% of original diameter with virtually no increase in sand production;
6.Simple construction, easy for operation.
