The PMC screen consists of the parent tube, composite sand control filter mantle, stainless steel exterior protective sleeve, etc. from inside to outside. The parent tube adopts the API standard casing or tubing and the sand control filter mantle is made of stainless steel fine microporous composite filter material adopting a fully welded configuration. Featuring on high permeability, high strength, high anti-deformability, high reliability and high resistance to corrosion, the composite sand control filter mantle is a new efficient technical product of mechanical sand control
Product Characteristics
    Double precision design of sand control mantle: the external protective sleeve adopts punched mantle to filtrate large sand particles with the internal sleeve being a multilayer composite sand control filtering layer. The filtering precision is optimally designed according to the stratum sand size distribution. The structure not only ensures sand control reliability, it also improves the anti-clogging ability of the liner;
   External protective sleeve with bridge-type lateral flow hole: during the running in and operation process, it can well protect the filtering layer and effectively avoid direct erosion and damage caused by the fluid to the filtering layer so as to prolong the service life;
    Multilayer composite sand control filtering layer;
    Changeable filtering structure design of liner: according to the actual condition of stratum, a combination application of various filter materials can be realized to meet the field usage requirement to the greatest extent;
