Sand control 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 sand control screen are welded together.
Sand control 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.
Sand control Screen Features Materials and Anticorrosion Ability.
1. For common wells, the base pipe is API casing or tubing (J55, N80, L80,etc.). Sand control filtration jacket and protective shroud are made of high quality stainless steel.
They consist of two screens or multilayer screen.
