Sand Control Screen

              Sand Control Screen mainly consists of perforated base pipe, PMC sand control filt-ration jacket, and stainless steel outer protective shroud. The base pipe is of API casing or API tubing. The PMC sand control filtration jacket is ma-de of multilayer stainless steel precise micropore weaves. All parts of PMC screen are welded together.

              PMC screen is a new efficient technology of mechanical sand control wi-th excellent performance in practice by its high permeability, high strength, high deformation adaptive capacity, high reliability and good anti-corrosion property. PMC screen is a patent technology of HNHT.

              Sand Control Screen Features Materials and Anticorrosion Ability.

              1. For common wells, the base pipe is API casing or tubing (J55, N80, etc.). PMC sand control filtration jacket and protective shroud are made of high quality stainless steel.

              2. For special wells in H2S, CO2 or C1 corrosive environment, the base pi-pe is anti-corrosion casing or tubing, even is stainless steel tubing. PMC sa-nd control filtration jacket and protective shroud are made of high quality st-ainless steel.

              3. Have anti-corrosion ability to acid, alkali, or salts

             Perforated Round Hole Stainless Steel Sand Control Screen, Pipe Type

From the inside to the outside, the sand control screen is made with the composite sand filtration kits, stainless steel protection kits and other components. The basic tube is API casing or tubing, sand control filters are stainless steel precision porous filter composite materials, made of the whole welded structure. Because of high penetration, high-intensity, high resistance to deformation, high reliability, good corrosion resistance, this sand control screen has excellent performance property. It is the result of a highly effective new technology in mechanical sand control.

UBO offers perforated filter tubes for oil field: Oil well sand control screen (anti-sand filter blocks), spiral welded stainless steel filter tube (spiral welded pipe), straight seam welded stainless steel filter tubes.

Perforated straight line pipes are welded with unique spiral distribution formed by spiral welding and greater filter strength. When squeezed in some parts from external, under outside pressure, the forced part will have reduced or closed gap and ensures the reliability of sand control. Made with sophisticated technology, stainless steel filter glove has openings in the side with reduced direct corrosion to the perforated welded sand pipe. Seam gap in the processing ranges between 20 mm-0.7mm. The uniform opening ensures the processing difference is within the error scope allowed - 0.015 mm, also ensures the accuracy of its filter requirements. Using high precision perforating technology, the effective slotting length is the three to five times of common cut seam tube and two to three times of common perforated seam tubes.

Filter Center Tube has unique high precision perforated tube with standard oil and glove tubes. The spiral perforating form of the center tube reduces the opening area of the tube cross section and maintains the strength of the center tube to the maximum. The sand is blocked outside of the perforated screen while the oil, gas or water goes through the perforated opening then enters into the screen.

Features:

Center control tube is API standard tube or oil tube and the high precision perforated filter glove is made of 304 stainless steel materials.

For wells containing H2S, CO2, high-Cl that has special requirements, the center tube can be corrosion-resistant casing or tubing. Screen is acid and alkali resistant and salt corrosion resistant.

Compound Grading Sand Control Screen has adopted unique grade sand control with the surface filter and deep filter combined together to form a double precision. This is the new breakthroughs in the field of mechanical sand control designs. Offering high penetration, high Strength, highly resistant to deformation, high reliability, good corrosion resistance, this is the most effective sand control products at this time.
