Precise Punched Slot Screen--PPS
Introduction
1.Spiral Welded Pipe
Perforated seam is welded in straight line; 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 to 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.
2.Center tube has unique spiral pattern
Center tube has 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.
3.Excellent anti-corrosion properties
Center 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
sandcontrol 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.
Features and Benefits
1The precisely punching technique, machining tolerance under 0.05 mm ,meet the high filter precision
requirement;
2Bridge slots (90 degree inflow surface) are formed to induct flow ,reduce the erosion of the sand and enhance self-cleaning ability;
3Spiral welding forming procedure ensures the rigid filtering shroud;
4API tubing or casing is used as the base pipe, and helically perforated, to give higher base pipe mechanical strength than the slotted screen;
5High quality stainless steel and realizing excellent corrosion resistant ability;
6Screen O.D. is smaller than equivalent coupling, to give out great tripping in performance and reduce the operation time.
Application Scope
Sand screen can be used for vertical wells, the inclined shaft, horizontal wells and various gas, oil and water wells. Can be used individually as sand control tube, also can be used together with filling.
From the inside to the outside, the 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, the new type of sand control screen has excellent performance property. It is the result of a highly effective new technology in mechanical
sand control. This is also our patented product.
