Sand Control Screens

Our company "HEBEI HENGYING WIRE CLOTH CO., LTD---HENGYING" has developed together with the relevant scientific research organizations series filter products for petroleum chemical filtration:Oil sand control screen (anti-sand filter blocks), spiral welded stainless steel filter tube (spiral welded pipe), straight seam welded stainless

steel filter tubes, well received by the oil field customers.

Product performance and features:

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-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.

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.

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 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.
