Our company"HEBEI HENGYING WIRE CLOTHCO., LTD---HENGYING" has developed together with the relevantscientific research organizations series filter products for petroleum chemicalfiltration: Oil sand control screen (anti-sand filter blocks), spiral weldedstainless steel filter tube (spiral welded pipe), straight seam welded stainlesssteel filter tubes, well received by the oil field customers.
Product performance and features:
SpiralWelded Pipe
Perforatedseam is welded in straight line; with unique spiral distribution formed byspiral welding and greater filter strength. When squeezed in some parts fromexternal, under outside pressure, the forced part will have reduced or closedgap and ensures the reliability of sand control. Made with sophisticatedtechnology, stainless steel filter glove has openings in the side with reduceddirect corrosion to the perforated welded sand pipe. Seam gap in the processingranges between 20 mm-0.7mm. The uniform opening ensures the processingdifference is within the error scope allowed - 0.015 mm, also ensures theaccuracy of its filter requirements. Using high precision perforatingtechnology, the effective slotting length is the three to five times of commoncut seam tube and two to three times of common perforated seam tubes.
Centertube has unique spiral pattern
Centertube has high precision perforated tube with standard oil and glove tubes. Thespiral perforating form of the center tube reduces the opening area of the tubecross section and maintains the strength of the center tube to the maximum. Thesand is blocked outside of the perforated screen while the oil, gas or watergoes through the perforated opening then enters into the screen.

Excellent anti-corrosionproperties
Centertube is API standard tube or oil tube and the high precision perforated filterglove is made of 304 stainless steel materials.
For wellscontaining H2S, CO2, high-Cl that has special requirements, the center tube canbe corrosion-resistant casing or tubing. Screen is acid and alkali resistant andsalt corrosion resistant.
CompoundGrading Sand Control Screen has adopted unique grade sand control with thesurface 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, highreliability, good corrosion resistance, this is the most effective sand controlproducts at this time.

Product Property and Characteristics:
Uniquedesign of filter ring
Grade sandcontrol filter and exterior protection cover are welded with the side ring toform a unit. The times of welding between the filter structure and the centertube are reduced to the minimum, hence greatly reduce the effect of the weldingto the sand strength.

With sideopening exterior protection cover (optional)
Duringtransport, the protection cover can protect the grade sand control filter layer,protect the sand control filter layer from punctured or damaged during theprocedure of entering the well.
In theoil and gas wells production, using of it can effectively prevent the directerosion and damage of the fluid to the grade sand control filter layer and itcan extend the service life of Screen.

ApplicationScope of The Products
Sandscreen can be used for vertical wells, the inclined shaft, horizontal wells andvarious gas, oil and water wells. Can be used individually as sand control tube,also can be used together with filling.
From theinside to the outside, the screen is made with the composite sand filtrationkits, stainless steel protection kits and other components. The basic tubeis API casing or tubing, sand control filters are stainlesssteel precision porous filter composite materials, made of the whole weldedstructure. Because of high penetration, high-intensity, high resistance todeformation, high reliability, good corrosion resistance, the new type of sandcontrol screen has excellent performance property. It is the result of a highlyeffective new technology in mechanical sand control. This is also our patentedproduct.
