Spiral Welded Filter Tube

spiral welded filter tube is also called Sand Control Screen.

Product performance and features: 1. Unique design of filter ring2. With side opening exterior protection cover(optional)3. Center tube hai unique spiral pattern4. Excellent corrosion-resisting5. Easy for installation, less work time

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 propertiesCenter 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.

Application Scope of The Products: 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.
