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

Product Property and Characteristics:

Unique design of filter ring
Grade sand control filter and exterior protection cover are welded with the side ring to form a unit. The times of welding between the filter structure and the center tube are reduced to the minimum, hence greatly reduce the effect of the welding to the sand strength.

With side opening exterior protection

cover (optional)
During transport, the protection cover can protect the grade sand control filter layer, protect the sand control filter layer from punctured or damaged during the procedure of entering the well.
In the oil and gas wells production, using of it can effectively prevent the direct erosion and damage of the fluid to the grade sand control filter layer and it can extend the service life of Screen.
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.

Small external diameter, light weight, easy to move in the long-distance horizontal level.
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. It is the result of a highly effective new technology in mechanical sand control. This is also our patented product.
