Composed of a base pipe, stainless steel flush filter sleeve, and support ring. The base pipe is made of casing or oil pipe drilling that meets API standards, and the punching filter sleeve is made of high-quality stainless steel material, which is formed into high-density spatial stripes through CNC precision punching technology. The punching filter sleeve is welded to the base pipe through a support ring. According to actual needs, an outer protective cover can be added outside the filter sleeve to enhance its protection.

Product Features
1. Precise and controllable gaps
The width of the flushing seam can be precisely controlled within the range of 0.15~1.0mm, with a seam width accuracy of ± 0.03mm, which can better match the formation sand with different particle sizes and meet the needs of underground sand control.
2. Excellent corrosion resistance performance
The stainless steel flushing filter sleeve is resistant to acid, alkali, and salt corrosion, and is suitable for the special requirements of wells containing H2S, CO2, and high Cl -. Its gaps will not gradually widen due to corrosion after long-term use.
3. Excellent overall strength and deformation resistance
The internal of the flushing filter sleeve is supported by a base pipe, and an external protective sleeve can be added as needed to enhance protection. The overall strength of the drilling base pipe is only 2-3% lower than that of standard casing/tubing, and it has sufficient overall strength to resist the compression deformation of the formation. Even when there is local deformation, the gap in the compressed area does not increase, and the reliability of sand control is high.
4. High density gaps, low flow resistance
The gap density is 3-5 times that of ordinary slotted screen pipes, with low flow resistance, which is beneficial for increasing oil and gas production.
5. Good processability has achieved high efficiency, low cost, and large-scale production.
6. With a 90 ° open cross-section, it has higher self-cleaning ability and ensures long-term stable production.
Widely used in industries such as petroleum, natural gas, and water well sand control, mainly for carbonate and volcanic reservoirs, as well as sandstone reservoirs with medium coarse sand grain size,
