Oil filter tube

Oil filter tube
Material: carbon steel, stainless steel punching net
Specifications: Can be customized according to customer needs a variety of sizes of oil filter tube. Welcome to make drawings or specific specifications to build.
Features: The use of precision punching technology, stainless steel punching filter flushing opening in the side, to reduce the sand layer of the direct erosion of the punched seam. Blank gap processing range between 20mm and 0.7mm. Blank gap uniformity can ensure that the processing error within the range of 0.015mm to ensure the accuracy of its filtration requirements. Welding seam using straight seam welding; or the use of spiral welding formation, significantly improved the filter sleeve strength. In the local external squeeze, the pressure in the external force, the gap is reduced or closed to ensure the reliability of sand control.
Principle of action: formation sand is blocked in the filter tube, the formation of oil, gas or water through the gap gap, and then through the drilling hole into the screen tube. To achieve sand control approach.
