Structure principle of wire - wound screen

Wire around the screen is in fact a certain specification of oil, casing, in accordance with the design requirements in the body with the laser cutting perforation, and then tight winding special stainless steel wire for welding. Winding like a continuous whole, the gap size uniform and compact, with the greatest amount of high-pressure performance. Is widely used in oil, gas, wells sand control process.   Wire around the screen using trapezoidal wire, so that the gap between the screen to form Vee-shaped openings, to ensure the smoothness of oil and water filtration. Continuous trapezoidal wire wound on the circumference of the column to form a continuous high-density uniform gap to ensure the opening area of the screen and non-blocking, and avoid the accumulation of high-density sediment, cycle.
