Structural principle of wire wrapped screen

Wire wrapped screen is actually using a standard oil casing, on the body in accordance with the design requirements for laser drilling after slotting, then dense winding special stainless steel wire welded together. Continuous wire around like a complete whole, uniform and compact size of the gap, with the maximum amount withstand high pressure performance. It is widely used in oil, gas, wells sand process.
Steel wire around the trapezoidal screen use, so that the gap formed between the Vee-shaped sieve openings to ensure the smoothness of water filtration. Wire ladder sustained wound on the circumference to form a continuous string of high-density uniform gap, to ensure that the screen opening area and a non-blocking, high density and avoids the accumulation of sediment, the relative increase productivity, extending the oil well pump inspection cycle.
