This type of paper mill pressure screens made up of rods and warp, the rod can be round wire,triangular wire and trapezoid wire.The wire is welded to the rods and produces a rigid unit that has high strength and minimum weight. The warp is triangular wire(v-shape wire).The water well screens have a structure and high open area;as well as accurate slot dimension. well screen cylinder have heat -resistant,anti-corrosive,good machine capability,last long ,safety and reliability and so on.

Paper Mill Pressure Screens are welded by profile V-wire and support wires,it is also called Wedge Wire Screen. It has large filter area because of big opening,Wedge Wire structure are easy for automatic back washing and avoid pipe blocking.The pressure will be reduced when water flows in for greater filter area,avoid the grains of sand flow in the wedge wire tube in the high pressure conditions,so extend the pipe”s life . Between the same length,diameter and slot size,wedge wire pipe is thrice than bridge filter pipes. Moreover, we have inside perforated metal and wedge wire tube outside filter.
