一、Specification:

Slotted wedge wire screen filter cylinder are welded by profile V-wire and support wires,it is also called Johnson screen. It has large  filter area because of big opening,vee 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.

Metal wedge wire filter cartridge is formed by welding wire(cross section is wedge)through a special welding technology welded on the support wire, use Special equipment for resistance welding, high welding strength, uniform gap, strong corrosion resistance, effective filter area, high penetration efficiency, simple structure, minimum aperture 25μm, arbitrarily chosen by the customer.

     The product is especially suitable for fluids containing wax, asphalt and high viscosity.Widely used in coarse and fine filtration of water treatment of power oil wells, gas wells, wells, chemical, mining, paper making, environmental protection, metallurgy, food, sand, Decoration and other industries

三、Features:

     High mechanical strength, can withstand greater pressure Uniform aperture, form uniform filter cake, beneficial backwash regeneration Wedge-shaped filter gap, improve backwash regeneration capacity. High pressure, high temperature, anti-aging, corrosion resistant, available for many types liquid.Almost two-dimensional filter, without particle accumulation, can gather energy when backwash, good backwash effect
