Selecting the appropriate construction and flow direction for a wedge wire screen depends on the specific requirements of your application and the type of filtration or separation you need to achieve. We provide axial slots and radial slots in FOTI and FITO flow direction. Here are introduction and suggestion to help you make the right choices:
Radial external wedge wire tubes are composed of axial support profile rods and radial surface Vee wires, which are wrapped around support wires and attached to each other by resistance welding.
Radial internal wedge wire types are rolled from flat wedge wire screen panels not continuously spirally wrapped around axial support profiles, that means there are many welding joining points and only flow in one direction (FITO), shown as figure 2.
Axial external wedge wire screen tube or cylinder is rolled from flat wedge wire screen panels and is composed of radial support profile wires and axial surface screen profile wires, which are axial outside the support wire. Because of the flat side of surface screen Vee wires on the outside of the screen, the flow direction of this type is commonly from outside to inside (FOTI), shown as figure 3-1. We can produce specially designed wedge wire tubes, which the flow direction is from inside to outside (FITO), shown as figure 3-2..
The axial wedge wire screen tube or cylinder is comprised of surface screen profile wires oriented axially inside of the screen tube and support profiles oriented radially outside of the tube. Because of screen Vee wires on the inside of the screen, the flow direction of this type is commonly from inside to outside (FITO).
There are two types based on the slot and filter size: the first type is rolled from flat wedge wire screen panels, resulting in multiple welding joining points, shown as figure 4-1, while the second type involves the continuous spiral wrapping of support wires around axial surface wedge wires, shown as figure 4-2.
Except of figure out the flow direction, structure of screen surface profile wires and support wires, there are also a few common strengthening forms for the wedge wire screen tubes or cylinders.
