Types of wedge wire screen pipe

Wedge wire screen tube has various different types, according to the different standard, here are the detailed introduction of the wedge wire screen tube, just refer to them and know more about the round slot tube and get a reference for choice.

According to the position and direction of surface profiles and support profiles, the wedge wire screen tube can be divided into four types.

  • Radial internal type. The filtering principle is flowing in to out. And the support profile is radial.
  • Radial external type. The filtering principle is flowing out to in. It is the standard type. The support profile is also radial.
  • Axial internal type. The filtering principle is flowing in to out. And the support profile is axial.
  • Axial internal type. The filtering principle is flowing out to in. And the support profile is axial.

According to the surface of wedge wire screen tube
There are two types of wedge wire screen tube seen from the surface. One is the normal types, which has continuous and regular angles on the edge. It is economical, which is suitable for the applications where the accuracy is not very strict. The other type is perfect round type. It is produced by the strict standard, which has better filtering accuracy than the common type. Additional, the perfect round type can be used in the most precise machines and complete the arduous filtering task.

Wire types of wedge wire screen tube
As we all know, the wedge wire screen tube is composed of surface profiles and support profiles. The wire type of surface profile is commonly triangular wire, which is also called V-shaped wire.
The support wire can be triangular wire, round wire and trapezoid wire.
