Stainless steel johnson wedge wire screen filter tube/ deep well filter screen pipe

Stainless steel johnson wedge wire screen filter tube/ deep well filter screen pipe

Stainless steel johnson wedge wire screen filter tube/ deep well filter screen pipe is made of wedge wire . Iis a welded steel structure, mainly used for filtration, separation and retention media.It consists of surface profiles, usually V-shaped, that are resistance welded onto support profiles.The support profiles are rods in the axial direction of the tube. The surface profiles are spirally wound around the support profiles,The distance between the surface profiles is controlled very accurately, as it forms the slot through which the filtrate flows.

Specification of Stainless steel johnson wedge wire screen filter tube/ deep well filter screen pipe

Stainless steel johnson wedge wire screen filter tube/ deep well filter screen pipe has the following advantage:

1.Non-clogging: the continuous slot formed by the V-shaped surface wires ensures a two-point contact between the particles and the slot, which minimizes clogging.

2.High-precision slot sizes: precise slot sizes are available to meet customers requirements.

3.Surface filtration: the V-shaped surface wires allow easy cleaning by mechanical scraping or back flushing.

4.Low pressure-drop

5.Strong construction: for most applications, the wedge wire screen is self-supporting, because of the welding at each intersection.

Principle of Stainless steel johnson wedge wire screen filter tube/ deep well filter screen pipe

1.During the filter cycle, the solid are deposited on the smooth surface, This 'cake' atcs as an extre filter for finer parcticles, The fines that slip through do not get stuck in the conical slots.

2.By reversing the flow, the cake and dirt are removed from the filter surface.
