High Precision Johnson Screen Plate Welding Machine

Wedge wire screen Internal
Wedge wire screen internals such as outlet baskets,support grids,overlay grids,scallops,center pipes and screen baskets are used in the petrochemical industry to retain the catalyst or other media and to collect the process flow.Typical applications include reforming,hydrotreating and hydrocracking.
Slot opening are usually 1/2 of the minimum dimension of the media or inert balls.The size opening retains the catalyst with minimal pressure drop across the screen.The continuous slot openings provide high open area for better flow and allow only two point contact with the media resulting in the screen being resistant to blinding.Wedge wire screen internals can be costumed
Engineered for the application including installation through a man way.
