Stainless steel Johnson Sand Control screen is composed of V-shaped stainless steel wire and stainless steel support bar. The smooth surface of the filter element is a filter surface, and the gap is a strip, which belongs to the form of surface filtration.

As a variety of automatic filters (such as automatic backwashing, scraper self-cleaning, scraper self-cleaning, sucking self-cleaning filter) filter elements are widely used in various industries of fluid filtration and separation.

Johnson Sand Control Screen Features
In the past, the metal screen woven by metal wire was widely used in the industry. Because of the large contact area between solid particles (catalysts, molecular sieves, and various filters) and wire mesh, particles are easily blocked and stuck in square holes of wire mesh, resulting in increased pressure drop, which makes the device unable to operate, maintenance is also more difficult.

The Johnson wire Sand Control screen has only two contact points with solid particles, so it is not easy to block and jam.

Therefore, compared with other types of wire mesh filters, Johnson screen filter has obvious advantages in filtration and separation. It is not easy to plug, easy to clean, low-pressure drop and other characteristics make it more and more popular.

Advantages of Johnson Sand Control Screen

(1) The opening range is large and the opening rate is high.
(2) Each intersection of the johnson vee wire and the support rod is welded, so the accuracy is high and the gap is accurate.
(3) There are only two points of contact between the continuous gap and the solid particles, which is not easy to plug.
(4) The surface is smooth, the catalyst wears less, the particles are not easy to crush, and the surface roughness of the sieve bar can be as low as 6.3 um.
(5) The sieve mesh with Johnson wedge wire screen wire and connecting rod of different gap sizes and specifications has good strength. If the operating conditions are harsh and the load is large, the strengthening material and connecting rod with large cross section can be selected, and the tensile force of each solder joint can reach 2000-3000N.
(6) Long service life, easy installation, lightweight, more economical.
