It is manufactured by a v or wedge shaped wire around an internal array of longitudinal supportrods. Each intersecting point of these wire is fusion welded.
Wedge wire screen is widely used in mining, coal, petroleum, fertilizer, grain, salt industry, environment protection, etc. Sieving liquid, powder and other materials. Petroleum, chemical industry, metallurgy, mining, pharmaceutical purification, drilling liquid purification and other industries use.
Johnson screen have the features of great strength , precision , long service life and a wide range of applications in the field of process and engineering such as waste water treatment , sugar juice filtration , crude oil and natural gas production and vessel internals solving problems of solid / liquid and solid / gas separation , filtration of oils , greases , water , fuels , paints , food products , liquid cooling agents , and chemicals etc.
1. It has high mechanical strength, can bear large pressure drop.
2. It has equal slots for filtering, can form equally distributed filter cake, easy to clean for reuse.
3. The wedge type slot can improve back flushing and regeneration performance.
4. It has resistance to pressure, temperature, aging, corrosion, can be applied for different kinds of fluid.
