Description
Wedge Wire Screen Cylinders are also named Johnson Screen Pipe/tube,slotted wedge wire filter cylinders.They are welded by the surface wire winding support rod.In order to solve the problems of poor roundness and uneven gap in domestic wire gap filter,our company has purchased international advanced welding equipment for wire gap filter element.The welding wire wound filter element (wire gap) has excellent roundness,the minimum gap is 15 μ m,the negative tolerance is 5 μ m,the minimum diameter of the welded wire gap filter element is 25.4mm,the maximum is 2000mm,and the raw materials used are all imported to ensure our products Whether from the origin of raw materials,or wire processing technology,can meet international standards.
