Backwash Wedge Wire Screen Filter

 The V-shaped wire can be made in different height and width to address various strength application, meanwhile, the spacing of individual slots can be varied during fabrication if geologic conditions require these variations in a screen's construction

Application for Bridge Slot Screen:

Used in industries such as Sugar, Coal Mining & Quarrying, Mineral Processing, Cement, and Industrial & Urban Effluent Treatment etc.
Used as a pre-filter in urban & industrial waste treatment plants to improve the performance of the clarifier by dramatically reducing the load.
Used for fiber removal in Starch industry.

Feature for Bridge Slot Screen:

1.The V-shape section plane of Wedge wire screen pipe (Johnson screens) creates the continuous slot, which can avoid blockage and make sure of the unimpeded water.
2. The consecutive slot of Wedge wire screen pipe (Johnson screens) have wider open area, and it can reduce the speed of the water entering to avoid the sand entering the screen under the great pressure, so it can control sand better, which can increase the water yield and prolong service time of the well.
3. Wire and support rods are all-welded, which makes the Wedge wire screen pipe (Johnson screens) more robust and longer life.
4. The longitudinal support rods and the continuous slot make the Wedge wire screen pipe (Johnson screens) have more excellent pressure-resistant performance.
5. Specifications and end connections of Wedge wire screen pipe (Johnson screens) can be fabricated according to customers’ requirements.

                        Application of Wedge Wire Screen Tubes


Wedge wire screen tube has a wide range of applications in the field of process, engineering such as sugar juice filtration, waste water treatment, crude oil and natural gas production and vessel internals solving problems of solid / liquid and solid / gas separation, filtration of oils, greases, paints, food products, water, fuels, liquid cooling agents, chemicals etc.

We can also make manufacture according to your detail specifications and we assure that we will give you the best services.



                                                  Advantages of Wedge Wire Screen Tubes


A continuous slot opening which significantly increases the available open area, thus providing greater access to the water bearing zone.

A “V”shaped profile wire which avoids clogging and ensures an uninterrupted flow.

A uniform and efficient well development due to the continuous slot opening.

Ladder-like wire welded screens have a strong structure and high open area, as well as accurate slot dimension.

5.Ladder-like wire welded screens have the features of easy backwashing, last long, safety and reliability as well as low comprehensive cost.

Bridge slotted screen a type of well screen with vertical slots that are formed by protruding "bridges"that are pushed outward from the well casing.
The sand and gravel can not easily block the slot because of the special bridge design. It has great mechanical strength and water entering capacity. Meanwhile, it use steel punching technology and rolled in many ways, so it is light, cheap and easily operating.
We use CNC to punch, so the slot can change as your requirements. In order to give customers more convenience, we can offer any diameter screens.We also offer galvanized ones to prolong the operational life.

Xingyun is specialized in producing and distributing wedge wire screen,lauter tun screens,sieve bend screen,sieve plate screen,water strainer&nozzle,screen nozzles,centrifuge screens and baskets,header-lateral etc.
