Description

Bridge Slotted Screen Pipe
Bridge slot screen have bridge opening arranged in rows and are staggered to reduce the negative effect on the screen's strength. Typically the slots are punched in a flat sheet that is subsequently rolled into a tube and welded. Regarded as the best choice of well tube filter, they are widely applied in a variety of fields in the developed countries. According to our after-sale services and the application experience at home and abroad, the advantages of bridge slot screens. When compared with other kinds of screens, can be listed as follows:

High strength through resistance to twisting, compressive, and tensile forces. A smooth bore that does not impede the passage of probes, tools, etc.
The special structure of the slot makes it difficult for particles to get stuck in the slot, thus bettering its discharge capacity.
The special bridge slots of screens help improving their mechanic strength.
Application of anticorrosive coasting will prolong the span lift of wells.
Slots and the diameter of bridge slot screens can be custom made to satisfy your needs.
Convenient to operate owing to various connecting methods between screens.
Lighter in weight and lower in price.

Choice Of Material and Anticorrosive Coating Of Bridge Slot Screens

In the ordinary course of events, we choose galvanized or coated Q235(A3) carbon steel of stainless steel.
Anti-corrosive coating and anti rust coating are available in accordance with the requirements of customers.
Precautions When Laying the Screens

Checking the intensity of screens.
Preventing screens from colliding with hard substances.
Laying screens slowly and evenly.
Suspensory Screen-laying Methods

1- Steel Wire Ropes
2- Linking Sheaths
3- Casing plywood
4- Slot screen
5- Square Lumber
Optimum Exploitation Flow

Bridge sloth screens increase its flow to three to nice times, when compared with other kinds of screens with the same slot width, diameter and length.

Lower Water Price

Water wells, when using bridge slot screens, can easily adjust themselves to aquifer and are regarded as a profitable mode of obtaining water:

Reducing the water velocity (V1>V2)
Reduction of pressure fall
Reduction of the head Loss (R1>R2)
Higher flow rate (HMT1>HMT2)
No sand in the water
Prolonging the life span of pumps
Adopt the suspensory screen-laying method.
Carefully check whether screens become deformed before laying them down, and adjust them when necessary.
Default slurry before laying down screens with the proportion of less than 1.2T/M3, otherwise, the blocking of slots will produce great pressure difference inside and outside the screens, leading to the possibility of deformation. Similarly, the use of nylon net will cause the deformation, therefore great pressure difference should be avoided.
Lay down screens steadily. If not smoothly, adjust the angle of screens and check whether they are deformed as a result of blocking before trying again. If screens cannot be lain down on account of blocking, forcibly trying should be forbidden.
Generally, compressors are used to flush wells, when pistons are necessary, operating pistons should be careful in case of the deformation of screens as a result of great pressure difference caused by the violent operation of pistons.
No clogging Water-carrying Section

Special construction of bridge slot screens make it possible to keep grains of sand it or screens, thus changing the direction of water flow and lessen its resistance.
