How to find proper screen dimensions and correct slot sizes of the wedge wire screens
Diameter
Specific capacity and available drawdown indicate the productivity of awell to be expected.
If the pump is installed above the screen the rising velocity at the screen head should not exceed v= 1.75 meter/sec.
If the pump is installed below the screen in apump sump then the screen diameter depends mainly on the pump size and the remaining annulus space between the screen and the riser pipe.
Screen length
once decided on the screen diameter the laminar flow conditions at the entrance of the screen determine the requested length. Screen length in the total height of awater bearing formation is -especially when using the con-slot screen -not necessary. The Kozeny concept of investigation for partial penetrated formation is an excellent practice to determine max. Necessary screen length.
RFQ:
If you are satisfied with ourDuplex 2205 stainless steel Johnson Wire Wrapped screensand willing to know precise price and more information, the following questions is appreciated:
1, What's the material you are going to deal with, stainless steel 304,304L,316 or 316L?
2, What's the OD, length? Diameter from 4-914mm,length from 0.1-12m
3, What's the depth of the well or tensile strength of the casing pipes that you need?
The tensile strength is important for the screens and each screen will be tested before delivery.
4,The connection type that you need? thread or flange?
