Abundant water shall reduce the water level’s down, thus to save energy consumption.ģ. Low cost operation Screens with high open area shall favor groundwater infiltration. Screens with high open area are more suitable for the construction of high-quality water wells, oil wells and gas wells.Ģ. unit length: we suggest 2.9m or 5.8m, to fit the container.ġ. connection types: usually stc threads or a passage of welded ring (plain end or beveled end), both of them are welded together with the portion of screen.ħ. wire and rod dimensions: obtained through well depth, or collapse strength and tensile strength, which are furnished by customers.Ħ. open area: a maximum open area of 60% is offered facilitating high flow capacity and low inlet resistance resulting in extended well life.ĥ. material: carbon steel or stainless steel(201,304,304l,316, 316l and so on)ģ. Regarded as the best choice of well tube filter, they are widely applied in a variety of fields in the developed countries.ġ. Typically the slots are punched in a flat sheet that is subsequently rolled into a tube and welded. Slotted Wedge Wire Screen is also called flower tube, it has the bridge openings arranged in rows and are staggered to reduce the negative effect on the screen’s strength.
