The consecutive slot have more open area, and it can reduce the speed of the water entering to avoid the sand entering the Water Well Screens under the great pressure, so it can filter sand better. Meanwhile, the slot of Water Well Screens can change according to the real condition of the earth.
Specifications of SS304L Wedge Wire Continuous Slot Water Well Screens:
1.Material: stainless steel (304,304L,316,316L etc.)

3.Slot Size (mm):0.3, 0.5, 0.75, 1 or as per customers’ requirement
4.Unit length up to 6m, 5.8m fit for the container
5.Open area 33%
6.End Connection:Welding (beveled end), thread coupling(STC,LTC,BTC) or flange
7.Surface treatment:Galvanized, painted, polish, pickling & passivation,etc.
8.Packing:Bubble bag and woven bag, in bundle or unbundle or in wooden cases.
MAXIMIZING FLOW RATES
When considering screens of equal length, diameter and slot size, flow rates through V-shaped well screens can be;
Three times higher than bridge-slot screens
Nine times higher than slotted casing
Continuous-slot well screens have V-shaped openings that narrowest at the outer face and widen inwardly, thus, over sized particles are retained outside the screen and particles passing through the narrow outside opening can enter the screen.
REDUCTIONS IN OPERATING COSTS
By using a Continous-slot well screen, savings can be achieved in pumping costs. Lower through-slot velocities mean that pressure drops are minimized, therefore;
Drawdowns are reduced.
Less energy is needed for pumping.
Flow rates are increased.
Less sand in the water reduces wear on the pumps.
The continuous-slot well screen is widely used throughout the world for water, oil, and gas wells, and is the dominant screen type used in the water well industry.
1.The continuous-slot well screen is recommended in the following situations;
2.Water wells where gravel packs will be installed
3.Thin aquifers, where maximum open area is required
4.Formation comprised of small or fine particles
5.Small diameter wells

Stainless steel water well screen comprise of V-shape profile wire and the longitudinal help poles. Each meeting purpose of these wires is combination welded, so Water Well Screens has strong tightening and great mechanical property. The V-shape area plane can stay away from blockage and ensure the unrestricted water.
