Stainless Steel 304/316 Water Well Wire Screen/Johnson Screen for Sand Control

Water well screen
Water Well Screens consist of V-shape profile wire and the longitudinal support rods. Each intersecting point of these wires is fusion welded, so Water Well Screens has sturdy constriction and good mechanical property. The V-shape section plane can avoid blockageand make sure of the unimpeded water.

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
NON-CLOGGING SLOT
Continuous-slot well screens have V-shaped openings that narrowest at the outer face and widen inwardly, thus, oversized 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.
