The 273mm water well screen pipe slot 1.0mm drilling water well screen tube are made from two elements the V-shaped wedge wire is helically wound around an array of internal longitudinal support rods. Each intersection of wire and rods is automatically resistance welded, creating a very strong cage-like cylinder with one continuous slot spiraling along its full length.
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, oversized particles are retained outside the screen and particles passing through the narrow outside opening can enter the screen.
By using a Continuous-slot well screen, savings can be achieved in pumping costs. Lower through-slot velocities mean that pressure drops are minimized, therefore;
Draw downs are reduced.
Less energy is needed for pumping.
Flow rates are increased.
Less sand in the water reduces wear on the pumps.
The 273mm water well screen pipe slot 1.0mm drilling water is widely used for the construction of the building of the hydrologic geology, Coal Geology, chemical, geological, geothermal air conditioning, foundation precipitation, water source development, urban water supply and other walks of life.
