FOR WATER, OIL, AND GAS WELLS, AND IS THE DOMINANT SCREEN TYPE USED
IN THE WATER WELL INDUSTRY.
　　　FEIYA CONTINUOUS-SLOT WELL SCREEN IS MADE BY WINDING
COLD-ROLLED WIRE, APPROXIMATELY TRIANGULAR IN CROSS SECTION, AND
ROUND A CIRCULAR ARRAY OF THE LONGITUDINAL RODS. THE WIRE IS
ATTACHED TO THE RODS BY WELDING, PRODUCING RIGID ONE-PIECE UNITS
HAVING HIGH STRENGTH CHARACTERISTICS AND MINIMUM WEIGHTS.
　　　SLOT OPENING FOR CONTINUOUS-SLOT SCREENS ARE MANUFACTURED
BY SPACING SUCCESSIVE TURNS OF THE OUTER WIRE TO PRODUCE THE
DESIRED SLOT SIZE. ALL SLOTS SHOULD BE CLEAN AND FREE OF BURRS AND
CUTTINGS.
EACH SLOT OPENING BETWEEN ADJACENT WIRES IS V-SHAPED, FROM THE
SPECIAL SHAPE OF WIRE USED TO FORM THE SCREEN SURFACE. THE V-SHAPED
OPENINGS DESIGNED TO BE NONCLOGGING, ARE NARROWEST AT THE OUTER
FACE AND WIDEN INWARDLY. TEHY ALLOW MORE FLOW.
PRODUCTION PROCESS CONTINUITY: V-SHAPED PROFILE WIRES CREATING
SLOTS WHICH ENLARGE INWARDLY AND THEREFORE AVOID CLOGGING AND
MINIMIZE DOWNTIME.
LOW MAINTENANCE COSTS: SEPARATION AT THE SCREEN SURFACE WHICH CAN
EASILY CLEANED BY SCRAPING OR BACK WASHING.
 MAXIMUM PROCESS OUTPUT: PRECISE AND CONTINUOUS SLOT OPENINGS
RESULTING IN ACCURATE SEPARATION WITHOUT LOSS OFF MEDIA
LOW OPERATIONAL COSTS: LARGE OPEN AREA WITH AN EFFECTIVE FLOW, HIGH
YIELD AND A LOW PRESSURE DROP
 LONG LIVE: WELDED AT EACH INTERSECTIONS CREATING A STRONG
AND DURABLE SCREEN.
 REDUCED INSTALLATION COSTS: SUPPORTING CONSTRUCTIONS
ELIMINATING COSTLY SUPPORT MEDIA AND ENABLING A MAXIMUM FLEXIBILITY
IN THE DESIGN OF COMPONENTS
 CHEMICAL AND THERMAL RESISTAN. A VARIETY OF CORROSION
RESISTAN STAINLESS STEEL MATERIALS AND MANY EXOTIC ALLOYS SUITABLE
FOR HIGH TEMPERATURES AND PRESSURES.
EACH SLOT OPENING BETWEEN ADJACENT WIRE IS V-SHAPED, RESULTING FROM
