wire-wrapped stainless steel screen pipe

Description

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.
　　　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.
