WELL SCREEN (WATER FILTER)

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.1. PRODUCTION PROCESS CONTINUITY: V-SHAPED PROFILE WIRES CREATING SLOTS WHICH ENLARGE INWARDLY AND THEREFORE AVOID CLOGGING AND MINIMIZE DOWNTIME.2. LOW MAINTENANCE COSTS: SEPARATION AT THE SCREEN SURFACE WHICH CAN EASILY CLEANED BY SCRAPING OR BACK WASHING.3. MAXIMUM PROCESS OUTPUT: PRECISE AND ConTINUOUS SLOT OPENINGS RESULTING IN ACCURATE SEPARATION WITHOUT LOSS OFF MEDIA4. LOW OPERATIonAL COSTS: LARGE OPEN AREA WITH AN EFFECTIVE FLOW, HIGH YIELD AND A LOW PRESSURE DROp5. LONG LIVE: WELDED AT EACH INTERSECTIONS CREATING A STRONG AND DURABLE SCREEN.6. REDUCED INSTALLATION COSTS: SUPPORTING ConSTRUCTIONS ELIMINATING COSTLY SUPPORT MEDIA AND ENABLING A MAXIMUM FLEXIBILITY IN THE DESIGN OF COMPONENTS7. 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 THE SPECIAL SHAPE OF THE WIRE USED TO FORM THE SCREEN SURFACE. THE V-SHAPNED OPENINGS, DESIGNED TO BE NonCLOGGING ARE NARROWEST AT THE OUTER FACE AND WIDEN INWARDLY.CONTINUOUS-SLOT SCREENS PROVIDE MORE INTAKE AREA PER UNIT AREA OF SCREEN FURFACE THAN ANY OTHER TYPE. FOR ANY GIVEN SLOT SIZE THIS TYPE OF SCREEN HAS MAXIMUM OPEN AREA. 技术范围筛管尺寸 内径 外径 母螺纹外径in mm In mm in mm In mm2 51 2 51 25/8 67 23/4 703 76 3 76 35/8 92 33/4 954 102 4 102 45/8 117 43/4 1215 127 5 127 55/8 143 53/4 1466 152 6 152 65/8 168 7 1788 203 8 203 85/8 219 91/4 23510 254 10 254 103/4 273 113/8 28912 305 12 305 123/4 324 133/8 34014 356 131/8 333 14 356 — — 16 406 15 381 16 406 — — 20 508 18 3/4 476 20 508 — — 　PROFILE WIRE 　WIDTH(mm) 1.50 1.50 2.30 2.30 1.80 3.00 3.70 3.30　HEIGHT(mm) 2.20 2.50 2.70 3.60 4.30 4.70 5.60 6.30　SUPPORT ROD ROUND　WIDTH(mm) 2.30 2.30 3.00 3.70 3.30 Ø2.5--Ø5mm　HEIGHT(mm) 2.70 3.60 4.70 5.60 6.30 ----SLOT SIZE(MM): 0.10, 0.15, 0.25, 0.30-3, ALSO ACHIEVED UPON CUSTOMER REQUEST.OPEN AREA UP TO 60%MATERIAL: LOW CARBON, LOW CARBON GALVANIZED STEEL(LCG), STEEL TREATED WITH PLASTIC SPRAYING, STAINLESS STEEL (304, 316,ETC)LENGTHS UP TO 6METERSDIAMETER RANGING FROM 25MM TO 1300MMEND CONNECTION: PLAIN BEVELED ENDS FOR BUTT WELDING OR THREADED
