Product Description Wedge wire filter element also named wedge wire screen is made of V-shape profile wire and longitudinal support rods. Each intersecting point of these wires is fusion welded which makes it has sturdy construction and good mechanical property. The profile wire and support rod can be axial wire or radial wire. It mainly includes internal filtration, external direction filtration. According to the different usage, we can design the flow direction and shape to meet the application requirements. What's more, we can customized the wedge wire filter element such as filter tube, filter basket based on the clients requirements.Wedge wire filter element is widely used for deep well pump, dive water pump. Also used for waste water treatment, water softening treatment, oil industry, food process, mineral process, and chemical and alkali filtration. Industries That Can Benefit From Wedge Wire FiltrationPulp and paperChemicalPetrochemicalAutomotiveMineral and aggregate processingPlastics extrusionAdhesive/sealant filtrationCoatingsOther highly viscous fluids in many industrieswedge wire filter elements are ideal for many challenging filtration applications. Our filter tubes provides:Optimum structural strength for heavy loadsMinimal plugging and blindingHigh pressure/pulsating pressure capabilityCorrosive application suitabilityThermal resistanceLong-life - almost endless cleanabilitySterile application / food industry suitabilityLow pressure dropHigh flow rateLiner Pipes & Well ScreensLiner PipesFor all of our casing pipes we provide processing into liner pipes. High precision laser cutting ensures every slot is 100% up to specs. You can either provide a drawing or we will recommend a slot layout according to your individual requirements.Our liner pipes are especially cost-effective and of high quality due to imported equipment and technical expertise.ApplicationsWells with medium or coarse sandsKey FeaturesSlots are made on base pipes with a large ID/OD ratio.High mechanical strength, high flexibility to allow adequate bending, which makes the pipes applicable in complicated well conditions. Also used in open-hole horizontal well completion for sand control.Low manufacturing and down hole installation costs.Open hole area: 2%-6%.Base pipe: J55, N80, P110, etc.A continuous slot opening which significantly increases the available open area, thus providing greater access to the water bearing zone.High oil production rate due to a large filter area and low flow resistance.Uniform and efficient well development due to a continuous slot opening.Anti-acid, anti-alkali, and anti-corrosion. Cracks won't become larger because of corrosion.Easy backwashing, durable, safe and reliable use and cost effective.SpecificationsLength: ≤15m (each)Outside diameter: 50-500mmSlot width: (0.10-4)mm±0.03mmNumber of slots: As per customer's requirementsSlot shapes: Straight in line pattern, staggered pattern, spiral patternSlot space: As per customer's requirementsOut Diameter:4-1/2" - 20"lb/ft9.5lb/ft - 133lb/ftLengthR1.

The slots are normally cleaned by hydro washing.Keystone / Undercut SlottingTrapezoidal seam design making the outer surface of the slot wider than the inner surface, thus greatly reducing the chance of slot clogging clogging. Typically, the trapezoidal slot angle is designed to be 6°.Slot patternsSlots are either arranged in parallel or in an offset pattern. The offset pattern offers a better stability.Note: Please also take a look at our high quality sand screens.
