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. Aokai Continuous-Slot Well Screen is made by winding cold-rolled wire, approximately triangular in cross section, around 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 at 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; they allow;

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 media.

4. Low operational costs: Large open area with an effective flow, high yield and a low pressure drop (dP)

5. Long live: Welded at each intersection 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 components.

7. Chemical and thermal resistant: A variety of corrosion resistant stainless steel materials and many exotic alloys suitable for high temperatures and pressures.Each slot opening between adjacent wires is V-shaped, resulting from the special shape of the wire used to form the screen surface. The V-shaped opeings, 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 surface than any other type. For any given slot size, this type of screen has maximum open area.




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 Filtration

  • Pulp and paper
  • Chemical
  • Petrochemical
  • Automotive
  • Mineral and aggregate processing
  • Plastics extrusion
  • Adhesive/sealant filtration
  • Coatings
  • Other highly viscous fluids in many industries

wedge wire filter elements are ideal for many challenging filtration applications. Our filter tubes provides:

  • Optimum structural strength for heavy loads
  • Minimal plugging and blinding
  • High pressure/pulsating pressure capability
  • Corrosive application suitability
  • Thermal resistance
  • Long-life - almost endless cleanability
  • Sterile application / food industry suitability
  • Low pressure drop
  • High flow rate

Liner Pipes & Well Screens

Liner Pipes
For 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.
Applications
Wells with medium or coarse sands

Key Features
  • Slots 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.

Slot Types 
Straight Mill Slotting
The slots of this slot type are of equal width throughout the wall of the casing, and therefore are more susceptible to clogging by sand from the formation than the Keystone slot described below. The slots are normally cleaned by hydro washing.
Keystone / Undercut Slotting
Trapezoidal 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 patterns
Slots 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.
