Description
 
The wire-wrapped screen consists of perforated pipe, outer jacket, end ring and centralizer. Key-stone or house shape wires are simultaneously wrapped and welded to form uniform slots. The jacket is
then placed over perforated pipe and welded to each end. The KINGWELL wire-wrapped screen’s strength, high quality and precise slot control make it an excellent choice for deep, vertical wells as well as horizontal wells.
 
Advantages
 
 ● Key-stone shaped slot pattern, low risk to plugging, easy to clean;
 ● Superior resistant to corrosion and long lifespan in applications;
 ● Optimized design for perforation, all welded structure, high mechanical strength which is 
competitive with  casing of the same size;
 ● Minimum slot opening: 0.1mm, which can satisfy the most of well-completion requirements;
 ● High flow area;
 ● The technical is mature, good adaptability.
 
Application
 
Gravel-packing in cased-hole completions of vertical wells, directional wells, horizontal wells,
multi-lateral wells and open-hole completions.

Bridge Sloted Pipe
About Bridge Slot Screen
Bridge slot screen features bridge-like slot, which creates a gap between the well casing and the
packed gravel. Bridge slots are spaced in rows or in staggered state.
Bridge slotted screens are first punched in a flat sheet, which is completely CNC operated. The slot widths are  precise and can change as practical requirements. Then the flat sheet is subsequently
rolled and welded into a tube.
Bridge slot screen has extensive applications, including water and oil wells, development of
geothermal development and mineral water.
 
Application
 
This type of bridge slot screen pipe is used in projects of water wells, mining & Mineral Processing, municipal water supply, refining & petrochemical, water treatment, architecture and construction.
 
High Density Bridge Slotted screen
 
 ● The advanced spiral welding process and punching technology provides superior weld strength and accurate slot openings.The high density louvered pattern provides free flow and optimal sand control.
 ● The standoff from the louvers minimizes plugging and avoids damage during running and re-entries.
 ● The screen jacket is fully pickled and passivated for maximum corrosion resistance.
 ● The result is reliable and cost effective solution for sand free production in vertical and horizontal wells with gravel pack or coarse formation stand alone completions.
 
Features
 
 ● The SandFree BS Screen design provides
 ● Tensile, load, collapse strength
 ● Rotating ability during installation
 ● High corrosion resistance
 ● High density, accurate slot opening
 ● OD smaller than pipe couplings
 ● Uncomplicated installation
 
Customized design
 
The design is customized to your demands:
 ● Slot opening from 300 micron up to 2000 micron
 ● All API and ANSI pipe sizes are available
 
Customized construction:
 ● Screen thickness from 0,6mm up to 4,7mm
 ● Customized material grades Galvanized or Stainless 304/316L/Alloy 825 etc.
 ● Customized end-fittings and threaded connections
 ● Fixation of screen by welding or shrink fitting of end-rings to the base-pipe
 
Advantages
 
Bridge slot has outstanding anti-plugging performance for its unique bridge construction.
Bridge construction also enhances the mechanical strength against twisting, compressive and tensile forces.
Diverse external coatings are available to extend the operational lives of watering wells.
Bridge slot screen is lightweight and quite affordable compared with other conventional well screens.
Slot widths can be customized to satisfy customers’ specific requirements.
 
Materials
 
Bridge slot screens usually use low carbon steel Q235, stainless steel 304,304L, 316L. To prolong its service life, galvanized screens are still supplied.

erforated Liner
 
The Perforated Liner or Pre-perforated Casing is manufactured with a 44ft- 88-spindle Drill Press. Joints with sizes up to Ø 20”- length Range 3 and grades up to 13Cr110 are perforated in one handling.
Our standard spiral and staggered perforation patterns use Ø3/8” and ؽ”diameter holes, to create the required open area.
Upon request,custom hole sizes can be drilled in any number and any pattern.
 
Well Screen is deburred internal and external as well as drift tested according to API standards. Every hole is visually inspected and cleaned of burr material.
The size, grade and weight of the base- pipe are according to API casing or tubing specification.

Pre-packed Screen
 
The prepack design resists erosion where voids may exist in the pack. The prepack sand, typically resin coated and consolidated, can be provided in regular resieved sand varieties. All prepack screens are packed separately from the basepipe. This allows for inspection of the complete jacket for voids.
 
 ● Enhanced Low Profile (ELP) and Premium Low Profile (PLP) Prepack Screens — These screens can be used in gravel-packed and non-gravel packed wells. They incorporate a strong inner wire wrap layer made from round wire and a keystone-shaped outer wire wrap layer.
 
 ● Dual-Screen Prepack Screens — When gravel packing is not feasible, dual-screen prepack screens provide built-in sand control. They incorporate a keystone-shaped wire for the inner and outer wire wraps.
