Wedge Wire Screen is widely used as well screen for groundwater and sand control applications. The V wire screen offers high strength, clog-resistant flow and precise filtration, ideal for deep well drilling, groundwater extraction and sand control in oil and gas wells.
Wedge wire well screens are available in stainless steel 304, 316L, or custom alloys.
Features:
- Continuous Slot Structure
The V-shaped profile wire creates a continuous slot that allows water to enter the well freely while keeping sand and fine particles out. - Non-Clogging Design
The outward widening slot prevents clogging by allowing particles to pass along the surface rather than getting trapped, reduces maintenance and prolongs the life of the well. - High Mechanical Strength
The welded screen construction is resistant to external pressure and collapse, ideal for deep well installations. - Corrosion Resistance
Typically made from 304, 316L, or Duplex stainless steel, wedge wire well screens resist corrosion from groundwater, seawater and chemical exposure.

Technical data
Well screen
- Screen openings shall be uniform in size and pattern, and spaced approximately equally around the circumference of the pipe.
Stainless Steel Well Screen
- The well screen and fittings are fabricated entirely from stainless steel conforming to ASTM A312/A312M, Type 316 or 316-L, resistant to oxalic acid used to treat wells for iron bacteria. The well screen is of stainless steel with a rod-based keystone vee wire-wrapped continuous slot strainer equivalent to that manufactured by Johnson Screens. The well screen, pipe, and fittings have a minimum collapse strength of 90 psi. The screen, pipe, and fittings shall have a clear inside diameter of 7-7/8 inches.
Couplings
- Couplings for the stainless steel well screen shall consist of the same material as the well screen and shall be threaded, flanged, and/or fitted with a beveled welding ring. The couplings shall conform in design to the couplings recommended by the manufacturer of the well screen.
Perforations
- The 8 inch diameter well screen shall have a number 20 slot, 0.020 inch open slot. There shall be a total opening of not less than 60 square inches per foot of 8 inch diameter well screen.
Riser Pipe
- The relief well riser pipe material shall conform to the requirements specified for WELL SCREEN.
- The relief well riser pipe diameter and discharge details shall be as specified.
- Couplings to the well screen and between riser pipe sections shall be as specified.
- If the riser pipe is attached to the well screen by welding, the riser pipe shall be beveled to match the angle of the welding ring of the screen section.
Filter Pack
- Material for the filter pack around the riser pipes and screens shall be a dry processed sand composed of hard, tough, and durable particles free from adherent coating.
- The filter pack shall not be crushed stone.
- The filter pack material shall contain no detrimental quantities of organic matter nor soft, friable, thin, or elongated particles in accordance with the quality requirements in ASTM C33/C33M, Table 1 and Table 3, Class 5S, and in ASTM E 11, Table 1.
