Stainless steel wedge wire screen construction

Wedge wire screen diagram

Wedge wire screen, a rod-based wire wrapped screen features the largest open area compared with either slotted liner or pipe-based screen. Versatile wedge wire screens can be found in a great number of well applications, such as rude oil production, natural gas production, vessel internals and ground water exploration and so on.

Construction

Rods spaced evenly around the circumference support the screen and prevent the screen from deformation.

V-shaped wire produces self-cleaning action and non-clogging performance. The slot width on surface is increasing towards the internal side of the screen. This slot geometry is called keystone slot which has the ability of anti-plugging. Precise slot width should be designed to satisfy operation requirements. Usually, the slot width is two times the size of the formation sand.

End fittings can be customized to secure the screen body.

Materials

Wedge wire screens are usually fabricated by stainless steel 304 and 316L, low carbon steel, galvanized steel. However, optional temperature is another important element to be considered. So, wedge wire screens made of other materials are at stock, including Monel 400, Hastelloy (C4, C22, C276) and Inconel 600.

Bespoke design

Wedge wire screens can be manufactured into diverse slot widths and configurations depend on applications. Slot widths come in diverse sizes from 0.02mm (20 microns) to 10mm.

Custom wedge wire screens can be manufactured. Length, width, spacing of profile wire can be engineered to meet required service conditions.
