wedge wire water well screen pipe for liquid filtration

Wedge wire water well screen pipe , also called round slot tube. It is made of stainless steel wire, which is the most popular type because of outstanding chemical stability and corrosion resistance.

The wedge wire water well screen pipe  is composed of working profile and support profile. It is produced on an automotive machine. The support profiles is placed on the suit position of the machine, during the surface profiles are spirally wounding, the support profiles are welded onto the surface profiles.

Construction of wedge wire water well screen pipe for liquid filtration

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.

Feature of wedge wire water well screen pipe for liquid filtration

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.

Advantages of wedge wire water well screen pipe for liquid filtration
