6" Low Carbon Galvanized Continuous Slot Screen For Sand Control In Deep Well

Product Description:

Continuous Slot Screen, also be named Wire Wrap Johnson Screen,Johnson screen,Wound Screen, Wedge wire screen, Wire wrapped screen.

Continuous Slot Screen is of the continuous slot,designed to provide maximum open are to reduce entrance velocity, increase hydraulic efficiency and promote more effective development.Both the inner and outer screens shall be constructed of V-shaped wire continuously wrapped around an array of equally spaced support rods of the same material.Each junction of wire/rod contact shall be resistance welded.

Advantages:

Not easy to jam

the special V shaped wire, make the hole of screen outside face is smaller than inside, so the hole is not easy to jam.

Slot even

The CNC machine tools strictly control the gap between the wire, so that the gap is even.

Strong corrosion resistance

Stainless steel 304 have the high corrosion resistance

Application:

Continuous slot screen is best applied in the following situations:

Geological formations comprised of small, fine particles
Water wells where gravel packs will be installed
Thin aquifers, where maximum open area is required
Large- and small-diameter deep wells
