wedge wire well screen

Wire Wrapped Screen is manufactured by wrapping a shaped wire around an internal array of longitudinal rods. The wire and rod, generally made from carbon or stainless steel are joined by resistance welding. Screen sections are usually twenty feet long. Commonly referred to as continuous slot or wire wrap screen,this product was originally developed to overcome problems associated with cable tool wells drilled in fine grained, uniform sands in the North Central United States. These wells were typically completed in relatively shallow upto 1000 meter depth, thin aquifers that were very prolific in terms of water production. Continuous slot screens are very effective in wells of this type since they can be manufactured with very small slot size and yet still maintain the necessary open area to minimize frictional head loss. Most continuous wire wrap screen is manufactured from stainless steel 304L,the wire wrapped screen specitication rangs are as per the following.

The slot size width range is from 0.15 mm to 3 mm.

The collapse pressure is from 50 PSI to 3500 PSI.

The traction is up to 30 tons.

The opening area is up to 30%

The end fitting can be weld rings, threaded connection-.etc.
