Johnson Stainless Steel Wire Wrapped Screen For Water Filtering Industry
The Continuous slot wire wrapped screen is made of V-shape wire or wedge shape wire around an internal array of longitudinal support rods. Each joint point of these wire is fusion welded, the V or wedge shaped profile wire wraps around the support rods over the full length of the screen creating a continuous slot opening. Therefore the screen allows water or oil to enter the well freely in ample quantities while keeps the majority of sand and gravel out of the well at the same time.
Continuous slot: support rods and longitudinal wire makes an opening which significantly increase the available opening area, and allow better access to the water flow.
High open area: reduce the water level, thus to save energy consumption. Meanwhile, high open area can make the groundwater enter the screen much slower than other filtration apparatus, which can avoid sand from entering screen due to high pressure, hereby lowering pump wear down.
High Strength: It takes stainless steel as main raw material, then is welded at high temperature, which guarantee high strength to bear big water pressure, hereby it has long life span.
Product Description:
Wire Wrapped Johnson Screen is welded by V wire and support rod.
There is a fixed value slot between each v wire, and the continuous slot, designed to provide maximum open are to reduce entrance velocity, increase hydraulic efficiency and promote more effective development. The wrapped wire is V shape, and the support rod is O shape. Filter from outside to inside.

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 numerical control 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
Use:
The wire wrap Johnson screen pipe can be widely used in petroleum gasoline industry and the prevention of sand in water well, chemical industry and environment protect industry. Especially in water filtering industry, it has the prominent position.The Johnson screen pipe can be widely used in petroleum gasoline industry and the prevention of sand in water well, chemical industry and environment protect industry.
