9 inch Wire-wrapped Casing Screen

Products Introduction about  Johnson water well screen,
Its' material is stainless steel
The profile wire wraps around internal array of longitudinal support rods.
Each intersecting point of these wires is fusion welded.
The profile wire wraps around the support rods over the full length of the screen creating a continuous slot opening
So the screen can allow water and oil to enter the well freely.And at the same time,it keeps the majority of the sand and gravel out of the well.
The length and the thickness are according to the customers' requirements.
 
Meanwhile ,our company can offer a whole set of service,such as the related process,the solution of the related technology and so on.

Compared with other Ordinary pipes(cement pipe,silent stock tube,ect)
1.  V wire wrap water well screen  with high open area are more suitable for the construction of high-quality water wells, oil wells and gas wells. 
2. Low cost operation       
V wire wrap water well screen with high open area shall favor groundwater infiltration. Abundant water shall reduce
the water levels down, thus to save energy consumption.
3. Reduce the abrasion of the pump  
4. Extend the life span of wells
5. Fixed tube and Protection Wells
Slot width shouldn't exceed 0.02mm and shouldn't less than 0.01mm compare to standard size when slot width is below 0.2mm
Slot width should be controlled within ± 0.02mm compare to standard size if slat width is bigger than 0.25mm
Plating 
Hard plating the wedge bar surface, plating thickness is 0.20-0.30mm. surface hardness >HRC : 60-66 (HV700-900)Product structure : wedge wire screen and stainless steel pipe
USES
The strainer is a kind of filtered water tubing with the perforation .it can use with the deep well pump, dive the water pump, also may use in the water-treating equipment, the environmental protection, the sea water transforms into the industrial water and life use water desalination treatment, running water treatment, water softening treatment, the petroleum industry: The petroleum product terminal filters and the chemical acid, the alkali liquid filters, the ethyl alcohol and so on the organic solution recycling filters.
