This type of screen made up of rods and warp, the rod can be round wire,triangular wire and trapezoid wire.The wire is welded to the rods and produces a rigid unit that has high strength and minimum weight.The warp is triangular wire(v-shape wire).The straight looped wedge wire have a structure and high open area;as well as accurate slot dimension.Johnson filter screen stainless steel wire have heat -resistant,anti-corrosive,good machine capability,last long ,safety and reliability and so on.
When compared to conventional slotted pipe, Water Well Screens have superior open area due to their continuous slot openings. The benefits of which will :
Reduce energy consumption and increase water flow.
Reduce erosion of entry surfaces and increase well life.
Allow a uniform and efficient well development.
Reduce significantly potential pump damage and subsequent maintenance costs.
A continuous slot opening which significantly increases the available open area, thus providing greater access to the water bearing zone (the aquifer)
A "V" shaped profile wire which avoids clogging and ensures an uninterrupted flow.
A uniform and efficient well development due to the continuous slot opening.
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.
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.
