1mm slot water well screen filter pipe manufactory
Continuous slot or wire wrap screen
Continuous wire wrap screen is manufactured by wrapping a shaped wire around an internal array of longitudinal rods and are joined by resistance welding. Screen sections are usually twenty feet long(5.8 meter). Most continuous wire wrap screen is manufactured from stainless steel rather than carbon steel in order to avoid problems which often lead to accelerated corrosion.
These wells were typically completed in relatively shallow, thin aquifers that were very prolific in terms of water production. Continuous wire wrap screen 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.
Johnson strainer well screen pipe for water wel / oil well drilling
the welded stainless steel water well screen is made up of support wire and filter wire. with the material of stainless steel 304,316,304l,316l.
the support wires can be round wires, triangular wires or trapezoidal wires, while the filter wires is triangular wires(v shape wires).
precise aperture size, high filter precision,firm structure, high-temperature resistance, corrosion resistance and mechanical performance is good,long service life, safe and reliable, etc. can be used in various media filtration and screening.
