Johnson tube  called filter tube, wire and is supported by the V-shaped bar around, each crosspoint connection with welding mode, solid structure, good mechanical properties. V-shaped cross-section to avoid clogging, while ensuring the smooth flow of water. Continuous gap greater over the water area, while reducing groundwater infiltration rate, to avoid sand in the larger pressure into the tube, there is a better filter sand of the slit can also vary depending on geology.
Material: common steel blackboard, galvanized plate, stainless steel, copper, nickel plate, aluminum, resin panels.
Manufacturing: stamping by the punch through the die, the outer protective sheath may also spiral welded. Filter tubes may be made of stainless steel 304,316,316L, multilayer sand filtration kits and protection kits can be produced according to user needs.
1, multi-layer anti-sand filtration kits sand with efficient performance, better able to block the formation sand to meet the underground sand.
2, the filter pore uniform, high permeability and anti-blocking properties.
3, filter area, flow resistance is small.
4, stainless steel excellent corrosion resistance, acid, alkali, salt corrosion, can be adapted to the special requirements of wells, crevice corrosion and will not become bigger.
5, the multilayer structure welding can filter hole stability, resistance to deformation ability.
