0.5mm Slot Well Screens BTC ends connection of Johnson screens:
Continuous wire wrap screen:
screens were already developed and in use in the U.S. about 90 years ago. This design makes it possible to adjust the slot width with minimum tolerances to the characteristic grain-size distribution curve of the respective aquifer and manufacture the slots in such a way that an optimal sand removal from the adjoining natural rock is possible.
Short delivery times
Manufacturing in compliant to DIN 4935
The welded stainless steel wedge wire screen is made up of rods and profile wire.
The rod can be round wire, triangular wire or trapezoid wire. The profile wire is triangular wire (V-shaped wire).
This type of wedge wire screen has a structure and high open area, as well as accurate slot dimension.
The wire is attached to the rods by welding, producing rigid one-piece units having high strength characteristics at minimum weights.
Features & Benefits
1. V-Shaped Slots — Openings shaped like a “v” that open toward the inside of the well tend to allow the particles that are just barely smaller than the width of the slot pass. In other shapes of openings, these particles would get caught in the screen and clog it.
2. Very Large Open Area — This design gives continuous slot and hence the open area for water to enter is more than 2 times that of conventional slotted pipes of any size and slot opening. This allows more water to enter at much lesser frictional head loss and the efficiency of tube well is improved appreciably.
3. Low maintenance costs — Separation at the screen surface which can easily cleaned by scraping or back washing.
4. Maximum process output — Precise and continuous slot openings resulting in accurate separation without loss off media.
