Continuous slot screen pipe - HD-W189

Continuous-slot well screen pipe
Application
The continuous-slot screen, widely used throughout the world for water, oil, and gas wells, is the dominant screen type used in the water well industry.
Production Methods
1. Winding cold-rolled wire, approximately triangular in cross section, around a circular array of the longitudinal rods.
2. The wire is attached to the rods by welding, producing rigid one-piece units having high strength characteristics at minimum weights.
3. Slot opening are manufactured by spacing successive turns of the outer wire to produce the desired slot size. All slots should be clean and free of burns and cuttings.
4. Process: for carbon steel screen, we can paint black lacquer or silver lacquer, or galvanized, stainless steel screen will be polished.
5. Package: inner bubble bag and outer woven bag. Wooden box can be employed if needed.
