Casing & Screen Pipes :Longitudinal RIBSThe longitudinal ribs on the outer surface of the Ajay well screens, apart from imparting extra physical strength to the pipe, offer two positive effects.
- They combat the obstruction of slots by acting as spacer.
- They provide additional flow ways in the valleys bettween ribs, thereby, improving the hydraulic properties.
Horizontal SlottingAjay well screens have slots at right angle to the axis of the pipe which result in better callapse resistance and superior flow characteristics.Continuous slot well screenA screen superior to ordinary PVC slotted pipe supplied with very high percentage open areas specially designed for water wells.Added Advantages
- Lightweight easy to handle
- A maximum open area of 50 percents is offered facilitating high flow capacity and low inlet resistance resulting in extended well life.
- Screens are provided with threaded female ends and connected by means of separate nipple (adaptor) retaining length and internal and external smoothness.
- The hydraulic advantages afforded by screen make it also suitable for low yield water bearing strata.
- Advanced solid constructions suitable for installation to depths of 400 meters.
- Completely corrosion free eliminating electrolysis reaction.
