Stainless Steel Johnson Water Well Screen, Deep Well Drilling Pipe

Stainless Steel Johnson Water Well Screen, Deep Well Drilling Pipe

•Product advantages:

1.Lower pumping costs

Water well screen have more open area than other screen types,which lets more water enter more easily.This creates less drawdown inside the well reducing the energy demand on the pump.

2.Less pump wear

Properly designed screens prevent sand from entering the well,preventing abrasion of pump impellors.The low entrance velocity also reduces sand pumping and head loss.

3.Longer well life

Because water enters the well easily,it can move at a low velocity-0.03m/s or less (0.01ft/s).Higher velocities create higher pressure drop or head loss,allowing gases to pass out of the solution,leading to encrustation of the screen surface. 

Continuous-slot screens provide more intake area per unit area of screen surface than any other type. For any given slot size, this type of screen has maximum open area.

•Our advantages:

Due to its high open area,our screens can be developed more effectively as more of the development energy can reach the formation.This ensures that more fine material is removed quickly as all the energy can be directed at the surrounding formation.

The continuous slot Vee-Wire screen is recommended in the following situations:

1.Formation comprised of small or fine particles

2.Water wells where gravel packs will be installed

3.Thin aquifers where maximum open area is required
