  • V Wire Stainless Steel Johnson Screen Pipe - China

    price: contact company for price

    V wire Johnson screen

    The continuous slot wire-wrap screen is used throughout the world for water, oil, and gas wells, and for environmental well completions. It is the dominant screen type used in the water well industry. this type of screen is constructed by winding cold rolled triangular V-shaped wire around a circular array of longitudinal rods. the wire is welded to the rods and produces a rigid unit that has high strength and minimum weight.


    When considering screens of equal length, diameter and slot size, flow rates through V-shaped well screens can be;

    Three times higher than bridge-slot screens

    Nine times higher than slotted casing


    Continuous-slot well screens have V-shaped openings that narrowest at the outer face and widen inwardly, thus, oversized particles are retained outside the screen and particles passing through the narrow outside opening can enter the screen.


    By using a Continous-slot well screen, savings can be achieved in pumping costs. Lower through-slot velocities mean that pressure drops are minimized, therefore;

    Drawdowns are reduced.

    Less energy is needed for pumping.

    Flow rates are increased.

    Less sand in the water reduces wear on the pumps.
