Pipe-based water well screens combine the hydraulic efficiency of wire-wound screens with the great strength of pipe.The base pipe is perforated or slotted API casing pipe,the base pipe can be stainless steel or carbon steel API 5CT casing.The all-welded wedge wire screens are welded together with base pipe by supporting rod. The Johnson pipe based screen is recommended when high collapse resistance is required and when the screens’ length generates a high longitudinal constraint. The pipe strength allows smaller wrap wires to be used, yielding greater open area.
a. Screen size or OD: depends on the downhole diameter and pump size.
b. Material: decided by the PH value of water.
c. Slot size and perforated size: according to the water flow and gravel size.
d. Collapse strength and Tensile strength: depends on the depth of screen will be installed to.
e. Connection: Thread ends(pin and box ends).
f. Unit Length: range length like R1,R2,R3, or fixed length of 5.8m.
g. Packing: inner packing of bubble bag/woven bag and out packing with wood strips.
