Continuous slot screen pipe

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.

Specification Details: 1. OD(outside diameter): usually 6-5/8” 7” 8-5/8” 9-5/8” 10-3/4” 12-3/4”by our customers’ requirements. 2. Material: carbon steel or stainless steel(201,304,304L,316, 316L and so on) 3. Slot size: given by customers. We can do 0.05-2mm. 4.

Open area: a maximum open area of 60% is offered facilitating high flow capacity and low inlet resistance resulting in extended well life. 5. Wire and rod dimensions: obtained through well depth, or collapse strength and tensile strength, which are furnished by customers. 6.

Connection types: usually STC threads or a passage of welded ring (plain end or beveled end), both of them are welded together with the portion of screen. 7. Unit length: we suggest 2.9m or 5.8m, to fit the container. Any specific requirements, please write to us.
