Slotted screen pipe for drilling
1) Slot steel pipe screens are often the best choice for use in unconsolidated sand and gravel aquifers
2) They are constructed by winding and attaching a triangular strand of wire around a set of vertical rods
1) The slotted liner is a robust and cost-effective solution for long completions or low productivity wells
2) We offer straight and keystone slot types in the wide range of slotting patterns to create the required open area

Product Description
Slotted liners are made from tubulars by saw-cutting slot configurations, as shown in follow picture Slot widths are often referred to in terms of gauge. Slot or screen gauge is simply the width of the opening in inches multiplied by 1,000. For instance, a 12-gauge screen has openings of 0.012 in.

The slots can be straight or keystone shaped, as illustrated in following picture, The keystone slot is narrower on the outside surface of the pipe than on the inside. Slots formed in this way have an inverted "V" cross-sectional area and are less prone to plugging because any particle passing through the slot at the outside diameter (OD) of the pipe will continue to flow through, rather than lodging within the slot. While the slotted liners are usually less costly than wire-wrapped screens, they have smaller inflow areas and experience higher pressure drops during production. Slotted liners also plug more readily than screens; they are used where well productivity is small and economics cannot support the use of screens.
