length:≤12m (each)
outside diameter :50-500mm

slot space:as per customer's requirement
slotted casing with apertures of 0.20-6mm are wide used in prevention of oil and wells
1. The slotted pipe is suitable for the sand particle size is greater than 0.3 mm of sand sand control well.
2. Cutting edge verticality, trimming smooth, without burr, cutting evenly.
3. The flow area is large, 27/8 "screen 300 slot / 1.5 m, 2.4 times larger than pipe flow area of the same specification.
4. The overall anticorrosive processing, improved the sieve tube corrosion resistance and wear resistance, can prolong the downhole working life.
5. The slotted tube adopts J55 and N80 oil casing processing, high strength, not easy to deformation.
6. The size is big, easy to pipe operation
The minimum slot width that can be achieved is about 0.012 in. Slots that cut less than 0.020 in. in width involve high costs
because of excessive machine downtime to replace broken saw blades that overheat, warp, and break.
The single-slot staggered, longitudinal pattern is generally preferred because the strength of the unslotted pipe is preserved.
The staggered pattern also gives a more uniform distribution of slots over the surface area of the pipe.
The single-slot staggered pattern is slotted with an even number of rows around the pipe with a typical 6-in. longitudinal spacing of slot rows.
