1.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.
2.The single-slot staggered, longitudinal pattern is generally preferred because the strength of
the unslotted pipe is preserved.
3.The staggered pattern also gives a more uniform distribution of slots over the surface area of the pipe.
4.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.
Material: carbon steel, stainless steel Pipe
categories: oil casing, tubing;
Length (single) : 15 m or less;
Pipe diameter: 50 to 500 mm (length of 15 m or less)
Wall thickness: 20 mm or less;
Slot width (0.10 ~ 4) mm + / - 0.03 mm;
The slot layout: parallel, crisscross, spiral
1.The slotted liner is mainly used to the water and oil reservation layer without much sand.
2.Its function is to prevent the rock bits dropping into the well bore.
3.The working principle is allowing the certain size sand coming through the surface with crude
oil but keeping the bigger size sand being stopper outside to form sand bridge,and thereby
achieving the anti-sand purpose.
4.This type of product is commonly used to sand rock and carbonate reservoir,and especially
useable for horizontal wells.
