Slotted casing pipes
Steel slotted pipes used in deep bore wells, oil wells;
During oil drilling, the production of sand from the oil layer will reduce the output of the oil well. The slotted pipe is an important tool for sand control, and it is often used for early completion or oil production to prevent sand. The slotted pipe screen is a high-strength alloy steel casing that cuts gaps distributed according to a certain rule. The slit cross-sections are mainly rectangular and trapezoidal.
Compared with traditional mechanical processing methods, trapezoidal slots and curved slots can be precisely formed. The slot can reach 0.1mm, and the gap width is regular, there is no slag in the gap, and no secondary processing is required. It has the advantages of high processing precision, high processing efficiency, and wide processing range.
The production range of slotted screens is as follows:
OD: diameter from 25mm to 900mm
Slot size:
The minimum slot width is 0.15mm;
The minimum slot length is 5mm;
Other sizes are all according to customer requirements;
Opening area: Utmost 60%.
Material: Low carbon steel, low carbon steel galvanized, stainless steel (304, 304L, 316, 316L etc.)
