Slotted Steel Pipe

SlottedSteel Pipe

Themanufacturing process of slotted steel pipe is to cut many vertical, spiralline or alternating slots on petroleum casing tube or oil tube. After that,special ultra-thin cutting discs and beam are usedand the width of slot is 2.5-0.5mm.The section is either rectangular, trapezoid with angle of 3-8 degrees andspecial shape such as circular. Permeability rate is 0.5% -10% and arrangement canbe customized. For types of slot, they are streamlined, alternating, doublealternating and double.

There are many features of slotted steel pipe. In the firstplace, it has high strength and resistance to deformation. In addition to that,it has good verticality ofedge, smooth edge, no glitches and uniform slot.Suitable to sand particle bigger than 0.3mm, it has easy operation, big innerdiameter and pipe string configuration

In oil drilling operation, slotted steel pipe is avery important tool for initial completion or sand production. Themanufacturing process of this product is simple, cost effective and easy tocontrol precision. Trapezoidal slot has self-cleaning effect which means thatfine sand in the cavity can be washed away very easily, thus sand plug isprevented and flow pressure loss is significantly reduced. Round type hasregular shape section and smooth edge, so oil recovery efficiency can beeffectively improved. Parameters of the structure can be best designed by goodcombination so customers can make their choices on actual needs.
