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

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

In oil drilling operation, slotted steel pipe is a very important tool for initial completion or sand production. The manufacturing process of this product is simple, cost effective and easy to control precision. Trapezoidal slot has self-cleaning effect which means that fine sand in the cavity can be washed away very easily, thus sand plug is prevented and flow pressure loss is significantly reduced. Round type has regular shape section and smooth edge, so oil recovery efficiency can be effectively improved. Parameters of the structure can be best designed by good combination so customers can make their choices on actual needs.
