Features
It has good low permeability and high strength. Excellent mechanical properties, excellent intergranular corrosion resistance, crack resistance and wear resistance.
Advantages
Since all magnetic measuring instruments sense the borehole's geomagnetic field when measuring the direction of the borehole, the measuring instrument must be in a non-magnetic environment. However, in the drilling process, the drilling tool is often magnetic and has a magnetic field, which affects the magnetic measuring instrument and cannot obtain the correct wellbore trajectory measurement information data. The use of a non-magnetic drill collar can implement a non-magnetic environment and has the characteristics of a drill collar during drilling .

Introduction
The non-magnetic drill collar is made of low carbon high chromium manganese alloy steel. It is refined by strict chemical composition, and its mechanical properties are obtained through forging. When the magnetic field strength is 1×105/4marea/m, the relative permeability bias of non-magnetic drill collars is r≤1.010. The magnetic induction intensity gradient of non-magnetic drill collar at any interval of 100mm along the inner hole≤0.05
Non-magnetic drill collars have unusual design requirements, and as a result pose unique problems of corrosion resistance. Drill collars are the bottom components in a drill string, where their weight generates the force on the drill bit allowing it to drill and their stiffness allows the force to be transmitted without buckling. Conventional drill collars are made of alloy steel, like the rest of the drill string, and their corrosion usually poses no problems except to their threaded connections. A typical drill collar is 30 feet long and 4 to 9 inches in diameter.
Used in
Pipeline transportation, boiler tube, hydraulic/automotive tube, oil/gas drilling, food/beverage/dairy products, machinery, chemical industry, mining, building decoration, special purpose.
