Spiral Non Magnetic Drill Collars

Non Magnetic Drill Collar Spiral Drill Collars For Oil Field Equipment

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 the non-magnetic drill collar r≤1.010. Magnetic induction intensity gradient of non-magnetic drill collar at random intervals of 100mm along the inner hole ≤0.05
Non-magnetic drill collars have unusual design requirements, thus creating unique corrosion resistance issues. The drill collar is the bottom part of the drill string. Its weight generates a force on the drill bit, which enables the drill bit to be drilled out, and the rigidity of the drill collar prevents the transmission of force from buckling.

Features
It has good low permeability and high strength. Excellent mechanical properties, excellent intergranular corrosion resistance, crack resistance and wear resistance.
