الوصف

Non-magnetic drill collar is made by special low carbon steel alloy, which is picked by strict analyses as to make rigidity, ductility, stroke resistance and corrosion resistance in according with API standards. It have good magnetic permeability and mach inability.

Relative permeability (intensity of magnetic field=1× ***4π Nm)
Max.: 1.*****1/8"****3/4"
AV.: Mr ≤ 1.**5
Field gradient: B ≤ 0.*5µ T
We produce various of non-magnetic drill collar (**1/8"****3/4").
