Characteristics of non-magnetic drill rods
release time：2024-04-15
source： network
Non magnetic drill pipe is a special equipment that can safely and efficiently drill in magnetic environments. It has the following main characteristics:
1. Non magnetic: The main characteristic of non-magnetic drill rods is their non-magnetic properties, with extremely low magnetic permeability, usually ≤ 1.005. This characteristic enables the non-magnetic drill rod to effectively prevent interference from magnetic fields during the drilling process, thereby ensuring the measurement accuracy of the measurement system.
2. High safety performance: Non magnetic drill rods do not produce sparks during impact and friction, greatly improving work safety.
3. High tensile strength and torsional performance: Non magnetic drill rods have a tensile strength of ≥ 1035MPa and a yield strength of ≥ 965MPa, which enables them to maintain good stability in complex drilling environments.
4. Good plasticity: The fracture elongation of non-magnetic drill rods is 2-5 times that of beryllium copper, which can fully reach the level of 135 steel grade. This means that non-magnetic drill rods can better maintain their shape and structure when subjected to external forces.
5. Strong corrosion resistance: Non magnetic drill rods have strong corrosion resistance and adaptability to underground environments, and can operate in acidic and highly corrosive environments with hydrogen sulfide, greatly extending their service life.
The characteristics of non-magnetic drill rods have made them widely used in geological exploration, directional drilling in coal mines, and other fields. By accurately obtaining geological data and avoiding the influence of magnetization effects, non magnetic drill rods provide an efficient and safe solution for drilling work.
