The drilling Centralizers stabilizer is an essential part of full hole; pendulum and increase the stability decrease the incline in drilling
assembly. The high quality tungsten carbide pin could be cold coated in the work surface and on the up and down beveled shoulder.
We also could weld carbide particles in the surface according to customer requirements.
Stabilizer work with surface hardening and the hardening forms are HF1000, HF2000, HF3000, HF4000, HF5000 and HF6000.

Application
The drilling stabilizer Application
When the drill string is rotated at high speed in the hole, the slender drill pipe is kept running smoothly, so that the bit axis is as close as possible to the center line of the drill hole, also called the centralizer, which is used in oil, gas and
geological exploration drilling projects. An important tool for changing the inclination of the well. The stabilizing effect is mainly to reduce the radial and axial violent vibration of the drill string elastic system in the hole; to reduce the eccentric wear of the drill bit and the drill pipe; to ensure the core quality; to prevent the well inclination or to use manual directional drilling. The stabilizer has a relatively simple structure and is a large diameter joint with rib pieces (straight or spiral). The form of the stabilizer can be divided into a drill string type and a bottom hole type.
Also known as the centralizer, it is a tool for stabilizing the downhole drilling tool and acting as an anti-slope. A device that is attached to a section of the drill string near the large diameter drill to stabilize the direction of the drill.
