The Role of the Hardfacing of the Non-Magnetic Stabilizer
Petroleum non-magnetic stabilizer is an accessory used for oil field extraction, mainly used to reduce friction between drill pipe and hole wall, prevent drill pipe bending, and ensure that the drill bit drills at the designed angle and trajectory. Non-magnetic stabilizers are usually made of ...Read more -
Structural features of drill bit
1. Floating bearing structure is adopted, and the floating element is made of new materials with high strength, high elasticity, high temperature resistance and high wear resistance, and the surface is treated with solid lubricant. While reducing the relative linear velocity of the bearing pai...Read more -

Would you like to know more information about one type steel for bits? (part 1)
The 20CrNiMo series steel is a widely used Cr-Ni-Mo surface-hardening steel, primarily applied in carburizing and carbonitriding processes. With relatively low contents of chromium (Cr), nickel (Ni), and molybdenum (Mo), this steel exhibits excellent forgeability, machinability, and weldability. ...Read more -
Installation and Use of Stabilizer
1.Introduction to the stabilizer The stabilizer is a cementing tool that is easy to manufacture, has a beautiful structure, is sturdy and durable, and has a strong straightening force. It overcomes the shortcomings of the original welded stabilizer, which is prone to detachment, and is a stabiliz...Read more -
Surface treatment of forging
Many mechanical parts work under alternating loads and impact loads such as torsion and bending, and their surface layers are subjected to higher stress than the core; In the case of friction, the surface layer is constantly worn out. Therefore, the requirements for strengthening the surface laye...Read more -
A Steel Material For Drill Bits (Part 2)
3.3 High Magnification Examination Samples are taken from the R/2 position of the rolled steel bars. These samples are subjected to tests for non-metallic inclusions, austenite grain size, and banded structure. Furthermore, the microstructure of the samples is analyzed in detail under a microscop...Read more -
Raw Materials for Forging
1.Common types of raw materials 1) Carbon steel and alloy steel: Carbon steel: including various components of carbon steel, it is one of the most commonly used raw materials in forging. Alloy steel: a mixture of metal and one or more metal or non-metal elements, characterized by high strength, g...Read more -
