First of all, through the treatment of the steel pipe thickening process, the surface of the light pipe is bent inward, and the wall of the steel pipe is thickened. The next step is to process the thread and plate it with copper that can enhance strength. Then carry out a non-destructive quality control inspection, and then carry out the welding of the steel pipe joint. Then, the pipe body is welded with heat treatment and welding to eliminate the residual pressure of welding. Before painting and packaging the finished drill bit, carry out other testing of the finished steel pipe G105 oil drill bit 4140H drill bit, including hardness detection, pressure detection and non-destructive testing. The length of the drill pipe is generally about 9 meters.

In addition to connecting, the oil drill pipe thread mainly transmits torque. However, frequent twisting and unloading is an important reason for the wear of drill pipe threads. In order to extend the life of the drill bit screw, in addition to improving the material, processing accuracy and heat treatment technology of the drill bit joint, a reasonable screw tolerance value and tolerance range are also needed.

Oil drill pipes are mainly suitable for the construction of deep wells, horizontal wells and large displacement wells in the process of oil and gas exploration and development. The drill bit is a steel pipe with a cutting line at the tail, which is used to connect the drill bit equipment and bottom hole device at the bottom of the drill bit. The purpose of the drill pipe is to transport the drill bit mud to the drill bit, and raise, lower and rotate the bottom hole device with the drill bit. The drill pipe must be able to withstand huge internal and external pressure, distortion, bending and vibration. In the process of oil and gas extraction and lifting, the drill pipe can be used many times. The light pipe and the original steel pipe have been processed many times to make drill bits.
