Maintenance management of geological drill pipe after use
As an important part of the whole drill string, drill pipe is widely used in hydrological surveying, geological drilling, oil and gas exploration and other fields. The quality of drilling tools, the quality of on-site maintenance and utilization, drilling accidents, and construction costs have a significant impact. The following editors of Huanye Machinery only discuss the use of friction welding bits and the maintenance management of construction sites, and discuss their surface knowledge.

What is the difference between solid (one-piece) drill pipe and friction welded drill pipe?
The friction welding drill pipe is made of two drill pipes connected together by friction welding technology (under the action of pressure, the temperature of the friction interface of the workpiece to be welded and its vicinity increases, so that the material is plastically deformed, accompanied by the material It is a solid-state welding method that produces plastic rheology and realizes welding through molecular diffusion and recrystallization at the interface.) The weld can reach the strength of the forged structure, which can theoretically be comparable to the base metal.

Crawler type full hydraulic cave drilling rig for coal mine
1. Using hydraulic mechanical control, using static pressure water, the cave can be completed without a high-pressure pump station; 2. It can be used for different geological conditions such as rock formations with f < 6, and has a wide range of applications, which can meet the needs of rock roadway burrowing and pressure relief and coal seam burrowing construction;

With the continuous strengthening of sand fracturing and acid fracturing technology and the continuous increase of the depth of oil and gas wells in China, the fracturing pump is increasingly developing in the direction of large displacement, high pressure and high power. With the development of oil and gas exploration technology, the distribution of oil and gas wells is becoming more and more extensive, and the requirements for the mobility of fracturing equipment will be higher. Therefore, the working conditions of the fracturing pump are worse, and it is of great significance to further improve the service life of the fracturing pump and to carry out structural improvement and overall research on it.

How to carry out daily maintenance of diamond drill bits
Diamond drill bits are suitable for coal mining, geological exploration work and various engineering drilling, but the problem of various technicians is how to carry out daily maintenance. For diamond compact drill bits, today we should explain how to carry out diamond drill bits according to the requirements of diamond drill bit users. routine maintenance.

It is produced at high temperature during welding, so it is called hot crack, which is characterized by cracking along the prior austenite grain boundaries. Depending on the material of the metal to be welded (low-alloy high-strength steel, stainless steel, cast iron, aluminum alloy and some special metals, etc.), the shape, temperature range and main reasons for hot cracking are also different. At present, thermal cracks are divided into three categories: crystalline cracks, liquefaction cracks and multilateral cracks.
