Geological drill pipe The geological drill pipe for coal mine is a geological exploration tool made of geological alloy steel pipe through friction welding process. The main body of the geological drill pipe adopts geological special alloy steel pipe (42MnMo7), and the drill bit of the geological drill pipe adopts high-quality alloy structural steel (42CrMo) through vacuum thermal conditioning treatment, which greatly improves the fatigue strength and shear strength. The production process of 1. products adopts imported friction machine welding. Moreover, the production process is very selective. The drill pipe has the characteristics of high bending strength, firm welding and no falling off. Can ensure the requirements for straightness when drilling deep holes, coal mine geological drill pipe has a high

1. product production process
The imported friction machine is used for welding, and the production process is very selective. The drill pipe has the characteristics of high bending strength, firm welding and no falling off. It can ensure the requirements of straightness in deep hole drilling, and the geological drill pipe used in coal mine has high fatigue strength and long service life.

3. product considerations
Due to the great pressure in the environment below, the drill pipe needs to be able to resist pressure first, otherwise it will be easily damaged underground. At the same time, because the head of the drill pipe in the water well will be equipped with a drill bit, under the action of drilling equipment, the drill bit will take the drill pipe to quickly go deep into the underground operation, which requires the drill pipe to have certain resistance to vibration.
Because the geological drill pipe is in the process of going deep into the ground, the situation of various strata is different, and the drill pipe will also be with these soils. Under the condition of meeting the basic purpose of mining geological drill pipe, the product can be used normally. If the installation and use are affected by site problems, please find a professional manufacturer to design and adjust separately according to the site implementation.
