Underground Crawler Hydraulic Drilling Rig Special Geological Round Drill Pipe

 Geological drill pipe is one of the important tools in the production process of geological exploration and coal mine exploration. The geological drill pipe adopts high-quality, efficient, energy-saving and pollution-free friction welding technology, and conducts research on the post-welding heat treatment process, and obtains a toughened geological drill pipe, and the comprehensive mechanical properties of the welded joint are higher than the values specified in the DZ60 geological drill pipe technical standard.
  The role of geological drill pipe:
Drill pipe is used to connect the surface equipment of the drilling rig to the drilling equipment or the bottom hole device located at the bottom end of the drilling, and is a steel pipe with a reeling at the tail. The purpose of the drill pipe is to transport the drill mud to the drill bit and to raise, lower or rotate the drill bit through the bottom hole device. Drill pipes must be able to withstand enormous internal and external pressures, twisting plums, bending forces and vibrations. Drill pipe can be reused during mining and refining.
  Raw steel pipes and fluorescent tubes are made into drill pipes after multiple processing steps. First of all, through the treatment of the steel pipe thickening process, the surface of the light pipe is bent inward, and the steel pipe wall is thickened. Next, threading is done and plated with copper that increases strength. This is followed by non-destructive quality control, followed by welding of steel pipe fittings. The tubing then undergoes weld heat treatment and welding final treatment to eliminate residual welding pressure. Before painting and packaging the finished drill pipe, a number of other tests are carried out on the finished steel pipe, including hardness test, pressure test and non-destructive test.
