Geological Drilling Pipe


Geological tube
is steel pipe that using core drilling for the geological department, which a hollow cross section, surrounded by long geological drilling joints with steel pipes.

Geological pipe (YB235-70) with a hollow cross section, a large number of pipes, for conveying fluids such as the transportation of oil, gas, gas, water and some solid materials, pipes, etc. By end-use can be divided into the drill pipe, drill collars, the core pipe, casing and precipitation tubes.

To explore the underground rock structures in the practical application of geological tubes, geological drilling pipe, groundwater, oil, gas and mineral resources, the use of rigs drilling wells. Oil, gas, mining can not be separated from the drilling wells, geological drilling and oil drilling seamless steel pipe, drilling equipment, including the core outer tube, core tube, casing, drill pipe. Drilling tube deep into the depth of several kilometers strata, the working conditions are extremely complex, the drill pipe to withstand tension and compression, bending, torsion, and the uneven impact load stress, but also by the mud, rock wear, therefore, the requirements of the pipe must have sufficient strength, hardness, wear resistance and impact toughness.
