| Summary: | Economic growth and the successive demand for consumption goods stimulate development of new industrial techniques and technologies. One of such advancements is HDD technology, thanks to which underground pipelines can be disposed in the ground without troublesome digging of the future investment site. When designing the borehole trajectory, attention should be paid to its technical and technological constrains. One of them is the strength of the drill pipes. The HDD process was characterized and relevant formulae for calculating minimum bending radius of drill pipes were presented in the paper. The influence of drill pipes wearing on the increase of minimum bending radius value was shown. |
