This work deals with finding the solution of reparing of cereal transporting pipeline. According to existing literature this problem has not been adequately treated, thus the above mentioned tribological problem has not been sufficiently explored. The specimen materials were selected according to availability of materials, practicability and acceptability of cost. Obtained research shows that the most critical parts of the pipeline cen be manufactured from non-alloyed steels, which includes improved surface resistance by hard facing. |
