Reducing mills in piece-reduction at the moment of capturing the pipe’s front end and on the rear end exit are exposed to increased dynamic loads. However these processes at present time are not fully researched. The relevant problem is to decrease dynamic loads in the clamp engine, to increase reliability and durability of the clamp on the basis of the mill’s production growth on the account of pauses decrease, rise of the production amount, and reducing in pipe costs. In the article the results of the study to define a part lifetime in the reducing mill stand have been presented. A part lifetime was calculated in month for more convenient comparison with the production data. The results have been hand over to JSC “PNTZ” for implantation.
