The article deals with the issues of modernization of the pipe rolling unit (TPA) with the Assel mill, in the conditions of changing its operational characteristics. A change in the performance characteristics of pipe-rolling equipment can occur when the brand assortment of pipes changes, as well as when the diameter of the finished pipes increases. In this regard, a methodology for calculating the energy-force parameters of the pipe rolling process at the Assel mill is given. An example of a practical solution to the problem of increasing the strength of the equipment, taking into account the conditions of action of both thermal and mechanical loads, is given. An example of a practical solution to the problem of increasing the strength of the equipment, taking into account the conditions of action of both thermal and mechanical loads, increased by 50 % relative to the active ones.
