JSC Pervouralsk Pipe Plant is a subsidiary within the ChelPipe Group and specialises in the production of stainless steel tubes for a wide variety of industrial uses.
LOI Thermprocess roller hearth furnaces for the heat treatment of pipe material are ideal for the continuous production of larger throughputs. This extremely flexible furnace type is characterised by uniform heating, a definable holding time and subsequent material-specific cooling. The high temperature uniformity and the low energy consumption of these systems ensure reproducible processes, which can be precisely adapted to the desired heat treatment of the material. The drive sections can be optimally matched to the respective annealing process.
The heat treatment system for the JSC Pervouralsk Pipe Plant is designed as a roller hearth furnace for the bright annealing of 2,000 kg/h of austenitic stainless steel and nickel-based alloy pipes. The solution annealing of these high-alloy steel grades is carried out in the temperature range of max. 1,100 to 1,200 °C. The tubes are heat-treated in this continuously operating roller hearth system using a 100 % hydrogen atmosphere as process gas.
In addition to the equipment, the scope of delivery also includes installation and monitoring of commissioning by specialists from LOI Thermprocess.
