Different from cold rolling which is performed below the recrystallization temperature, hot rolling is conducted above the temperature. Hot rolled seamless pipes offer higher torsional rigidity than cold rolled ones, thus it offers better torsional resistance than cold rolled tubes.
The hot rolled seamless steel pipe is typically applied to construct the pipeline system for low, medium and high pressure boilers.
