The main purpose of warming the pipes before starting the turbine is to eliminate temperature differential stresses within the pipes and equipment, thereby preventing uneven thermal expansion due to rapid heating, which could cause deformation, damage, or leakage in the pipes, valves, and turbine components. Furthermore, the warm pipes can also remove the condensate water inside the pipes, preventing water hammer during the startup of the turbine and thus ensuring the safe and stable operation of the equipment. .
