However, steam inevitably produces condensate water in the conveying process due to reasons such as pipe heat dissipation. If the condensate water cannot be discharged from the steam pipe network in time and effectively, a series of problems will be caused. On the one hand, the accumulation of condensate water may cause water hammer phenomenon in the pipe. When steam pushes the condensate water to flow at high speed in the pipe, strong impact will be generated when the condensate water encounters pipe bends, valves and other parts.
