For the air cooler inlet pipe,the discussion was carried out at the view point of bias control,the adjustment of pipe flexibility,and the nozzle press requirement.The inlet pipe should be arranged symmetrically to the largest extend to avoid bias.To reduce the nozzle stress of the air cooler,the small branch at the inlet should be firstly adjusted to maintain sufficient flexibility as the basis to ensure the entire system to have enough strength,rigidity and stability.The pipe stress design should consider the start-up conditions and the displacement of air cooler nozzle.
