中压蒸汽管道吹扫所用的规范？ 企标，仅供参考。 4.5.6 each system shall be blown with the type of steam (e.g., low-, medium- high-pressure steam) it will carry during normal operations. the volume of steam during blowing shall be at least three (3) times the maximum operating volumetric flow rate, except as provided in section 4.5.11.5 below. 每个系统应根据蒸汽类型（例如低压蒸汽、中压蒸汽、高压蒸汽）用其操作压力进行吹扫。除了下列4.5.11.5的规定，吹扫期间的蒸汽量至少是最大操作流量测定体积的3倍。 the required steam flow during the blowing cycle shall be determined by calculating the disturbance factor (df), where 在吹扫过程中需要的蒸汽流量应通过计算干扰因数决定。 df = (rb)2 * dc / [(ro)2 * do] rb = flow rate during blowing吹扫时流速 ro = flow rate during operation操作时流速 dc = density of blowing medium吹扫介质密度 do = density of operating medium操作介质密度 a disturbance factor of 1.3 to 1.5 will give the required flow rate during the blowing cycle. 在吹扫期间给出的流速要使干扰因数在1.3 至1.5之间。查看更多
