This paper discussed the modality of ringed piping in the procedure of fire fighting
讨论了消防过程中环状管网中的水流状态。
We have been used to calculate the diameter of ringed piping according to ramiform piping , then it result in the bigger diameter and wasting of investment
长期以来，习惯环状管网管径按枝状管网计算，管径偏大，造成浪费。
It figured out that there was flow of water not only in the calculated pipeline but also in other pipelines and that diameters of hydrant ringed piping should be ensured after calculation
认为某一点着火后，不仅是计算管路有水流通过，其他管路也有水流经过，消火栓环状管网的管径应通过计算确定。
Analyzed the outcome of an engineering practice calculation , the diameters value calculated in theory of hydrant ringed piping is less than the value of manual . so it is recommended that the conclusion should be accepted by < < code for fire protection design of buildings > > and < < code for fire protection design of tall buildings > >
通过对工程实例的计算结果分析表明，在按理论计算时，环状消火栓给水系统管道管径小于规范最小管径要求，建议《建筑设计防火规范》和《高层民用建筑设计防火规范》采用。
