关于降低民用户燃气工程造价的探讨

Discussion of reducing the engineering cost of domestic gas user

对三个案例进行了造价分析及两种设计方案的比较,提出了通过降低民用建筑用户入口燃气压力,提高户内管允许压损,减小户内管管径,以及将原设计的一开一备一旁通的调压柜配置方案,改为一开一旁通配置方案,达到降低民用燃气工程造价的目的。

Through the analyzing and comparing of three cost-analyzing cases and two design plans,giving some suggestions to get the lower engineering cost of domestic gas user such as: 1)reducing the inlet gas pressure;raise the permitted total pressure lost in domestic gas pipes;reducing the diameter of domestic gas pipes.2)replacing the original regulator box piping system including one using one standby one by-pass piping system with one using one by-pass piping system.
