摘　　要：本文通过详细的水力计算,确定了天然气集中表箱表后采用的铝塑复合管的管径。分析了《城镇燃气设计规范》确定低压燃气管道总压力降的基本依据,并给出了两种切实可行的降低压差的方法。Through a careful hydraulic calculation, this article confirmed the diameter of the polyethylene-aluminum-polyethylene composite pipes which are fixed after the natural gas meter set in a concentrated gas meter box. After analyzing the basic foundation basing on which the Code for Design of City Gas Engineering＇ confirmed the terminal pressure decline on the low pressure gas pipeline, the author proposed two feasible method to reduce the pressure decline.
