摘要
城市燃气是城市建设的重要基础设施之一,也是城市能源供应当一个重要组成部分,它为城市工业、商业和居民生活提供优质气体燃料。城市燃气输配系统的绝大部分系统的绝大部分工程量,属与城市地下基础工程。
本设计主要是针对该市区进行天然气供气的规划。该设计使用的天然气管道主要是钢管。该市区总供气面积为875公顷,人口达35万,属于中小型市区,单人口密度400人/每公顷,规划时要考虑该市的发展。进行规划时除建设接收长输管线天然气的储配站外,还需考虑设置区域调压站,G加气站。因此,除管网的水利计算外,还要有储配站,区域调压站的设备选型计算。因此本设计囊括了从长输管线到储配站,经过区域调压站最后进入区域管网的过程。

Abstract
Natural gas is one of urban construction's important basis facilities, is also the urban energy for must a ponent, it for the urban industry, the trade and the resident lives provides the high quality gaseous fuel. Natural gas loses matches system's major part system's major part resilience, is with the city underground foundation engineering. This design is mainly aims at Jia city to carry on the natural gas air feed the plan. The design is PE pipe used in gas pipelines. The city total air feed area is 875,000 square kilometers, the population reaches 35,0,000, belongs to the large and middle scale cities, the single population density is low, when plan must consider this city the development. Carries on when the plan receives gas distribution who besides the construction long loses the pipeline natural gas to stand, but must consider that establishes the region accent to press the station. Therefore, besides work's water putation, but must have Gas distribution stations, the region accent presses the station the equipment putation. Therefore this design included has lost the pipeline from a long-range point of view to Gas distribution stations, adj
