城市燃气管道铺设一般都是在地下进行,主要的供气设备有输送燃气的管道、燃气高压站、燃气调压装置及其附属设备共同组构而成。通常情况下城市燃气管道的铺设选用直埋方法。管道老化等其他突发性因素会造成燃气泄露,同时大量空气可能会涌入燃气管道内,从而产生压强,进一步造成燃气管道的爆炸现象,更严重的情况则是由于管道泄露燃气遇到高温的状况时。极有可能引发重大火灾隐患。全球每年由于管道燃气泄露造成的各种灾害事故也屡有发生。因此城市燃气管道的安全铺设工作己在城市基本建设中占据了重要的地位。
City gas pipeline laying are generally carried out underground, the main gas supply pipeline gas transmission equipment, gas pressure station, gas pressure regulating device and its ancillary equipment together formed. Under normal circumstances, the laying of urban gas pipeline using direct burial method. Gas leaks can be caused by other unexpected factors such as pipeline aging and large amounts of air may flow into the gas pipe to create pressure that further causes the gas pipeline to explode. More often, the gas leaks through the pipe to expose the gas to high temperatures When the situation. It is very likely to cause a major fire hazard. Every year, various disasters and accidents caused by pipeline gas leakage occur frequently in the world. Therefore, the safe laying of urban gas pipelines has occupied an important position in urban infrastructure.
