日本全国各城市的煤气公司在向居民供气的终端低压管道上,使用能承受曲伸压力的具有抗震性能的聚乙烯管(简称 PE 等)的普及率进一步提高。为了在遇到和1995年1月发生的阪神大震灾同样规模的地震时,将震害减小 Gas companies in cities throughout Japan have further increased the penetration rate of polyethylene pipes (abbreviated as PE) that can withstand bending and stretching pressure on the low-pressure pipelines that supply air to residents. In order to encounter earthquakes of the same magnitude as the Great Hanshin Earthquake in January 1995, the damage will be reduced.
