水电站引水压力钢管安装质量是一座电站安全运行的重要条件,但是,压力钢管安装的质量受多方面因素的制约,施工质量不易控制。在我国,有水电站压力钢管失稳导致钢管道报废的,有压力钢管爆裂导致安全事故发生的。在龙滩水电站,压力钢管施工完成后,进行流道检查时发现2#机压力钢管道钢管内壁上有两处鼓包。专家建议由有经验的专业人员进行焊接处理。
The installation quality of hydropower station water diversion pressure pipe is an important condition for the safe operation of power station. However, the quality of the pressure pipe installation is restricted by many factors and the construction quality is not easy to control. In our country, there are hydropower station pressure pipe instability lead to scrapped steel pipe, a burst of pressure pipe led to a safety accident. In Longtan Hydropower Station, the construction of the pressure pipe is completed, the runway inspection found 2 # pressure steel pipe wall with two drums. Experts recommend welding by experienced professionals.
