SLJ DLJ201-80规范是70年代未修订,改革开放以来,我国高水头和大容量的大型水电站不断兴建,压力钢管用材也随着由普低钢进入高强钢。SLJ DSJ201-80规范已不能满足需要,故能源部决定将SLJ DLJ1201-80规范列为1991-1993年修编项目,考虑该规范内容多,篇幅大,为便于实施,将该规范分为下列三项规范分别修编: 1.水利水电工程压力钢管制造安装及验收规范 2.水利水电工程闸门、拦污栅制造安装及验收规范
SLJ DLJ201-80 norms is not revised in the 1970s, since the reform and opening up, China’s high water head and large capacity of the continued construction of large hydropower stations, pipe material with the pressure from low to high strength steel. SLJ DSJ201-80 norms have been unable to meet the needs, so the Department of Energy decided to SLJ DLJ1201-80 norms 1991-1993 years as a revision project, considering the contents of the code, length, in order to facilitate the implementation of the specification is divided into the following three Item Specifications were revised: 1. Water conservancy and hydropower project pressure pipe manufacturing installation and acceptance of norms 2. Water conservancy and hydropower project gate, trash rack manufacturing installation and acceptance criteria
