过去我们在室外管道敷设的设计中,对各种管子都规定了坡度的要求,这种要求有时是有利的,但是有时却也带来了不少不利因素,而且在室外管道设计中,一般来说,不利的因素大于有利因素。所以为了提高工程的设计质量。我们在60年代末开始,对室外管道中的部分管道,进行了无坡度敷设设计的试点,并取得成功,因此1974年我们在金山石化一厂的厂区管道设计中,全面推广了这种敷设方法,该厂除火炬管道外,均采用
In the past, in the design of outdoor pipe laying, slope requirements were specified for various pipes. This requirement was sometimes favorable, but sometimes it also brought a lot of disadvantages, and in the design of outdoor pipes, generally Said that the adverse factors are greater than the favorable factors. So in order to improve the design quality of the project. At the end of the 1960s, we began piloting the design of slope-free laying for some of the pipelines in the outdoor pipelines and succeeded. Therefore, in 1974, we fully promoted this laying method in the pipeline design of the Jinshan Petrochemical Plant. In addition to the torch pipeline, the plant uses
