Buried depth of rain water pipe should be buried in the frozen line, consideration should be given to the upper part of the load pipeline.
埋地雨水管的埋没深度应在冰冻线以下,应考虑管线上部的荷载。
2
Then combined pipe-line theory, the accumulator's integrated mathematical model with incurvate and strange diameter series connection pipeline is built.
然后结合管道理论研究得出了带有弯曲管路、异径串联连接管路的蓄能器数学模型。
3
The leakage current must be returned to the source, it will flow through any available thermocouple conductor, linepipe, pipeline, water or earth went to the source.
