Some techniques to rationally lay out the pipeline networks and handle the gas pulsation are given. 提出了管网系统合理布局、脉动补救措施等方法。
This paper introduces the methods to lay the all-plastic cable in the pipeline, and the issues worth paying attention. 介绍了在管道中敷设全塑电缆的几种方法及注意事项。
The models lay a foundation of setting up the mathematic models for the pressure drop calculation in the crude oil pipeline with drag reducer, the wastage of drag reducer and the optimized design. 两个数学模型为加减阻剂原油管道的压降计算、减阻剂耗量计算、优化设计数学模型的建立打下了基础。
Lay the theoretical foundation for the identification of the defect leakage magnetic field and magnetic flux leakage produced by the pipeline components. Obtain the characteristic parameters of the leakage magnetic field by the finite element analysis of defects, fill plates, flanges, weld and branch pipe. 通过对缺陷、补板、法兰、焊缝、支管所产生漏磁场的有限元分析,得出缺陷与各管道部件漏磁场的特征参数。
This paper first simulate the pipe directly lay on the seabed model; and by changing the pipeline and the soil physical and mechanical parameters, analyse the characteristics of pipeline settlement. 首先模拟了管道直接铺设在海床上的模型,通过改变管道和土体物理力学参数,分析管道的沉降特性。
