| Abstract: | Based on the gravity transport technology of two-phase flow in pipelines and by combining with field cases, the accidents in pipeline transport of filling slurry is analyzed hydraulically. It is pointed out that water impact is the key reason of pipe cracking, slurry ejection, etc. For this reason, some safe and economic transport measures are put forward and the formula for calculating rational pipe diameter and length is derived. The field test results show that the scheme is feasible and effective. |
