A) transport properties of Assessment: solid proportion experiment grain size distribution of the slurry rheology experiments and experiments to determine the critical velocity, sedimentation velocity, pipeline resistance, pump pressure, straight pipe diameter
and wall thickness.
2) stop and then start the feature assessment: sedimentation experiments, experiments and mud bed rest slope penetration test is used to determine the maximum allowable pipeline laying slope and run mode.
3) assessment of abrasive slurries: erosion rate of the experiment, the slurry is used to determine the thickness of the wall of corrosion and abrasion margin.
