Slurry piping system, like any other system, consists of slurry pumps, pipelines and valves. Special considerations relevant to this systems are introduced by the fact that slurry in not homogeneous phase (unlike gas or liquid). Slurry can be described as liquid with solids suspended therein. Typical industrial instances of slurry handling are:
