Pipe Wear In Industry
Some academics dedicate their life to studying advanced wear relations, but if you are looking for a simple, robust approach that is applicable in the mineral resources industry, try the method presented below.
It relies on a “pipe wear rate” which, for solids transport, has been adopted as 1.17 µm of wear for each 1000 t of solids transported.
|Suspended solids content||1,850||mg/l|
|Solids flow rate||kg/s|
|Wear rate||1.17||µm/1000 t|
Calculate the solids content of slurry by weight
Calculate the slurry density (specific gravity)
That is, the density of slurry is
Calculate solids content of slurry by weight
Calculate solids flow rate
Calculate total solids quantity
Calculate total wear
That is, the total wear over the course of the design life is 0.137 mm.
Once you have calculated the total wear, don’t forget to check whether the worn pipe wall thickness will sustain the total dynamic head acting on the pipe.
If you have a wear problem, or you would like to predict the expected wear for a new system you are installing, engage Pump & Flow to perform wear rate testwork. This test work will bring confidence that the piping system will satisfy the design life, without over committing capital.
