What is the best way to handle bend or turns in slurry piping systems?

What is the best way to handle bend or turns in slurry piping systems?
by

1 Answer

Answer :

Even long radius elbows should be avoided in slurry pipes and lines. They are often the site of severe  erosion or solid/liquid separation. Only gentle pipe bends or sweeps should be used to turn a slurry line.  Industrial experience has shown that a bend-radius-to-pipe-diameter ratio of 3-5 is recommended.
