Flushing of the pipes and tubes

To do pipe flushing correctly we need to provide the special conditions to create turbulent flow. This is required to remove particles from the surface inside spindle tubes. For that we need:

  1.  High velocity of the flushing fluid (not be less than 2 to 3 m/sec. = 106 ft./sec.)
  2.  High temperature of the flushing fluid (a minimum temperature should be 140°F = 60°C)
  3.  Low viscosity of the flushing fluid (in the 10 to 15 cSt range at 104°F = 40°C)
  4.  The pressure of the flushing fluid should be held to a minimum 3 to 5 bar (22 to 73 psi), measured downstream from the flushing circuit, before the return line filter and sampling port
  5.  The flushing time to be 30 min.

Next good references about flushing I found in the internet and want to share:
