Dear:

 

Please share with me your idea about water washing of caustic line after construction.

 

Best regards

If you are referring to line flushing prior to commissioning, achieving water velocities between 1.5 and 2.0 m/sec will generally remove all dust and debris from the line. Caustic lines are normally of small diameter (<2") so you may achieve the same by purging the lines with steam or Nitrogen.

It is standard practice to wash new pipe and fittings with a safe fluid (water) after construction.  It is usually synergistic with pressure testing too.
