A CONTROLLED ICE PLUG FORMING EXPERIMENT
CONDUCTED ON A HORIZONTAL PIPE SECTION (NPS 12)
WITH DEMINERALIZED WATER FLOWING THROUGH
In a hydraulic pipe-line installation, isolating a horizontal section
requires forming one or two ice plugs in a controlled process. This technique is
used for carrying out circuit maintenance or component replacements without
shutting down the entire installation. In both cases, the ice plug (or both ice
plugs) must be maintained until completing the repair activities. This paper
describes an experiment conducted on a horizontal NPS 12 horizontal pipe
section and its sequences, followed by the results and conclusions. The paper
is dedicated to specialists working in research and technological engineering.
