THE CONVENIECE OF VISUALISING THE CONTROLLED FORMATION OF ICE PLUGS IN HORIZONTAL PIPE-LINE SECTION
The technique of forming controlled ice plugs in pipe-line installations in order to isolate a section from the rest of the circuit is used for carrying out circuit maintenance or repair activities without shutting down the entire installation. The geometrical characteristics of the ice plug can vary from one test to another, depending on the conditions under which the test is being carried out and the events that occur during this time. Studying this process requires visualizing the forming of ice layers inside the pipe.
This paper describes the convenience of visualizing the formation of ice plugs by studying the effect of the events and interventions that occur during controlled tests that have been carried out in horizontal pipe-line sections.
Key words: isolating a pipe-line section, visualizing the forming of ice layers
