ATTEMPTS TO FORM ICE PLUG ON DRINKING/POTABLE WATER FLOWING THROUGH HORIZONTAL PIPE SECTION (of 200 mm nominal diameter)
In the hydraulic pipe-line installation, the cutting-off flow technique on a line (horizontal pipe) assumes to form an ice plug under controlled process or two ice plugs, for its isolation. On both cases the ice plug (or both ice plugs) is maintaining until completion of the maintenance / repair works made in circuit without shut-down installation. The paper describes a constructive and functional description of the experimental technological facilities followed by few sequences chosen from two tests carried out for potable water, and finally, the results and conclusions get. The paper is dedicated to specialist working in the research and technological engineering.
