24-54 O ÎNCERCARE DE FORMARE DOP DE GHEAŢĂ PE UN TRONSON DE CONDUCTĂ ORIZONTALĂ ÎNTR-O BUCLĂ HIDRAULICĂ EXPERIMENTALĂ DE JOASĂ PRESIUNE


AN ATTEMPT TO FORM AN ICE PLUG ON HORIZONTAL
PIPE SECTION INTO LOW PRESSURE HYDRAULIC
EXPERIMENTAL LOOP
In the pipe-line installation, using fluids in liquid state at maximum
temperature of 30°C, the ice plugging technique assumes to form an ice plug
under controlled process inside of horizontal pipe line. The ice plug is
maintaining until completion of the maintenance / repair works made in circuit
without shut-down installation. Development of such applications by the
Institute for Nuclear Research assumes to perform design works, elaboration
and qualification of fabrication/ testing technology for some applications
considered as representatives and accumulation of experience required for
handling at detail level of ice plug primary forming and local extension for few
flow agent types used in domestic and industrial installations.
The paper describes a constructive and functional description of the
experimental technological facilities. The first results and some conclusions are
presented. The paper is dedicated to specialist working in the research and
technological engineering.
