RAPID FREEZING APPARATUS FOR A PIPE CAPABLE OF REDUCING FREEZING TIME

摘要

PURPOSE: A rapid freezing apparatus for a pipe is provided to be used regardless of the diameter of a pipe by covering the pipe using an outer jacket.;CONSTITUTION: A rapid freezing apparatus for a pipe comprises an outer jacket(110), a refrigerant supplying guide unit(120), and an outline fixing unit. One and the other ends of the outer jacket touch each other to cover the exterior shape of a pipe. The outer jacket is composed of a flexible material. When refrigerants are injected into the refrigerant space between the outer jacket and the pipe, the outer jacket is swollen to increase the volume of the refrigerant space. The refrigerant supplying guide unit supplies refrigerants to the refrigerant space. The outline fixing unit fixes both ends of the outer jacket. When the refrigerant space has a larger volume than a predetermined volume, the refrigerants leak from the refrigerant space to the outside.;COPYRIGHT KIPO 2013
