Abstract

PURPOSE: To allow the adoption of an engineering method, which interrupts the fluid of liquid in a duct by compulsorily freezing liquid in the duct at fixed points before and after exchange prearranged piping for an extremely short time, even when static press. except transportation press. is applied to liquid in the duct.
