Abstract

PURPOSE: To prevent generation of the lap defect like as the crack, the turnup, etc., by heating the pressure liquid to maintain the temperature of the expanded part of the pipe at suitable temperatures, in case of applying the hydraulic pipe expanding work to the pipe of low toughness.
CONSTITUTION: In case of expanding the pipe 2 inserted into the tube plate 1, if the pipe 2 is made of an alloy possessing a low toughness at the normal temperature like as the ferrite stainless steel, the pressure liquid is heated by the heater 6 to about 80W100°C under control of the temperature controller 7; then the pressure of the pressure liquid is raised to high by the high pressure pump 8, and is fed to the hydraulic pipe expander inserted into the pipe so as to locate at the expanded position; hereby, the hydraulic pipe expanding work is performed.
