Abstract
A temperature handling subsystem (12) for a pipe electrochemical polishing system (10) has a chiller (46) and associated heat exchanger (44) for cooling the acid electrolyte (24) circulating through a pipe (28) while a cathode (14) is drawn therethrough for the purpose of electropolishing the interior of the pipe (24). A temperature control method (48) has a temperature low enough decision operation (58) wherein a temperature indicating control (38) is used to determine if the chiller (46) should be activated. The electrolyte (24) is pumped by an electrolyte pump from an electrolyte reservoir (22) containing a temperature indicating controller (38) for determining the temperature of the electrolyte (24) and further containing an electric heater (36) for heating the electrolyte (24), as necessary.
