1. A heater system for a pipe, comprising:
a heater body part including a plurality of heater body split parts on which a longitudinal cutting plane and a circumferential cutting plane are formed, and each of the heater body split parts having a heating line installed therein;
a power source connected in parallel to the heating lines;
a confinement and manipulation part configured to confine the heater body part in a cylindrical form;
a plurality of temperature sensors installed in the heater body split parts, respectively, and configured to measure temperature values of the heater body split parts, and generate measured temperature information based on the measured temperature values; and
a control module configured to control the power source depending on the measured temperature value from each of the temperature sensors,
wherein the control module includes:
a memory configured to store reference temperature information and first failure current compensation information which corresponds to a value of current that compensates for lowered temperature values of a first one of the heater body split parts due to a heating failure thereof; and
a controller configured to compare the reference temperature information stored in the memory with the measured temperature information, and to control the power source to adjust an internal temperature of the heater body part based on the first failure current compensation information when the measured temperature information is lower than the reference temperature information.
