HEAT TRANSFER TUBE FOR DEFECT REPAIR METHOD OF HEAT EXCHANGER

摘要

PURPOSE: An electric heating tube defect repairing method of a heat exchanger is provided to repair an electric heating tube using an adhesive material, thereby preventing damage of a spiral sleeve due to thermal deformation. CONSTITUTION: An adhesive material is coated on a spiral sleeve which is used for repairing an electric heating tube defect of a heat exchanger(S10). The spiral sleeve in which the adhesive material is coated is carried to a defect site of an electric heating tube(S20). The carried spiral sleeve is attached to the defect site of the electric heating tube(S30). The spiral sleeve which is attached to the defect site is solidified(S40).
