摘要
The present invention relates to a solution processing apparatus for a gas pipe internal pipe using a high frequency wave, the apparatus comprising: an insulation pipe (120); An inner tube (101) of a gas pipe which is located inside the insulating tube (120) and generates heat at a high temperature when a high frequency current is applied to the induction coil (112); And a high frequency current supply unit 111 for supplying a high frequency current to the induction coil 112 and the induction coil 112 wound around the insulator 120 and flowing a high frequency current. A high frequency heating device 110 for heating and solution treatment; A plurality of first injection holes 131 formed in the insulating layer 120; A first gas supply means (141) for injecting a first inert gas through the first injection hole (131); An adapter 150 for shielding the outside oxygen from being directly contacted with the gas piping inner pipe 101 heated to a high temperature and radiating heat to the inner pipe 101 of the gas piping inside; A plurality of second injection holes 132 formed in the adapter 150; The second inert gas may be introduced into the second injection hole 132 so as to prevent the inner tube 101 of the high-temperature gas pipe, which has been subjected to the solution treatment, And a second gas supply means (142) for injecting the gas through the second gas supply means. According to this, there is an advantage that the solution treatment of the inner pipe of the gas pipe can be performed at a low cost.
