The present invention relates to a stainless flue exhaust pipe with a semi-permanent life and a manufacturing method thereof, which can form a ceramic coating layer inside the stainless flue exhaust pipe by using diatomite and ceramic fiber powder. The exhaust pipe manufactured by the manufacturing method of the present invention does not cause corrosion by an acid, such as sulfuric acid, sulfurous acid, hydrochloric acid and the like, which is produced by dew condensation water or rainwater. Moreover, the exhaust pipe can be semi-permanently used without a removal or a cracking phenomenon even at high temperature. 본 발명은 반영구적 수명을 갖는 스텐레스 연도 배기관 및 그 제조 방법에 관한 것으로, 구체적으로 스텐레스 연도 배기관의 내부에 규조토 및 세라믹 섬유 분말을 이용하여 세라믹 도막층을 형성하는 것을 특징으로 한다. 본 발명의 제조방법에 의해 제조된 배기관은 결로수나 빗물에 의해 생성되는 황산, 아황산 및 염산 등의 산에 의한 부식이 발생하지 않고, 고온에서도 탈각되거나 균열이 일어나지 않아 반 영구적으로 사용 가능한 것을 특징으로 한다.
