초록

도시가스 배관의 손상부에 대한 적절한 보수방법은 안전한 가스이송 및 가스 배관의 파손으로 인한 경제적 손실을 줄일 수 있는 중요한 요소이다. 육성용접, type-A 슬리브, type-B 슬리브 그리고 복합재료 슬리브와 같은 보수 방법들이 현재 도시가스 배관 보수에 사용되고 있다. 본 연구에서는 여러 보수방법중 비교적 손쉬운 보수절차로 인해 작업자의 숙련도에 의존하지 않으며 쉽고 경제적으로 보수 할 수 있는 복합재료 슬리브를 이용한 보수방법에 관한 연구를 수행하였다. 특히 탄소섬유 프리프레그를 사용한 복합재 보수방법과 그 결과에 대해 논의하였다.

Proper repair methods of damaged city gas pipeline is important factor to safely transmit gas and to reduce economical loss caused by failure of gas pipelines. Repair methods such as surfacing, type-A and type-B welding and composite sleeve method have been used to repair damaged city gas pipelines. In this paper, among repair methods, composite sleeve repair methods were conducted since they are rather simple processes and their repair quality is not sensitive to workers' ability compared with other repair methods. We discussed composite repair processes especially using carbon fiber prepregs and the experimental results.
