Abstract

복합파이프(1,1′)를 함께 용접하기 위서는 용접링(13)이 사용되며 용접링(13)은 환상의 링(4)의 측벽부분(7,8)을 누르게 된다.용접링(13)은 열가소성 재료로 이루어지며 전기저항가열(19)이 준비된다.
용접전 파이프(1,1′)의 전벽(10,10′)사이에는 환상의 틈(23)이 있으며 이 환상의 틈(23)에 체적 보상홈(24)가 용접링(13)에 연합된다.
내부 파이프(2)의 바깥쪽 구역에서 파이프(1,1′)의 결합은 서로 눌러주는 전벽(10,10′)는 용접되지 않는 방식으로 용접링(13)의 적어도 부분용접에 의해 이루어진다.
