This results in individually manufactured pipe connections used as adapters for connecting to catalytic converters. The pipe connection can be manufactured simply in structure and can connect four or more individual pipes to the connection pipe of the exhaust gas catalytic converter. Here, the individual pipes extending into the pipe connection are compressed together to a fastening flange with a catalytic converter to form a pipe member of four triangular cross sections which are joined together, for example by welding. The pipe members are fastened by welding in the holes of the fastening flange.
파이프 연결체 내의 파이프 부재들은 배기 파이프의 개별 파이프들 상에 또는 그들 내에 끼워져서 억지 또는 헐거운 끼워 맞춤되어, 배기 파이프 내의 높은 온도에도 비틀림이 발생되지 않는다.The pipe members in the pipe connection are forcibly or loosely fitted to fit on or within the individual pipes of the exhaust pipe so that no distortion occurs even at high temperatures in the exhaust pipe.
파이프 연결체는 하우징 케이싱을 갖고, 파이프 부재들 사이에 개별 파이프에서 외측 파이프에 의해 연장되는 공기 챔버가 형성되어, 엔진 연결부로부터 촉매 컨버터까지 연속적인 공기 챔버와 연속적인 단열재가 제공된다.The pipe connection has a housing casing, and an air chamber is formed between the pipe members, which is extended by an outer pipe in a separate pipe, to provide a continuous air chamber and continuous insulation from the engine connection to the catalytic converter.
하우징 케이싱은 대체로 개별 파이프들의 외측 파이프가 끼워진 성형링을 통해 각 개별 파이프와 연결되고, 하우징 케이싱 및 외측 파이프와 용접 가능하다.The housing casing is generally connected to each individual pipe via a forming ring fitted with the outer pipe of the individual pipes and is weldable with the housing casing and the outer pipe.
공기 챔버는 성형링 영역에서, 개별 파이프들로부터 하우징 케이싱 내로 전환이 이루어진다.The air chamber is switched from the individual pipes into the housing casing in the forming ring region.
파이프 연결체는 파이프 부재들을 원형 단면의 파이프로 프레싱함으로써 하나 이상의 작동 통로로 형성된다. 하우징 케이싱은 용접에 의해 체결 플랜지 내에서 연결되고, Z형 성형링이 제작되어 개별 파이프의 외측 파이프에 연결되어서 열팽창이 가능하게 된다.The pipe connection is formed into one or more working passages by pressing the pipe members into a pipe of circular cross section. The housing casing is connected in the fastening flange by welding, and a Z-shaped forming ring is manufactured and connected to the outer pipe of the individual pipe to enable thermal expansion.
