To provide a thermal decomposition pipe that can improve heat transfer efficiency while exerting effect of stirring internal fluid of a pipe.SOLUTION: A thermal decomposition pipe 10 is formed with one or more fluid stirring elements 20 while projecting inward at an inner surface of the pipe. The stirring element includes: a helical first projection 21 extending along the inner surface of the pipe and projecting so as to turn right or turn left downstream relative to a pipe axis; and a helical second projection 25 extending along the inner surface of the pipe and projecting so as to turn in an opposite direction to the first projection downstream relative to the pipe axis.SELECTED DRAWING: Figure 1 【課題】本発明は、管内流体の撹拌効果を具備しつつ熱伝達効率の向上を図ることのできる熱分解管を提供する。【解決手段】本発明の熱分解管１０は、管の内面に１又は複数の流体の撹拌要素２０を内向きに突出形成してなる熱分解管であって、前記撹拌要素は、前記管の内面に沿って延び、管軸に対して下流向きに左旋回又は右旋回するように突設されたらせん状の第１突条２１と、前記管の内面に沿って延び、管軸に対して下流向きに前記第１突条とは逆向きに旋回するように突設されたらせん状の第２突条２５と、を含む。【選択図】図１
