When a turbulent body such as a vortex flows through the wall, for example, when the inner pipe is damaged due to a vehicle collision or the like and harmful substances flow out into the outer pipe, the harmful substances are turbulent in the outer pipe. It instantaneously mixes and reacts with the detoxifying substance contained in the fluid flowing in the fluid to be detoxified. Also, for example, in a heat exchange cylinder or the like, a fluid or the like that flows in a turbulent state between the inner pipe and the outer pipe causes the flowing fluid to flow through a turbulent flow such as a vortex by a flow partition wall having turbulent flow generation holes. By flowing in the shape, the heat exchange rate between the fluid and the inner pipe and between the fluid and the partition wall is improved, which has the effect of improving the heat exchange rate.
