Traditional exhaust pipes are usually made of single-layer iron sheets or red bricks. Exhaust pipes made of single-layer iron sheets have severe heat dissipation and high surface temperature, which are prone to scalding accidents. In order to avoid scalding, some exhaust pipes are made into double-layer structures, which can effectively reduce the surface temperature of the pipes and avoid scalding. However, the existing exhaust pipe outer shell and the inner smoke pipe are usually connected by welding. Therefore, it is necessary to add insulation material between the outer shell and the inner smoke pipe to prevent the outer shell from heating; and the welding process is cumbersome, the material consumption is high, and the production cost is high.
