Embodiment
For the ease of the understanding of those skilled in the art, further is made to the utility model with reference to embodiment and accompanying drawing
Explanation, the content that embodiment is referred to not to it is of the present utility model limit.
Embodiment 1.
As shown in figure 1, a kind of exhaust pipe structure that the utility model is provided, it includes straight tube 1, pipe fitting 2 and upper lid 3, institute
State lid 3 and be welded in pipe fitting 2, the straight tube 1 is copper and iron composite straight pipe, and the pipe fitting 2 is iron pipe part, and the pipe fitting 2 includes straight
Figure 211 and the flared section 212 for being connected to straight figure 211, the internal diameter of the flared section 212 are more than the external diameter of straight tube 1, described straight
One end of pipe 1 is plugged in flared section 212 and welded with flared section 212, the welding of straight tube 1 and pipe fitting 2 is more consolidated, uses
Resistance welding efficiency high, energy-conserving and environment-protective, quality is stabilized.The utility model is combined by copper and iron composite straight pipe and iron pipe fitting welding,
Upper lid 3 is welded in iron pipe part, forms complete exhaust pipe structure, and its reasonable in design reduces the use of copper material, reduction production
Cost, improves production efficiency, and quality is stable.
In the present embodiment, changeover portion 213 is provided between the straight figure 211 and flared section 212, the upper lid 3 is set
There is the mating holes coordinated with changeover portion 213, be easy to the welding of pipe fitting 2 and upper lid 3, upper lid 3 and the electric resistance welding of changeover portion 213.
In the present embodiment, the straight figure 211, changeover portion 213 and the integrated molding of flared section 212 are easy to the life of pipe fitting 2
Production manufactures and structure is more stablized, reliable operation.
In the present embodiment, the outer surface of straight tube 1 is provided with heat dissipating layer, is easy to distributing for heat in straight tube 1.
In the present embodiment, the copper and iron composite straight pipe include irony middle level 11, be coated on it is copper outer outside irony middle level 11
Layer 12 and the interior copper internal layer 13 being affixed in irony middle level 11, reduce the use of copper material, with low cost, reliable operation, weldability
The excellent, production efficiency of energy is high, environmental protection, and with good wearability, corrosion resistance and processing performance.
Copper and iron composite straight pipe is that copper and iron composite plate material is squeezed through disposable punch forming either copper pipe and iron pipe through disposable
