This paper introduces the heat-resistant stainless seamless steel pipe. When there is more heat in the inner tube body, one part is transferred from the inner tube body to the cooling cavity between the inner tube body and the outer tube body, the other part is transferred from the support plate on the inner tube body to the diffusion plate, the diffusion plate contacts the outer tube body, so as to transfer the heat to the diffusion plate, and the diffusion plate contacts the outer tube body, so as to transfer the heat to the outer tube body, and both the support plate and the diffusion plate are provided With graphene coating, the heat transfer is accelerated. The outer circumference area of the outer tube body is larger than the outer circumference area of the inner tube body, so the heat dissipation is faster. At the same time, the heat temporarily stored in the cooling cavity can be dissipated to the outside through the holes of the connecting rings at both ends.
The new heat-resistant stainless seamless steel pipe divides the heat in the inner pipe into two ways to radiate outwards, with fast heat dissipation speed and high heat dissipation efficiency, effectively avoiding the corrosion of the inner wall of the seamless steel pipe, and prolonging the service life of the seamless steel pipe.
