Silicon carbide composite tube for zinc-plating spiral hexsteel

Abstract

The invention relates to a composite tube, in particular relates to a silicon carbide composite tube for a zinc-plating spiral hexsteel. The silicon carbide composite tube for the zinc-plating spiral hexsteel comprises a light zinc-plating spiral reinforcing steel pipe, the hexsteel and a silicon carbide ceramic from outside to inside. The hexsteel is fixedly welded on the inner wall of the light zinc-plating spiral reinforcing steel pipe; the silicon carbide ceramic is filled in grids of the hexsteel; and a crest spiral reinforcing rib is adhered on an outer wall of the light zinc-plating spiral reinforcing steel pipe. The silicon carbide composite tube provided by the invention has the advantages of strong wear-resistance anti-impact toughness, good thermal shock resistance, high temperature resistance, lighter weight, convenience in installation and the like, and the circulation resistance is not increased.

Description

technical field [0001] The invention relates to a composite pipe, in particular to a galvanized spiral tortoise shell mesh silicon carbide composite pipe. Background technique [0002] In the existing technology, the traditional wear-resistant silicon carbide composite pipe is generally made of two structures: one is the outer steel pipe, the inner corundum ceramic patch; the other is the outer steel pipe, the middle layer of tortoise shell mesh, and the Grinding clay is filled in the tortoise shell mesh grid. The structure of the outer steel pipe and the inner corundum ceramic patch structure is large, and the construction quality is easily affected by human factors; secondly, since the corundum ceramic patch is attached to the inner wall of the steel pipe, once the ceramic patch falls off, it will cause a large area of ​​patch peeling off Phenomenon; Finally, the thermal shock resistance of the corundum ceramic patch is poor, and the coating of the corundum ceramic patch ...

AI Technical Summary

Problems solved by technology

The structure of the outer steel pipe and the inner corundum ceramic patch structure is large, and the construction quality is easily affected by human factors; secondly, since the corundum ceramic patch is attached to the inner wall of the steel pipe, once the ceramic patch falls off, it will cause a large area of ​​patch peeling off Phenomenon; finally, the thermal shock resistance of the corundum ceramic patch is poor, and the coating of the corundum ceramic patch is easy to crack and fall off under the condition of drastic temperature changes

The outer layer of steel pipe, the middle layer of tortoise shell net, and wear-resistant cement are used to fill the inner structure of the tortoise shell net grid, and the wear-resistant cement has poor wear resistance
