Abstract

The invention discloses a corundum pipe bend which comprises ceramic composite steel pipe bend end faces. Nut connecting openings are formed in each ceramic composite steel pipe bend end face. The ceramic composite steel pipe bend end faces are mounted at the two ends of a seamless steel pipe bend. Reinforcement ribs are arranged on the surface of the seamless steel pipe bend. The seamless steel pipe bend is formed by a corundum layer, an aluminum oxide ceramic layer and a steel plate layer. The corundum layer is mounted on the inner surface of the aluminum oxide ceramic layer. The aluminum oxide ceramic layer is annularly mounted in the steel plate layer. The corundum pipe bend is designed based on the arched self-embedding principle, a 36-degree mechanical self-supporting structure is formed by ceramic blocks, conical design is adopted, the ceramic blocks lock one another, and it is effectively guaranteed that the ceramic blocks do not fall off; clearances between the ceramic blocks and the inner wall of the steel plate layer are filled with high-temperature bonding fire clay capable of resisting the temperature being 1,100 DEG C, and therefore dual protection is achieved; and the ceramic blocks and the steel plate layer are fixed through a high-molecular binder, and the bend can bear large impact force generated by materials and be used under high working conditions.

Description

technical field [0001] The invention relates to the technical field of corundum pipe fitting elbows, in particular to a corundum pipe fitting elbow. Background technique [0002] With the rapid development of my country's economy, pipeline transportation has spread to power, metallurgy, petrochemical, coal and other industries. When pipelines transport ash, pulverized coal, ore concentrate and other abrasive materials, there is pipeline wear. Fast problem, especially the elbow wears faster. When strong corrosive gas, liquid, or solid is transported in the pipeline, there is a problem that the pipeline is corroded and damaged. When the material with higher temperature is transported in the pipeline, There is a problem that the use of heat-resistant steel pipes is expensive. Therefore, the country is in urgent need of a pipeline that can resist high temperature corrosion, high temperature erosion and wear, especially the elbow used for connecting pipelines. SUMMARY OF THE INV...
