The backpack-type ceramic elbow is a kind of ceramic tile lined pipe bend, also known as the reinforced elbow. In the position where the elbow is seriously impacted, a layer of the anti-wear backpack is added, and the alumina ceramic is pasted on the inner wall of the pipe with inorganic adhesive. , After curing, a firm wear-resistant layer is formed. The backpack-type ceramic elbow realizes double-layer wear resistance and is suitable for places with serious wear. The ceramic tile lined pipe bend is generally used in steel, thermal power, chemical industry, mining, cement, coal mine, coal washing Pulverized coal conveying system, and dust removal systems.
Ceramic technical parameters
|Content of alumina||≥95%|
|Rockwell A hardness||≥85HRA|
|Impact strength||≥1500 MPA|
|Thermal expansion coefficient||7.2×10-6m/m.K|
Super wear-resistant: The wear-resistant ceramic backpack elbow has double-layer wear-resistant characteristics, and the hardness reaches above HRA88, which is more than 10 times wear-resistant than ordinary pipes.
High temperature and corrosion resistance: It can run at 350 ℃ for a long time, and is resistant to acid and alkali corrosion and oxidation.
Shock resistance and thermal expansion and contraction: The thermal expansion coefficient of viscose is between steel and ceramics, which can well adjust the extrusion of ceramics due to the inconsistency of thermal expansion between ceramics and steel.
Erosion resistance: It can resist the erosion of larger particle materials without breaking.

The production process of a ceramic tile lined pipe bend :
Ceramic tube production: Al2O3 ceramics: have high alumina content, relatively dense structure, and special properties, so they are called special ceramics. Al2O3. The ceramic material is a close-packed hexagonal structure composed of oxygen ions, and aluminum ions are filled in two-thirds of the octahedral gap, which is the same stable α-Al2O3 structure as natural corundum, so the ceramic has a high melting point, high hardness, and excellent wear resistance. The hardness of the ceramic patch is ≥HRA85, second only to the hardness of diamond, and the surface is smooth and the friction coefficient is small, and the wear resistance is very ideal, especially in high-temperature oxidizing media or corrosive media.
Steel body production: According to the drawings or design drawings, the cylinder block is assembled in sections. Generally, the bending radius is designed to be more than 5d to reduce the impact force of the pipeline medium.
Ceramic tube assembly: The gap between the ceramic tube and the steel part is controlled between 1-2mm. The key is to control the concentricity and misalignment rate so that the ceramic and the steel part are completely bonded.
