Silicon Carbide Ceramic Sic Liner Plate for Abrasion Resistant Pipe
Product Description:
Silicon carbide bricks also called silicon carbide wear plates, silicon carbide lining plates, are a type of component that protects equipment. The use of silicon carbide bricks can reduce equipment wear, vibration and noise, and has the effect of anti-corrosion.
Silicon carbide bricks have high thermal conductivity, good wear resistance, thermal shock resistance, and corrosion resistance, so they are widely used in the industry. The most widely used is used as a wear-resistant liner in mining equipment.

Silicon Carbide VS Alumina:
Silicon carbide ceramics not only has excellent normal temperature mechanical properties, such as high bending strength, excellent oxidation resistance, good corrosion resistance, high wear resistance and low friction coefficient but also high-temperature mechanical properties (strength, creep resistance) is the best known ceramic materials. Hot pressing sintering, pressureless sintering, and hot isostatic pressing sintered materials, their high-temperature strength can be maintained up to 1600 ºC, is the best high-temperature strength of ceramic materials. The oxidation resistance is also the best among all non-oxide ceramics. Alias emery.
Alumina ceramics is a ceramic material with alumina (Al2O3) as the main body, used for thick film integrated circuits. Alumina ceramics have good conductivity, mechanical strength and high-temperature resistance. The wear life of silicon carbide ceramics is more than 10 times that of traditional steel products and alumina products.

Silicon Carbide VS Steel:
In many mines and mining processes, the system of powder making, ash slag, dust removal, and slag conveying, the equipment is constantly affected by the friction, corrosion, collision, impact and other factors of the medium during the operation of the equipment. The earliest wear-resistant material that can be used in large quantities is mainly wear-resistant steel, wear-resistant cast iron and other metal materials. After that, the newest silicon carbide products, which is superior to other wear-resistant materials in terms of wear resistance, corrosion resistance, practicability, and economy.

Industry application:
Silicon carbide plates are widely used in mining, ore crushing, screening, and transportation of high-wear and high-corrosive fluids. They are mainly used in copper mines, gold mines, iron ore, nickel mines and other non-ferrous metal mining equipment, use as a bushing, play a role of high wear resistance. Mine filling, ore concentrate and tailings transportation cause serious wear to the pipeline. The service life of the ore powder transportation pipeline used in the past is less than one year, and the service life of the silicon carbide products can be greatly improved.
Product Packaging:
We have two packaging methods, one is plywood box packaging, and the other is pure solid wood packaging. The pure solid wood packaging box will be certified for fumigation. We will choose the right packaging box according to the product.
The inside of the packing box is filled with foam. Generally, other companies use 2cm foam, but we choose 3cm foam and fix it with chain riveting. The outside is usually wrapped with packing tape to ensure the safety of product transportation.
Mining Industry Knowledge:
Selection criteria for silicon carbide lined pipes:
According to the nature of the conveyed materials and the different media conditions, it is important to choose products suitable for their own working conditions. When selecting wear-resistant materials, you must first determine your own working conditions, including the hardness of the conveying material, particle size, flow rate, conveying volume, conveying medium, etc., and then select the appropriate wall thickness silicon carbide wear-resistant material according to the specific situation.
