Large-diameter abrasion-resistant ceramic pipes are mainly used to transport liquid-solid two-phase fluids and particles of corrosive media, as well as pneumatic transportation with severe erosion. They are used to replace expensive stainless steel pipes, high-chromium cast steel pipes, and hard alloy pipes. The product is cost-effective High, Ibeinuo provides customers with various alumina wear-resistant ceramic pipes, including straight pipes, elbows, reducers, tees, special-shaped pipe fittings, etc., and supports product customization.
The large diameter abrasion resistant ceramic pipe uses strong glue to paste the ceramic pieces on the inner wall of the pipe in dislocation. After curing, a firm anti-wear layer is formed. The wear-resistant ceramic patch composite pipe can operate at 350 °C for a long time.
The construction of large diameter abrasion resistant ceramic pipe is more convenient than that of small-diameter pipes, but if the ceramics are not firmly attached, they are easily washed away by the conveying medium inside the pipe due to excessive flow velocity. Therefore, the larger the diameter, the higher the requirements for technical requirements and production processes.

In addition to the conventional CNC lathe, the CNC machining center also has a sand wire cutting machine and an engraving machine to meet the production of complex structural parts. It can process and cut isostatic ceramic rings and can provide customers with wear-resistant pipes, wear-resistant bends Production of pipes, and various structural parts.
Products Feature
Large diameter ceramic patch composite pipe lined with alumina ceramic sheet is a special corundum ceramic made of AL2O3 as the main raw material, rare metal oxide as a flux, and calcined at a high temperature of 1700 degrees. It is formed by dry pressing and isostatic pressing and fired at high temperatures. The Rockwell hardness is HRA88, which has the characteristics of wear resistance, impact resistance, and convenient construction, which can effectively prolong the service life of various equipment. Common specifications of alumina ceramic sheets: 10*10*3-10, 17.5*17.5*3-15, 20*20*4-20, and can also be customized according to customer requirements.
Application and classification of wear-resistant pipeline lining ceramics
According to industry classification: wear-resistant pipeline lining ceramics are mainly used in industries with severe wear and tear of material conveying systems such as steel, thermal power, cement, coal, mining, chemical industry, smelting, machinery, lithium batteries, ports, coal washing plants, construction machinery, and organic silicon.
According to the classification of conveying medium: ceramic composite pipes can be divided into wind-conveying pipes and slurry-conveying pipes
According to the classification of conveying temperature: ceramic-lined steel composite pipe can be divided into a normal-temperature elbow and a high-temperature elbow;
Classified according to the purpose of the pipeline: ceramic-lined carbon steel pipes can be divided into powder pipelines, gas pipelines, water pipelines, oil pipelines, slurry pipelines, etc.;
Classified according to the material of the pipe: stainless steel, carbon steel, alloy steel, rubber, polyurethane, alumina ceramics, etc.;
According to the pressure classification of the pipeline: it is divided into the low-pressure pipeline, medium-pressure pipeline, high-pressure pipeline, and ultra-high-pressure pipeline.
1. The engineering pressure of the low-pressure pipeline is less than 1.6MPa;
2. The pressure of medium-pressure pipeline engineering is 1.6-6.4MPa;
3. High-pressure pipeline engineering pressure 6.4-10MPa;
4. The pressure of ultra-high pressure pipeline engineering is 10-20MPa.
