Pneumatic ash conveying pipelines in thermal power plants are seriously worn, resulting in fly ash everywhere, which not only affects production but also causes great pollution to the environment. In the past, we generally used this to reduce the air pressure during soot blowing. This reduces wear and saves energy. Although this method can prolong the life of the ash conveying pipeline a little, it cannot fundamentally solve the wear and tear problem.   Pneumatic ash removal pipelines are seriously worn. Generally, there is a problem with the material selected for the pipeline. Wear-resistant materials are required. It is recommended to use wear-resistant ceramic elbows. The wear-resistant ceramic elbow is manufactured with high-tech production technology. The wear-resistant ceramic elbow comprises three layers of corundum ceramic, a transition layer, and steel from the inside to the outside. The ceramic layer is formed at a high temperature above 2200 ℃. , form a firm bond with the steel pipe through the transition layer.   The wear-resistant ceramic elbow produced by our company has a lifespan of dozens of times that of ordinary elbows. It has good wear resistance, heat resistance, corrosion resistance, mechanical and thermal shock resistance, and good weldability. It is an ideal wear-resistant and corrosion-resistant pipeline such as material, grinding and corrosive media, which is not easy to age and fall off.   Due to the wear-resistant, corrosion-resistant, and heat-resistant properties of wear-resistant ceramic elbows, they can be widely used in electric power, metallurgy, mining, coal, chemical, and other industries to transport sand, stone, pulverized coal, ash, aluminum liquid, etc. It is an ideal anti-corrosion elbow.

Application of wear-resistant ceramic pipes in the metallurgical power industry: Metallurgy and power industries need to consume a lot of metal pipes to transport coal powder, ash, mud, and lime gypsum slurry, etc. The use of ceramic composite pipes to replace different pipes has high wear resistance, long service life, convenient installation, and significant economic benefits.   2. Application of wear-resistant ceramic pipes in mining and coal industries: (1) Mine: Mine filling, concentrate and tailings pipelines are seriously worn.   (2) Coal: Coal preparation and long-distance pipeline transportation generally adopt wet transportation. The delivery pipe is required to be both wear-resistant and corrosion-resistant. The pipe can be used as a long-life delivery pipe with considerable economic benefits.  

Wear-resistant pipes are mainly used for material conveying pipes such as pneumatic and pumping slurry. Transmission has spread all over the electric power, metallurgy, coal, petroleum, chemical, building materials, machinery, and other industries, and is developing at a high speed. Wear-resistant pipes are widely used in coal-fired thermal power plants for powder feeding, slag removal, ash transport, filling materials, ore concentrate, and tailings transportation systems that are severely worn.   Wear-resistant pipe materials are classified as follows: Rare earth wear-resistant alloy tube: the material is rare earth wear-resistant alloy steel; Bimetal wear-resistant composite pipe: the material is 20#+ high chromium alloy; Tortoiseshell high temperature wear-resistant composite pipe: the material is 20#+ corundum high wear-resistant lining material; Wear-resistant ceramic patch tube material: 20#+ aluminum oxide patch or silicon carbide; Sintered ceramic tube material: 20#+ aluminum oxide; Steel rubber wear-resistant pipe material: 20#+ wear-resistant rubber; Steel-plastic wear-resistant pipe material: 20#+ PTFE or polypropylene; UHMWPE composite pipe material: 20#+UHMWPE; Wear-resistant cast stone pipe material: 20#+ cast stone, etc.   Wear-resistant ceramic tube performance: Wear-resistant ceramic composite pipes quickly occupy the market, in addition to high quality and good performance, but also because their cost performance is higher than other wear-resistant, corrosion-resistant, and heat-resistant pipes. In terms of wear-resistant pipes of the same specification and unit length, the weight of wear-resistant ceramic composite pipes is only half of that of wear-resistant alloy cast steel pipes, and the project cost per meter is reduced by 20%-30%; only one-third of the weight of cast stone pipes First, reduce the project cost by 5%-10% per meter; the cost performance is more outstanding, in contrast, everyone is more willing to choose alumina ceramic lined pipes.

Abrasion-resistant pipes are widely used in various industries. Among them, in the new energy lithium battery industry, stainless steel ceramic elbows or straight pipes are often used. According to the different working conditions and environments of the product, the curvature radius of the elbow, the length of the pipe, the thickness of the ceramic material, and the size of the steel pipe are also different. Each design is very important. The role of pipes.   In the ceramic wear-resistant elbow used in the powder feeding pipeline of the power plant boiler, the curvature radius of the elbow is determined according to the requirements of the drawings, generally 6-10 times the curvature. To effectively alleviate the wear degree of the pipeline, the design curvature should be used as much as possible. An elbow with a larger radius has a longer service life.   When the tailings slurry is transported in the mining industry, the radius of curvature of the wear-resistant elbow is generally between 2D and 5D, which can achieve better results.   When transporting pulverized coal pipelines in cement and coal lines, Abrasive elbows are often used with a radius of 10D-15D, which can ensure the smooth transportation of the powdered materials. In this way, the wear and tear on the pipelines will be higher. Small.   Therefore, it is very necessary to design reasonable wear-resistant ceramic elbows for different working conditions. Reasonable design can maximize the wear resistance of ceramics. Increase the service life of pipes.  

The pipeline is a standard delivery system equipment used to transport various raw materials and substances, which is equivalent to blood vessels in industrial production. However, due to the flow and friction of materials and the importance of the pipe, the pipe wall may be damaged, so there is a need for a long-lasting wear-resistant pipe. Different types of wear-resistant pipes have different materials and different applications. Abrasion-resistant piping materials fall into the following categories: 1. The main material components of metal wear-resistant pipes are generally wear-resistant steel, alloy materials, surfacing materials, etc., which can be used in various complicated industrial and mining industries such as continuous high-temperature coal ash pipes, tailings pond backfill soil mines, and coal preparation plant pipes. enterprise. Its stability is good, but its main disadvantages are relatively high cost and net weight. 2. The main component material of wear-resistant ceramic pipes is silicon carbide or aluminum oxide, which can be used in high-quality transportation systems such as lithium batteries and silicon slag. It can also be used in working conditions with greater impact and wear. Wear-resistant ceramic pipes have good wear resistance, corrosion resistance, high temperature, and low-temperature resistance, are lightweight, and are currently widely used wear-resistant pipes. 3. High-molecular polyethylene wear-resistant pipes are mainly used for cement mortar transportation. It has the advantages of low cost, smooth inner wall, and good corrosion resistance, but it is not heat-resistant and cannot transport coarse particles or dry materials. Different wear-resistant pipes can be used in different working conditions and have different effects. You can choose suitable wear-resistant products according to different working conditions.  

Wear-resistant ceramic liners have solved the problem of anti-wear for many heavy-wear fields such as steel mills, power plants, and cement plants, protected equipment, reduced maintenance costs, and to a certain extent can save time, improve efficiency, and even improve product quality. However, many heavy-wear areas are also accompanied by high-temperature conditions. Under such conditions, the ordinary wear-resistant ceramic installation method will become very unstable and prone to porcelain falling off. The wear-resistant ceramic liner with a dovetail slot solves the problems of wear and impact in high-temperature environments, it can run stably at a high temperature of 750°C through practical tests.   What is dovetail alumina ceramics? Dovetail wear-resistant ceramics for card slots are a special shape of ceramics, that can be fixed to the equipment by mechanical force without the use of ceramic glue, stud welding, and other installation methods.   How to install dovetail wear-resistant ceramics? When installing, first weld a dovetail guide rail on the wear area of the equipment, and then interlock the dovetail wear-resistant ceramic slot with the guide rail to form a mechanical self-locking force to complete the installation.   What are the advantages of a dovetail ceramic lining board? 1. High-temperature resistance, stable operation without falling off: the wear-resistant ceramics of the dovetail card slot are installed and fixed by mechanical force, will not be affected by high temperature, and can run smoothly even at high temperatures of seven to eight hundred degrees. 2. Wear resistance: The wear-resistant ceramics of the dovetail card slot only change the shape of the ceramics, and the high hardness and wear-resistant properties of the ceramics themselves have not changed, and the wear-resistant effect is excellent. 3. Impact resistance: Due to its special shape, the wear-resistant ceramics of the dovetail card slot are often thicker, so they have strong impact resistance.   What fields are wear-resistant ceramic liners for dovetail slots suitable for? The production process of dovetail ceramics is relatively complicated and the cost is high, so it is rarely used in ordinary occasions, and most of them are used in high-temperature conditions, such as thermal power plants and steel plants.
