Alumina Ceramic Mosaic Lined Pipe are the main parts of industrial piping, and are widely used in many industries, such as metallurgy, power, mining, coal, chemical, etc. experience serious wear and corrosion when transporting materials. Alumina Ceramic Mosaic Lined Pipe are widely used in these industries to greatly improve the service life and performance of the piping.
Shandong Qishuai Wear Resistant Equipment Co., Ltd. 's Alumina Ceramic Mosaic Lined Pipe have top wear resistance, the alumina ceramic lining has very high hardness and can reach a Mohs hardness of 9. The above-mentioned high hardness gives the product strong abrasion resistance and keeps good performance in abrasion resistance when being contacted with erosive materials with high hardness and high velocity for a long time, greatly extending the service life of the pipeline.
Speaking of it in detail, if we change our view to the microscopic world, due to the dense crystal and strong intermolecular bonding of alumina ceramic, it is able to resist the friction of material. Besides, the low friction coefficient is also one of the reasons why alumina ceramic lining pipe has excellent wear resistance. The inner wall of lining pipe is very smooth and its friction coefficient is more than 50% lower than that of ordinary steel pipe. Therefore, the material is transported more smoothly and the friction and wear of pipeline and energy loss are reduced.
In terms of chemical stability, the main component of alumina ceramic - aluminum oxide, will be sintered at high temperature to become a stable and dense crystal, and will not be corroded by many chemicals. No matter what strong acid, strong alkali or corrosive medium such as salt solution, Alumina Ceramic Mosaic Lined Pipe will not corrode.
In the transportation of acidic and alkaline wastewater in the chemical industry, traditional metal pipes will corrode and perforate for a short time, and then cause pipeline leakage and factory shutdown. Aluminum oxide ceramic mosaic line pipe has good corrosion resistance, and can stably run in the most extreme acid and alkali environment with pH value ranging from 1 to 14, and its service life is 3-5 times longer than that of ordinary metal pipe, which gives a solid guarantee for the safe production and stable operation of chemical enterprises.

Alumina Ceramic Mosaic Lined Pipehave good high temperature resistance and excellent thermal stability, can resist in the 1600℃ environment, still hold a good physical property and chemical property in high temperature circumstance. So they widely use in the high temperature field. When the temperature change rapidly, they can’t produce the large stress because of the thermal expansion and contraction. The phenomenon of deformation and cracking will not happen, and the piping system can use in the circumstance of a long time high temperature.
Raw Material Selection
Shandong Qishuai Wear Resistant Equipment Co., Ltd.always insist on the pursuit of excellence. In the manufacture of Alumina Ceramic Mosaic Line Pipe, we adhere to very high requirements for the selection of raw materials. We use high alumina powder with alumina content over 95%, and little impurities. This high alumina powder plays a decisive role in the excellent performance of our products, making our products have high hardness, very strong wear resistance and good chemical stability.
To make our customers have a better understanding of the high quality of our raw materials, we have added the test report data of the raw materials.

Mosaic Tile Application Process
In mosaic tile application process , we adopt unique and accurate technique. Firstly, ceramic tile is orderly assembled in mosaic form and the sequence arrangement avoids the impact force which the impact of material exerts to the inner wall of the pipe and enhances the wear-resistance of the pipe further more.
Perfect Integration with Steel Pipes
In the selection of steel pipe, we use high quality seamless steel pipe and national standard requirements, with high strength, high toughness and good weldability. The steel pipe is pretreatment such as rust removal, degreasing and phosphating before bonding with the ceramic lining. These pretreatment can improve the roughness and reactivity of the steel pipe, and enhance the bonding with ceramic lining.
Ceramic lining bonds with steel pipe by special composite process. The ceramic lining and steel pipe are combined together by effect of high temperature sintering and high strength adhesive. This method ensures the structural strength of whole pipe line. Meanwhile, the problem of detachment or loosening of ceramic lining during use will not happen.
When high-temperature sintering, chemical bond is formed between ceramic lining and steel pipe. The ceramic lining and steel pipe are combined together by effect of high temperature sintering. At the same time, high strength adhesive forms buffer and seal between ceramic lining and steel pipe. This greatly improves corrosion resistance and sealing of the whole pipeline.

Dimension Customization: We can definitely work on the products having non-fixed inner diameters, outer diameters and lengths as well. Suppose you are tying up for supply of pipes and there is no wide space available for fitting the pipes of specific lengths and dimensions, then we will work and make the products according to the dimensions given by you so that the equipment and pipes get matched perfectly.
Ceramic Material Customization: In addition to the commonly used 95% alumina ceramic, we can also make the inner lining of the ceramic material with different alumina purity (for example, 99% alumina or 92% alumina) according to the operating environment and requirements of the material, which makes the ceramic lining plate has better wear resistance, corrosion resistance and anti-high temperature performance.
Custom Connection Methods:There are various ways to connect the ceramic material to the equipment, such as welding, flange connection and quick connector fittings. You should choose the suitable method according to the connection method required by your equipment interface.
Shandong Qishuai Wear Resistant Equipment Co., Ltd. always takes product quality as the life of the enterprise. From raw materials to finished products, a complete quality inspection system has been established in multiple links.In the procurement links of raw materials, high-purity alumina powder is tested one by one. Alumina content, impurity items and particle size distribution are tested. Only when the material passes all the above tests can it be used for production. X-ray fluorescence spectrometers (XRF) are used to accurately analyze the chemical composition of raw materials, aluminum oxide content is always above 95%, and impurities are controlled to very low levels.
From the production process, strict quality control is carried out in every link. After ceramic patch coating, ultrasonic flaw detectors are used to check the bonding strength of ceramic patch and pipe inner wall, no loosening or delamination. In the final inspection link, the pipe is also checked one by one. The inner diameter, outer diameter and length of the pipe are measured accurately by coordinate measuring machine, and then the inner diameter, outer diameter and length of the pipe are checked according to the standard. Wear resistance is simulated by abrasion tester, and the wear rate of the product in the specified time is measured. The product is placed in the salt spray chamber to check the corrosion resistance in the acidic or alkaline environment..
