Aluminum Oxide (Al2O3) Ceramics are a type of advanced ceramic material that is known for its high strength, hardness, and excellent wear resistance.Download PDF
By cold isostatic pressing process, aluminum oxide ceramics have the advantages of high hardness and abrasion resistance,defined and uniformly low erosion,dimensional stability and low specific weight.
Alumina ceramic lined pipe and elbow are widely used to protect wherever highly wear resistance are required,such as machines and systems of steel plants, foundries, mining, processing and preparation of minerals, within the paper, pulp, chemical and lithium battery industries, in power plants (coal, wood and solid fuels), in cement production, and in concrete production and transportation.

Large diameter ceramic tubes are used in various industrial applications due to their unique properties such as high temperature resistance, chemical inertness, and strength.
The main raw material of wear resistant ceramic ring is a special kind of ceramic with AL2O3 as the and the rare metal oxide as the flux, which is melted by high temperature at 1700 °C. The Ceramic Sleeves Lined Pipe as a whole part, and then assemble it into the steel pipe with our high-strength-temperature-resistant epoxy adhesive.
Recently 95% alumina ceramic sleeve lined pipes, elbows and T pipes have been largely applied in lithium battery material conveying system. The big diameter ceramic sleeve is always a big problem for the ceramic tube manufacturers since it’s very difficult to control the deformation rate of the ceramic sleeve after it’s sintering .Also It will also need an advanced and big isostatic pressing machine to do this .So it will not only express the company’s production capability ,but company’s technology. Right now, our factory have owned both advantages which are wear resistant ceramic pressing facilities and technologies.

Ceramic sleeve lined pipe has a continuous ceramic liner covering the inner surface of the pipe. The ceramic liner, or sleeve, is typically made of high-quality alumina ceramics, which provides excellent resistance to wear, abrasion and corrosion.
Ceramic sleeve lined pipes are commonly used in industrial applications where the pipeline is exposed to harsh conditions, such as in mining, power generation, oil and gas, and chemical processing. The ceramic sleeve provides superior wear resistance and protects the underlying steel pipe from premature failure due to abrasion or corrosion.
In addition to their excellent wear properties, ceramic sleeve lined pipes may also provide benefits such as improved flow rates, lower maintenance costs, and longer service life. They may also be used in applications where hygiene is important, as the ceramic sleeve lining is non-toxic and does not react with most chemicals.
Ceramic sleeve lined pipes may be manufactured in various sizes and shapes, including elbows, tees, and reducers, to meet the specific requirements of each application. The ceramic sleeve may be bonded to the steel pipe using specialized adhesives and may be installed using conventional welding or mechanical joining techniques.
While ceramic sleeve lined pipes can offer significant benefits in terms of wear resistance and longevity, they are typically more expensive than traditional steel pipes due to the cost of the ceramic liner and specialized manufacturing processes.
Ceramic pipe sleeves are a type of ceramic lining designed to protect metal, plastic or composite piping systems from wear and abrasion caused by high-velocity flows of abrasive materials. They are typically made of highly engineered ceramic materials such as alumina or silicon carbide, which provide excellent resistance to wear, corrosion, and erosion.
Ceramic pipe sleeves are widely used in industries such as mining, power generation, and chemical processing where the harsh environment can cause significant wear and damage to the piping systems.
The advantages of using ceramic pipe sleeves include:
Overall, ceramic pipe sleeves are an effective and reliable solution for protecting piping systems from the harsh effects of abrasive materials. They offer superior wear resistance, corrosion resistance, and improved efficiency compared to traditional materials, reducing maintenance costs and improving system performance.

Abrasion resistant pipe using steel skeleton packaging, and the two ends of the pipe with plastic head, to prevent dust and rain into the pipeline inside, to ensure the beauty of the product.
For different production environments, our company has developed a wear-resistant pipe for a variety of media, based on the temperature, wear and corrosion requirements of the field media, and for the initial application of the scene, our company to provide wear-resistant ceramic ring for the Lined composite straight pipe design to meet the on-site wear resistance, heat resistance and corrosion resistance requirements, in view of this program for the new design (formerly ceramic chip technology, there are many gaps, easy to wear).
After the ceramic ring in the pipe is installed and the thread is processed, the dirt outside the pipe is cleaned, and the outer surface of the pipe is treated with three layers of anticorrosive paint to meet the export requirements.
