The backpack wear-resistant ceramic sleeve lined elbow is also called the reinforced ceramic sleeve lined elbow.Download PDF
The ceramic sleeve lined backpack ceramic elbow is based on the wear-resistant ceramic elbow, and a layer of anti-wear backpack is added. The special ceramic is pasted on the inner wall of the pipe with a high temperature resistant inorganic adhesive, and after heating and curing, it forms a strong anti-wear. Therefore, the wear-resistant ceramic backpack elbow realizes double-layer wear resistance, which is suitable for working conditions with serious wear.
The high alumina ceramics are installed onto the internal surface of the pipe properly by welding, pasting or inter-locking system. With the brilliant properties of resistance to wear, corrosion and heat, the pipe is widely used in materials handing of coal industry, electric power, metallurgy, mining and chemical industry and it is one ideal wear resistant pipe.
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.

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.
