Wear resistant alumina ceramic rings

Wear resistant alumina ceramic rings are ceramic components specifically designed to withstand wear and abrasion in various industrial applications. These rings are made from alumina ceramic, which is known for its high hardness and wear resistance.

Features of Wear Resistant Alumina Ceramic Rings

1. High Hardness: Alumina ceramic rings exhibit exceptional hardness, making them resistant to wear and abrasion.
2. Wear Resistance: These rings are designed to withstand the harsh conditions of abrasive environments, maintaining their integrity and shape.
3. Chemical Inertness: Alumina ceramic is chemically inert, providing resistance to corrosive substances and chemicals.
4. Thermal Stability: Alumina ceramic rings have excellent thermal stability, allowing them to withstand high temperatures without deformation or degradation.
5. Low Friction Coefficient: The low friction coefficient of alumina ceramic reduces friction and wear in applications where sliding or rotating movements are involved.
6. Electrical Insulation: Alumina ceramic rings possess excellent electrical insulation properties, making them suitable for electrical applications.

Applications of Wear Resistant Alumina Ceramic Rings

• Pump Components: Alumina ceramic rings are used in pump systems as wear-resistant components, such as plungers and sealing rings.
• Mechanical Seals: These rings are utilized in mechanical seals to provide wear resistance and sealing capabilities in rotating equipment.
• Valve Components: Wear resistant alumina ceramic rings can be found in valve assemblies, helping to reduce wear and extend the lifespan of the valves.
• Bearing Systems: Alumina ceramic rings are used in bearing systems to reduce friction and wear in high-speed or high-load applications.
• Cutting Tools: They can be incorporated into cutting tools to enhance their wear resistance and extend their tool life.

It's important to note that the specific design and dimensions of wear resistant alumina ceramic rings can vary depending on the application and requirements. Consulting with manufacturers or suppliers specializing in ceramic components is recommended to ensure the best fit for your specific needs.

Packaging and delivery of Ceramic sleeve lined pipe

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.

Process of ceramic sleeve lined pipe

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).

Paint process

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.

For the convenience of customers, are to provide a more specific process is as follows:

1. Removing rust and decontamination process of outer-layer steel pipe;
2. Must be in strict accordance with the prescribed ratio, the binder a\b accurate measurement, with how many, must be stirred evenly, full stir-mixing must not be less than 4 times, such as adding a mixture of the embedded feed should be mixed with the binder and then add the mixture to stir up not less than 3 times;
3. The binder is applied evenly on the inner wall of the steel tube to ensure the thickness is not less than 0.5mm thickness. Then apply the binder on the outer surface of the ceramic ring to ensure the thickness between the 0.5mm-1mm. Also in the ceramic ring side (with the ceramic ring contact with the corresponding surface) Daub 0.5mm Adhesive, to ensure that after the installation of the ring and the seal between the ring;
4. After the installation of the ceramic ring in place, it is necessary to repair the gap between the assembled ceramic rings and mend the joints to ensure the sealing between the ring and the ring;
5. According to the NPT standard, we process the two pipe ends of male and female thread processing. The end of the pipe processing, and processing 1x45° groove, to prevent on-site installation in the process of cutting the hands of construction workers, do a good job of safety protection measures, thread processing, need to brush oil to protect the thread;
6. After installing the ceramic ring, check the internal surface of the ceramic ring of the formation, finishing in place, cannot move the position of the pipe, because the binder is not dry, vibration is easily caused by the displacement of ceramic rings, affect the use of the effect of cold weather in winter, binder drying time is longer, need to ensure more than 48 hours.
