In the electric power, metallurgy, chemical industry, mining, cement, paper-making and other industries, because the conveying medium for conveying equipment wear-resistant requirements are relatively high, ordinary steel pipe cannot meet the actual use needs, which requires better wear-resistant conveying equipment.
+ Wear-resistant ceramic ring / Al2O3 Alumina Ceramic Tube
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).
Wear-resistant ceramic ring Weld
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.

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.

Packaging:
Pipe fittings 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.

Relevant technical introduction of wear-resistant ceramic ring
The wear resistant ceramic ring is a special kind of ceramic with Al2O3 as the main raw material and the rare metal oxide as the flux, which is melted by high temperature at 1700 oC.
Ceramic lined inner details
Features:
1. The wear-resistant ceramic ring has the characteristics of smooth interior wall and super wear resistance. Widely used in chemical, fine powder conveying pipelines and other industries, with high wear-resistant and anti-corrosion functions.
2. In accordance with the traditional process, the production of wear-resistant ceramic ring is mainly the use of hot-pressing casting or grouting molding. Adopting isostatic pressing forming technology, the ceramic ring with isostatic pressing is better in compactness and more accurate in ceramic size.
3. At present, our ceramic ring lining pipeline in the silicone industry, chemical industry, fine powder conveying industry has been widely used.
Ceramic Tubes
These Ceramic Tubes are identical to the ones we use in our production, so high quality, consistency, and uniformity are assured.
