Ceramic Sleeve Lined Pipe For Lithium Battery

Because the lithium battery industry needs to isolate metal pollution in material transportation, the wear resistance and insulation of the wear-resistant ceramic ring has become the best choice for the lithium battery industry.

Features

  1. Longer life time, reduce maintenance costs
  2. Higher cost performance
  3. Reduce pollution to raw materials
  4. Easy to disassemble and maintain

Benefits

  • The coal will bring great impact to the equipment during transportation in the coal handing system of power station, so the alumina ceramic tiles s not available and they will fall of by large area.
  • The valve in the desulfurization system can change the follow during the switching process, sot he slurry with grain at high speed will wear out the pipe at the ends of valves. The liquid in the tube contains much sulfite which is very corrosive, so usually nonmetallic pipes like rubber tubes and PVC pipes are used to avoid corrosion, but the wear resistance of these tubes are poor that the straight pipe at the ends of valves always worn out. The alumina ceramic lined tube/elbow is one piece, the slurry couldn’t permeate through it, moreover, the alumina tube/elbow has high hardness and the process by isostatic pressing dry power is favorable to the uniformity of ceramic crystal structure, so its wear resistance is better than ceramic tiles with the same materials.
  • The weakest place is the gap between each sticked tiles during material handing. The material grains not only wear the pipe but also have impact on it. This is why the pipelines lined by tiles are easily worn out and fallen off.
  • The experiment shows that the service life of ceramic tube/elbow is at least 5 times longer than ceramic tiles of the same thickness.

What is Ceramic Pipe Sleeve?

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.

What is Ceramic Pipe Sleeve

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.

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.

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.

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.

Measuring thickness of ceramic layer
Measuring length

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.
