Description

The lined ceramic wear-resistant pipe is a new type of wear-resistant pipe that uses a special process to firmly combine the ceramic and the metal pipe, and uses the high strength and high hardness of the wear-resistant ceramic to increase the wear resistance. It can greatly improve the service life of the pipeline.

The lined ceramic wear-resistant pipe has the characteristics of high strength, good toughness and impact resistance. Welded steel pipes and corundum ceramics have high hardness, wear resistance, corrosion resistance and heat resistance, which overcomes the problem of low hardness. Therefore, the ceramic wear-resistant pipe has excellent induction functions such as wear resistance, heat resistance, corrosion resistance, mechanical and thermal shock resistance, and good weldability.

Ceramic sleeve lined manufacture details

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.

Feature

1. Wear resistance:
The lining ceramic of the wear-resistant ceramic tube is mainly made of high-purity alumina, which is made of ceramic material through a special sintering process.

2. Corrosion resistance:
Wear-resistant ceramics are stable α-alumina calcined from alumina powder at a high temperature of around 2000 °C. They are chemically stable, not easy to react with acid and alkali, and can resist most acid and alkali corrosion.

3. High temperature resistance:
The wear-resistant ceramics are originally sintered in a high temperature environment, and the lining ceramics can work normally in an environment above 1000 degrees, but the wear-resistant ceramic tubes are bonded with ceramics and steel pipes through adhesives. At the same time, the high temperature resistance of the adhesive limits the temperature resistance of the pipe, so the temperature resistance range of the general wear-resistant ceramic pipe is -20℃-500℃. The wear-resistant ceramic tube produced by mechanical self-locking or integral molding avoids the limitation of adhesives and can withstand high temperatures of 1000 °C.

4. Erosion resistance:
The wear-resistant ceramic tube lined with ceramic has high smoothness and small connection gap, and has good durability against large particle erosion and gas dust erosion.

5. Light weight, saving manpower and material resources:
Compared with high-chromium cast iron and cast stone pipes, wear-resistant ceramic pipes have low density and light weight. Installation, transportation and maintenance are convenient, reduce the load of the support and hanger, and save manpower and material resources.

Application
Ceramic lined wear-resistant pipes can be widely used in electric power, metallurgy, mining, coal, chemical and other industries, as a medium for conveying sand, stone, coal powder, ash, aluminum and other materials.

Ceramic sleeve

Recently 95% alumina ceramic sleeve lined pipes, elbows and T pipes have been largely applied in lithium battery material conveying system. The main raw material of wear resistant ceramic sleeve 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 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.

In addition, the flatness of ceramic casing is also an important factor affecting the size of lithium battery materials.We did a lot of analysis and improved our manufacturing techniques to solve both of these problems. Now it can help lithium battery delivery systems better solve these problems, with better material purity, longer service life and better economic benefits.

Process

Removing rust and decontamination process of outer-layer steel pipe;

Must be in strict accordance with the prescribed ratio, the binder ab 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;

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;

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;

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 1×45° 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;

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.
