Ceramic Liner Pipe

The Ceramic Liner Pipe of Shandong Qishuai Wear-Resistant Equipment Co., Ltd. has become the trusted choice of numerous industries due to its outstanding performance. Every performance indicator has undergone careful design and strict testing, providing comprehensive protection for the stable operation of pipeline systems.

Wear Resistance

Wear is an extremely common and very difficult phenomenon in the operation of industrial pipeline. When the fluid containing solid particles flows out of the pipeline at a high speed, it is just as if there are countless pieces of sandpaper that can always rub against the inner wall of the pipeline. The inner wall of the general pipeline will be worn out gradually and even cause the pipeline to fail. According to statistics, in the industry of mining and electric power, the phenomenon of replacing pipelines frequently because of wear is very common. This phenomenon will increase the operating cost of enterprises and affect the continuity of production.

The Ceramic Liner Pipe of Shandong Qishuai uses ceramic materials with extremely high hardness and make our wear pipe that can effectively resist the erosion and wear of the solid particles. In terms of microstructure, when the solid particles collide with the surface of our wear pipe, the crystal structure of ceramic material is very dense and the chemical bond is very strong. When the solid particles collide with it, the ceramic material can resist the impact force, not easy to plastic deformation or deformation, and then break into small pieces, so that the wear resistance is very strong.

To intuitively demonstrate the wear resistance advantage of our wear pipe, we conducted a series of rigorous wear tests, and the test data are compiled into the following table:

It can be seen from the table that, when the test conditions are the same, the wear loss of ordinary steel pipe is 2.5mm, while the wear loss of Ceramic Liner Pipe of Shandong Qishuai is only 0.1mm, which has a very obvious anti-wear performance.

That is to say, the service life of pipelines will be extended for a long time when using our wear pipe and the pipelines need to be replaced more times, and a large amount of human resources, material resources and financial resources are saved for enterprises.

Corrosion Resistance

Shandong Qishuai's Ceramic Liner Pipe has good corrosion resistance. Ceramic materials are inorganic non-metallic materials with stable chemical properties and very weak chemical activity. When facing with corrosive medium, no chemical reaction will happen on the surface of our wear pipe, thus the medium will not erode the pipeline. It is applicable to strong acid such as sulfuric acid and hydrochloric acid, and strong alkali such as sodium hydroxide and potassium hydroxide.

High-Temperature Stability

Ceramic Liner Pipe of Shandong Qishuai has high temperature stability. Ceramic materials have high melting points and thermal stability, which can keep their physical and chemical properties in high temperature range. Usually, the high temperature range of our wear pipe can reach more than 1000℃. This is because the chemical bond has high energy, and the binding force between atoms is strong. When the temperature is high, it is not easy to occur lattice change and atomic diffusion.

Smooth Inner Wall

The inner wall of our wear pipe is very smooth, and its inner roughness Ra is 0.2 - 0.4μm. The smooth inner wall can significantly decrease the frictional resistance of the liquid flowing inside the pipeline. If you learn about fluid mechanics, you will know that the frictional resistance can be decreased by our wear pipe to increase the flow rate of the fluid and improve the transportation.

We have tested and summarized the data table below through the experience, the effect of our wear pipe in reducing the resistance and improving the efficiency.:

It can be seen from the table that after using our wear pipe, the fluid flow rate increases by 40% and the transportation energy consumption decreases by 20%. This not only saves enterprises a lot of energy costs but also improves production efficiency and enhances their competitiveness.

Professional Craftsmanship

Shandong Qishuai Wear-Resistant Equipment Co., Ltd. has always adhered to creating high-quality Ceramic Liner Wear Pipe products. From the strict selection of raw materials to the refined processing in the production process, and then to the quality inspection of the final products, every link embodies our professionalism and dedication, ensuring that customers receive our wear pipe with excellent performance and reliable quality.

Rigorous Material Preparation

Material selection is the basis for the quality of the Ceramic Liner Pipe. Shandong Qishuai strictly select the material and always pursue the perfect. The steel pipe we use are all from famous large iron and steel enterprise, Baoshan Iron & Steel Co., Ltd. and Anshan Iron & Steel Group Corporation. The steel pipe has good mechanical properties and corrosion resistance. The yield strength and tensile strength of these steel pipes are higher than national standard. It can provide strong structure support for pipeline.

We use high-purity alumina ceramic powder as the main raw material for ceramic, the alumina content of which is above 95%. This high-purity alumina ceramic has very high hardness and wear resistance. The hardness of ceramic is almost as hard as diamond, with Mohs hardness around 9, which is the second hardest after diamond. In addition, we add appropriate amount of fluxes and additives to improve the sintering performance and mechanical properties of ceramic, so that our wear pipe can keep the performance in different harsh environment.

Refined Steel Pipe Pretreatment

Because we use the high pressure water jet cleaning technology, which employ the impact of high speed flow water to clean oil, rust and other impurities on the inner wall of the steel pipe, make the inner wall of the steel pipe is clean.

The surface roughness of the inner wall of the steel pipe after cleaning can reach Ra 0.8 - 1.6μm, so that the inner wall of the steel pipe ready for our wear pipe have good bonding layer.

And then we remove the oxide scale and rust on the surface of the steel pipe by mechanical grinding and chemical derusting, make the surface of the steel pipe appears the bright metal.

The inner wall of the steel pipe after grinding is very smooth and flat. The surface roughness of the inner wall of the steel pipe after grinding can reach Ra 0.4 - 0.8μm. Our wear pipe's bonding strength on the steel pipe will be enhanced by this process.

To eliminate the residual stress generated in the production process of the steel pipe and enhance the toughness of the steel pipe, we also carry out appropriate heat treatment on the steel pipe.

Heat treatment process: Heat to certain temperature, retain for a period of time, then slow cooling until the temperature of steel pipe reaches the ambient temperature. Make the internal structure of the steel pipe more uniform and performance more stable.

Key Ceramic Material Preparation

The preparation of ceramic materials is a key link in our wear pipe production. According to different service environments and requirements, we adopt advanced formulas and preparation processes. High-purity alumina ceramic powder is mixed with an appropriate amount of fluxes and additives in precise proportions, and then put into a ball mill for ball milling. This ensures that various raw materials are fully mixed evenly, while the particle size is refined and the activity of the ceramic material is improved. The ball-milled ceramic powder has a uniform particle size distribution, with an average particle size of 5 - 10μm.

Then, the uniformly mixed ceramic powder is put into a high-temperature furnace for pre-sintering treatment, and the pre-sintering temperature is generally controlled between 1200℃ and 1300℃. Through pre-sintering, volatile impurities in the ceramic powder are removed, the crystal structure of the ceramic is stabilized, and a good foundation is laid for subsequent forming and sintering.
