Analysis of the process and application of the production of ceramic lined steel pipes 1IntroductionCeramic-lined steel pipe is a special pipe with wear resistance, corrosion resistance and high temperature stability.
It adopts an advanced manufacturing process to enhance the service life and corrosion resistance of the steel pipe by coating a layer of special ceramic material on the inner wall of the steel pipe.
2.Process flow 21. Surface treatment of steel pipesThe first step in the production of ceramic-lined steel pipes is to treat the surface of the steel pipe to ensure the firmness of the adhesive layer.
Sandblasting or pickling is usually carried out to remove oxides and impurities on the surface of the steel pipe, making it smooth and clean.
2.2. Preparation of ceramic adhesive: The preparation of ceramic adhesive is an important step to ensure the strong bond between the ceramic layer and the steel pipe.
Organic adhesive is usually used for bonding to ensure that the ceramic material can be evenly adhered to the inner wall of the steel pipe.
2.3. After the ceramic material is bonded, it is evenly coated on the inner wall of the steel pipe by spraying.
The coated ceramic materials are usually materials with high hardness and high wear resistance such as alumina and zirconia, which have excellent corrosion resistance.
2.4. The ceramic-lined steel pipe after hardening and sintering coating is hardened and sintered to make the ceramic material firmly bonded to the inner wall of the steel pipe and improve its hardness and wear resistance.
In the process of hardening and sintering, it is necessary to strictly control the temperature, time and other parameters to ensure the quality of the ceramic-lined steel pipe.
3.Feature 31. Wear-resistant ceramic-lined steel pipe has excellent wear resistance and can maintain a long service life under the scouring of high-speed fluid.
Its surface hardness is high, which can effectively resist the wear and erosion of solid particles.
3.2. Corrosion-resistant ceramic-lined steel pipes perform well in corrosive media such as strong acids and alkalis.
Ceramic materials have good chemical stability, which can resist corrosion and erosion, making the piping system more durable.
3.3. High temperature stability: ceramic lined steel pipe, which can operate stably for a long time in a high temperature environment.
The ceramic material has excellent heat resistance, which can ensure the safe operation of the piping system under high temperature conditions.
4.Application area 41. Ceramic lined steel pipes in mining and metallurgical industry are widely used in conveying systems in mining and metallurgical industries.
In the process of handling granular materials such as ore and slag, ceramic lined steel pipes can effectively reduce the wear and clogging of pipelines.
4.2. In the chemical field, ceramic lined steel pipes are widely used in the chemical field.
Due to its excellent corrosion resistance, it can effectively resist the erosion of chemicals and ensure the safe operation of the pipeline system.
4.3. Ceramic lined steel pipes in the power industry are also widely used in the transmission system of the power industry.
In the process of coal-fired and gas-fired power generation, ceramic lined steel pipes can reduce the wear and clogging of pipelines and improve the transportation efficiency.
Summary: As a kind of pipe with wear resistance, corrosion resistance and high temperature stability, ceramic lined steel pipe is widely used in mining, metallurgy, chemical industry and electric power industries.
Manufactured through advanced technology, ceramic-lined steel pipes have excellent performance and can improve the service life and safety of piping systems.
