Ceramic wear-resistant pipe is a kind of special pipe widely used in mining, metallurgy, electric power and chemical industry. This article will introduce the classification of ceramic wear-resistant pipe.
The classification of ceramic wear-resistant pipe can be divided according to different characteristics. The following are some common classification methods:
1. According to the material points
Ceramic wear-resistant tube mainly has three kinds of alumina ceramics, zirconia ceramics and silicon carbide ceramics.
Alumina ceramics are widely used in engineering fields, and their high hardness and wear resistance make them ideal abrasive materials; zirconia ceramics exceed alumina ceramics in terms of hardness and wear performance, so they are used for high-strength mechanical parts; silicon carbide ceramics excel in high-temperature resistance and corrosion resistance, and they are an ideal special ceramic material.
2. According to the shape
Ceramic wear-resistant pipe shape variety, according to the different shapes can be divided into straight pipe, elbow, tee and so on.
Straight pipe can be divided into two types: plug type and integral type. The advantage of the plug type pipe is easy to disassemble, without disassembling the pipe can be replaced by the worn part; the whole pipe is suitable for the occasions with high requirements for sealing.
The shape of elbow and tee can be designed according to the direction of the pipeline, which can well meet the needs of the site.
3. According to the manufacturing process
Ceramic wear-resistant pipe manufacturing process also affects the performance of the pipe. The traditional manufacturing process is pressed molding, but the pipe manufactured by the existence of wear-resistant performance is unstable and ceramic cracks and other issues. The modern manufacturing process includes slurry molding, hot isostatic pressure molding, block welding molding and bonding molding and other processes, which can greatly improve the wear resistance of the pipe and extend the service life.
