The wear-resistant ceramic composite pipe fully utilizes the weldability of the steel pipe and the high hardness, high wear resistance, corrosion resistance, and high temperature of the corundum ceramics. It is widely used in electric power, metallurgy, mining, coal, chemical, and other industries. It is an ideal wear-resistant and corrosion-resistant pipeline for sand, stone, coal powder, ash, aluminum liquid, and other abrasive granular materials and corrosive media.
Ceramic-composite pipes can be divided into the following types according to different production methods.
Direct adhesive wear-resistant ceramic composite pipe: The ceramic patch is lined with the inner wall of the pipe. The manufacturing process is simple, the cost is relatively low, and collision is avoided during ceramic installation and transportation. Ceramic patch pipes are commonly used in an environment where construction is relatively simple and works at normal temperatures (100-150 ℃).
Spot-welded card-type wear-resistant ceramic composite pipe: It is suitable for making large-diameter pipes. Paste ceramic orifice plates and weld iron bowls or studs to pipes. This double-layer connection is stronger and the service life of the pipes is longer. But it is more troublesome to make and the cost is higher.
Integral ceramic composite pipe: The integral ceramic ring is lined in the pipe, the inner wall is smooth and does not block the material, and has good wear resistance and corrosion resistance. Compared with the patch-type pipe, it is more durable and the cost is slightly higher.
According to the comparison of the above wear-resistant ceramic pipes, we choose the appropriate wear-resistant ceramic pipes according to the environment and needs of the pipes.
