The Main Classification Of Wear-resistant Ceramic Pipes

The classification of wear-resistant ceramic pipes mainly includes: spot-welded card-type wear-resistant pipes, patch wear-resistant pipes, integrated wear-resistant pipes, centrifugal casting composite pipes and ceramic-lined composite steel pipes.
The spot-welded card-type wear-resistant pipe is to paste the alumina ceramic sheet with a hole in the middle on the inner wall of the pipe with high-temperature-resistant strong adhesive, and at the same time cooperate with the spot welding process to firmly weld the ceramic to the inner wall of the steel pipe through the small hole. In order to protect the solder joints, a ceramic cap is screwed on it. Each piece of porcelain not only presses and inserts each other, but also forms a trapezoidal angle, so that the pieces of porcelain are closely connected without gaps. When the last piece of a circle is tightly embedded, a 360° mechanical self-locking force is formed between the porcelain pieces (this technique was used in Chinese bridge construction several centuries ago). The production process of this kind of product is relatively complicated, the production cycle is long, and the cost is high.
SMD wear-resistant ceramic pipe is to paste alumina ceramic sheet on the inner wall of the pipe with high-temperature-resistant strong adhesive, and form a firm anti-wear layer after heating and curing. The production process of this product is relatively simple, the production cycle is short, and the cost is relatively low.
The one-piece wear-resistant pipe is assembled by casting the pipe fittings as a whole and then pouring them inside the steel pipe with a special filling material. The inner wall of the pipe is smooth, has good sealing performance, and has good wear resistance and corrosion resistance. However, this kind of product has a long production cycle and high cost.
Centrifugal casting composite pipe is a composite pipe manufactured by "self-propagating high-temperature synthesis-high-speed centrifugal technology", which forms a uniform, dense and smooth ceramic layer and transition layer at high temperature and high speed. Because the manufacturing process is simple and the cost is low, it is suitable for long-distance powder transportation. However, its wear resistance is slightly worse than that of wear-resistant ceramic pipes, and it is generally used as a straight pipe.
Ceramic-lined composite steel pipe overcomes the low hardness, wear-resistant Defects such as poor performance and poor toughness of ceramics. Therefore, the composite pipe has good comprehensive properties such as wear resistance, heat resistance, corrosion resistance, mechanical shock resistance and thermal shock resistance, and good weldability. It is an ideal wear and corrosion resistance for conveying granular materials, grinding, and corrosive media. pipeline.
