According to the structure and use, wear-resistant ceramic pipes can be divided into four categories: composite wear-resistant ceramic pipes, installation wear-resistant ceramic pipes, integral wear-resistant ceramic pipes and ceramic rubber hoses. More commonly used is the installation of wear-resistant ceramic pipes, which are cost-effective and suitable for straight pipes, elbows and tees.
The structural characteristics and uses of ceramic pipes are as follows:
1. Composite wear-resistant ceramic pipeline: It is formed by self-diffusion high temperature centrifugal casting. The pipeline is composed of three layers of corundum ceramic, transition layer and steel. It is used for straight pipe transportation, and the price is better than the other three wear-resistant ceramic pipelines.
2. Install wear-resistant ceramic pipes: by sticking, stud welding or dovetail interlocking, install wear-resistant ceramic sheets on the inner wall of the pipe to form a firm wear-resistant layer. Parts with severe erosion and wear such as elbows and tee distributors have superior wear resistance and corrosion resistance, and have a high cost performance. It is one of the most widely used pipes at present.
3. Overall wear-resistant ceramic tube: Prefabricated high-purity ceramic tube by isostatic pressing technology, and then poured into the inner wall of the steel tube. Different from the composite wear-resistant ceramic tube, the density, hardness and wear resistance of the lining ceramic layer have a qualitative leap, and the service life is more than 10 times that of the composite material. The integral molding has no gaps and is usually used to transport strong corrosive slurries.
4. Ceramic rubber hose: The advanced vulcanization technology introduced from abroad is used to vulcanize high-quality wear-resistant ceramics in the rubber hose, which not only has wear resistance, but also has the flexibility of rubber. It has good flexibility and wear resistance and can be used to isolate mechanical vibrations or connect non-fixed equipment instead of expansion joints or expansion joints.
