Applications of ceramic-lined composite steel pipes include:

For pipelines requiring high wear resistance, such as those used in thermal power plants, transportation of ash and slag (slag), coal powder conveying pipelines, tailings and concentrate conveying pipelines, port sand conveying pipelines, and fly ash slurry conveying pipelines, etc.

2. Ceramic composite steel pipe manufacturers claim that it is suitable for heavy medium coal washing plant conveying pipelines, and high corrosion resistance is required for flue gas desulfurization slurry pipes in power generation.

3. Aluminum Liquid Pipeline

4. Ceramic-lined composite steel pipes are also suitable for special environments requiring high wear resistance, high corrosion resistance, and high-temperature tolerance.

Corundum has a melting point of in ceramic composite steel pipes.At 2045 degrees, due to technical reasons, the corundum layer and steel layer possess a unique structure, and the stress field is also special. At room temperature, the ceramic layer withstands compressive stress, while the steel layer bears tensile stress. These opposing forces create a balanced whole. It is only when the temperature rises above 400 degrees that the differing thermal expansion coefficients of the two materials generate a new stress field, which cancels out the original stress field of the ceramic, leading to a state of free balance for both the ceramic layer and the steel layer. When the temperature reaches 800 degrees, it is the high temperature for ceramic-lined steel pipes. By placing the ceramic tube in cold water and repeating this process multiple times, the ceramic layer remains uncracked or cracked, demonstrating the unparalleled thermal shock resistance of ordinary ceramics. This property holds significant application value in engineering construction. Due to the outer steel layer and the inner layer remaining uncracked, flanges, instrument panels, hammers, and explosion-proof doors can be welded directly to the structure. Direct welding methods can be used for pipe connections. Plasma cutting machines can also be employed for on-site cutting, making them superior to abrasion-resistant alloy cast stone pipes, steel-plastic, and steel-rubber pipes during construction.

Generally, high-hardness materials are brittle, and they tend to wear rather than wear away. They are prone to brittle fractures and failure. Corundum itself is hard and brittle, but after being combined with ceramic composite steel pipes, it exhibits internal hardness and external toughness, being hard and brittle while also demonstrating good mechanical impact resistance. The corundum layer does not fracture during transportation, installation, impacts, and the self-weight bending deformation between two supports.
