Product Introduction
The ceramic lining tiles of Anti-Wear Alumina Ceramic Pipe Elbow is a special corundum ceramic made by calcining at high temperature with Al2O3 as the main raw material and rare metal oxide as the flux. Its Rockwell hardness is hra80-90, the hardness is second only to diamond, and its wear resistance is 266 times that of manganese steel and 171.5 times that of high chromium cast iron, which can greatly prolong the service life of pulverized coal pipe elbows.
Power Plant Piping Requirements?
The pulverized coal conveying pipes of boilers in thermal power plants are wear-resistant, and the design is required to have factors such as anti-leakage, anti-corrosion, rain-proof, and anti-freeze. The focus is on wear and corrosion resistance. The overall performance of the piping system, especially the wear resistance, is directly related to the operation of the entire power plant. Cost and economics are key issues in power plant engineering and maintenance.
Considering the wear resistance, high temperature resistance and anti-corrosion performance of the pipeline comprehensively, considering the comprehensive wear-resistant scheme from the aspects of convenient construction, low manufacturing cost and relatively simple manufacturing process, the wear-resistant ceramic lining tiles can solve some problems.
Installation method of ceramic lining plate
The wear-resistant ceramic plate commonly used in the pulverized coal pipeline wear-resistant elbow is a welded ceramic sheet with a hole in the middle, with a steel bowl and a ceramic cap. The construction of wear-resistant ceramic sheets is also convenient. The ceramic sheet with buckle tapered hole is directly welded to the steel body with the heat-resistant steel bowl, and then sealed on the tapered hole of the ceramic sheet with buckle ceramic plug and glue, the overall beauty is all ceramic surface. In this way, the firmness of the ceramic sheet pasted on the pulverized coal pipe is further enhanced. The advantage of ceramic veneers is that they are easy to repair and repair. Even if the pipeline is worn out during operation, it can be repaired directly, saving manpower and material resources.
In addition to the welding of ceramic parts, there are also methods such as stud welding process, self-flame forming, and wear-resistant ceramic tubes, which need to be analyzed in detail. At present, the use of alumina wear-resistant ceramic pipe elbows has been very extensive.
