1. The original characteristics of the lined ceramic elbow are not affected
The lined ceramic elbow connection only extrudes a groove on the outer surface of the connected pipe with a rolling groove machine without destroying the inner wall structure of the pipe, which is a unique technical advantage of the lined ceramic elbow connection. Many pipes with anti-corrosion coatings on their inner walls would be damaged if conventional welding operations were used. Therefore, the specification stipulates that galvanized pipes, plastic-lined steel pipes, steel-plastic composite pipes, etc. shall not be welded and flanged, otherwise secondary treatment is required.
2. Conducive to construction safety
Using the lined ceramic elbow connection technology, only the cutting machine, the rolling groove machine and the handle for the button bolt are needed on site, and the construction organization is convenient. The use of welding and flange connection requires complex power cables, cutting machines, welding machines, oxygen and gas cylinders, etc., which brings complexity to the construction organization, and there are also hidden dangers of electric leakage and fire. At the same time, the welding slag generated by welding and gas cutting will inevitably fall into the inside of the pipeline, and it is easy to cause pipeline valve parts and even equipment blockage during use, and also pollute the water quality in the pipeline. In addition, welding and flange connections inevitably require long-term high-intensity aerial work, which is also prone to production safety incidents.
1. High hardness
According to the Shanghai Institute of Silicate Research, Chinese Academy of Sciences, the Rockwell hardness of the lined ceramic elbow is HRA80-90, the hardness is second only to diamond, and far exceeds the wear resistance of wear-resistant steel and stainless steel.
2. Wear resistance
According to the measurement of the Institute of Powder Metallurgy of Central South University of Technology, the wear resistance of the lined ceramic elbow is 266 times that of manganese steel and 171.5 times that of high-chromium cast iron.
According to our customer follow-up survey for more than ten years, under the same working conditions, the lined ceramic elbow can increase the service life of the equipment by at least ten times.
3. Lightweight
The density of the lined ceramic elbow is 3.5g/cm3, which is only half of that of steel, which can greatly reduce the equipment load.
4. Wide range of applications
Including coal conveying, material conveying system, pulverizing system, ash discharge, dust removal system and other mechanical equipment with large wear and tear in thermal power, iron and steel, metallurgy, machinery, coal, mining, chemical industry, cement, port and other enterprises, it can also be used for There are different types of products to choose freely according to different market demands.
