Features of SHS-Self-propagating ceramic composite pipe
good wear resistance
Since the inner lining of the ceramic composite pipe is corundum ceramic (a-AL2O3), the Mohs hardness can reach 9.0, which is equivalent to HRC90 or more. Therefore, it has high wear resistance for abrasive media transported by metallurgy, electric power, mining, coal and other industries. It has been proved by industrial operation that its wear resistance life is ten times or even dozens of times that of hardened steel.
Low running resistance
Because the inner surface of SHS ceramic composite pipe is smooth and never corroded, it does not have convex helixes on the inner surface of seamless steel pipes. The internal surface roughness and water resistance characteristics of the relevant testing units have been tested, and the internal surface smoothness is better than that of any metal pipe, and the clearing resistance coefficient is 0.0193, which is slightly lower than that of seamless pipes. Therefore, the pipe has the characteristics of low running resistance, which can reduce the running cost.
Corrosion and scaling resistance
Since the steel ceramic layer is (a-AL2O3), it is a neutral character. Therefore, it has acid and alkali resistance and seawater corrosion resistance, and at the same time has the characteristics of anti-scaling and so on.
Good temperature resistance and heat-resistant punching performance
Because of the corundum ceramic (a-AL2O3), it is a single stable crystalline structure. Therefore, the composite pipe can operate normally for a long time in the temperature range of -50--700℃. The linear expansion coefficient of the material is 6-8×10-6/0C, which is about 1/2 of the steel pipe. The material has good thermal stability.
low engineering cost
Ceramic composite pipes are light in weight and affordable. It is 50% lighter than the cast stone pipe of the same inner diameter; 20-30% lighter than the wear-resistant alloy pipe, and has good wear resistance and corrosion resistance. Because of its long service life, the support and hanger costs, handling costs, installation costs and Operating costs are reduced. According to the comparison between the project budget of the relevant design institute and the construction unit and the actual project, the project cost of the pipe is equivalent to that of cast stone, and compared with the wear-resistant alloy pipe, the project cost is reduced by about 20%.
Easy installation and construction
Because the tube is light in weight and has good weldability. Therefore, welding, flange, quick connection, etc. can be used, which is convenient for construction and installation, and can reduce installation costs.
