Wear-resistant ceramic composite pipes quickly occupy the market, in addition to high quality and good performance, but also because its cost performance is higher than other wear-resistant, corrosion-resistant and heat-resistant pipes. In terms of wear-resistant pipes of the same specification and unit length, the weight of wear-resistant ceramic composite pipes is only about half of that of wear-resistant alloy cast steel pipes, and the construction cost per meter is reduced by 20%-30%; only cast stone pipes weigh three 1/1, reducing the project cost by 5%-10% per meter; the price of wear-resistant pipes used in corrosive or high-temperature occasions is only a fraction of the price of stainless steel pipes and nickel-titanium pipes.
◆The inner lining is corundum ceramic (a-AL2O3), the Mohs hardness can reach 9.0, which is equivalent to above HRC90, and the wear resistance life is ten times or even dozens of times that of quenched steel.
◆It 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, and has good thermal stability.
◆The smoothness of the inner surface is better than that of any metal pipe, the resistance coefficient is 0.0193, the running resistance is small, and the running cost is low.
◆The ceramic layer is (a-AL2O3), which is neutral, has acid and alkali resistance and seawater corrosion resistance, and has anti-scaling and other characteristics at the same time.
◆The pipe is light in weight and has good welding performance. It can be welded, flanged, and quick-connected, which is convenient for construction and installation, and can reduce installation costs.
◆According to the comparison between the project budget and the actual project of the relevant design institute and the construction unit, the project cost of this pipe is equivalent to that of cast stone, and compared with the wear-resistant alloy pipe, the project cost is reduced by about 20%.
