Wear-Resistant Ceramic Pipes, Elbows and Components
Our company, Henan University of Science and Technology and Zhongyuan Institute of Technology have jointly developed four types of ceramic wear-resistant ceramic composite pipes, polymer ceramic pipes and elbows, ceramic wear-resistant coating prefabricated pipes and elbows, and metal-based patch pipes and elbows. Pipes and elbows. These four types of ceramic wear-resistant pipe bends and heads meet the use requirements of cement plants, power plants, and steel plants under various conditions, improve the efficiency of equipment in cement plants, power plants, and steel plants, and save equipment operating costs for users.
1. Metal-ceramic composite pipe
The metal-ceramic composite pipe is a new type of composite functional wear-resistant pipe manufactured by the high-temperature centrifugal method of metal and ceramics. It is a new type of functional wear-resistant material independently developed by our company's scientific research personnel. Because the product is a composite of ceramic and metal at a high temperature of 2000C, it has a unique structure, that is, from the inside to the outside, it is composed of a ceramic layer, a steel ceramic composite transition layer, and a steel layer. The surface is smooth, and the ceramic-metal composite layer is firmly combined with the steel pipe, thus forming a combination of high ceramic hardness and high toughness and high plasticity of steel, making it have excellent comprehensive performance unmatched by other kinds of pipes. It not only has good ceramics Wear resistance, corrosion resistance, high temperature resistance, and the toughness and impact resistance of steel, it is especially suitable for high, medium and low temperature transportation of various slurry and various material transportation pipelines. It has long life and other wear resistance. The life span of steel pipes and various wear-resistant pipes is several or several tens of times, and they have the advantages of light weight and reasonable price. It is a qualitative leap for functional wear-resistant pipes in the 21st century.
This product can replace stainless steel pipes, titanium pipes, nickel pipes, high chromium cast iron pipes, ceramic pipes, cast stone pipes and other pipes for conveying various materials, and is several or dozens of times longer than its life. Pass, multi-pass elbow, etc., are widely used in various industries, such as electric power, metallurgy, mining, coal, chemical, building materials, cement, machinery and other industries, such as cinder, slag, pulverized coal, slag, Tailings and cement raw materials, clinker, petroleum, gas, sulfuric acid, chemical and other materials. The pipeline is suitable for high, medium and low temperature environments, which can save energy and reduce consumption for these industries, reduce maintenance costs of machinery and equipment, and improve productivity. The economic benefits are significant, and major technical problems have been solved for these industries.
It can be seen from the surface that it is unmatched by other pipes with superior wear resistance
1.with high wear resistance
2.has more demanding mechanical properties and impact resistance
4.light weight, low cost
5.running resistance is small
6.good temperature resistance
7.easy to install
- None: indicates that seamless steel pipes are used. Yes: Indicates the choice of longitudinal submerged arc welded pipe or spiral submerged arc welded pipe. DW≤351 are seamless steel pipes.
- If the specifications of the bend pipe required by the customer are different from those listed in the table, the customer only needs to specify the diameter DN, the bending radius R, the bending angle x, and the import and export lengthening size data, and the company can produce various types according to customer requirements. Non-standard elbows and elbows.
- Straight pipes and elbow pipes are usually connected by flexible pipe sockets, flanges or direct welding methods.
- If flange connection is adopted, in order to facilitate on-site installation and adjustment, our factory does not weld the two flanges at the beginning and end of the straight pipeline or the connecting flange of the elbow.
- In view of the large straightness and ovality of the hot-rolled steel pipe, as the cermet composite pipe lengthens, the unevenness of the ceramic layer thickness in the length direction increases significantly, and the overall quality of the cermet composite pipe deteriorates. Generally, when the length of the metal-ceramic composite pipe is 3 meters or less, the ceramic thickness is uniform in the length direction. If a metal-ceramic composite pipe of more than 3 meters is needed, the factory uses welding to extend it, and its maximum ex-factory length can reach 9 meters.
2.Metal-based ceramic wear-resistant material lined pipe elbow
Metal-based ceramic wear-resistant material lined pipes and elbows are new products developed on the basis of centrifugal metal composite pipe elbows. They combine the toughness of metals with the excellent physical properties and wear resistance of the wear-resistant ceramic coating PFD-1000 It is used in the easy-wearing pipes and elbow parts of various industries, and solves the losses of frequent inspections and repairs, and production shutdowns for various industries. It is well received by customers.
3.Metal-based ceramic adhesive sheet lined pipe elbow
Metal-based ceramic adhesive sheets are lined with pipes and elbows, and ceramic mosaic linings and ceramic welding tiles are pasted in metal pipes as wear-resistant linings, making alumina ceramics ideal for internal wear resistance of special-shaped products and small products The project can effectively solve the problem of serious wear and easy replacement of pipe elbows, and the service life is more than 5 times longer than that of ordinary steel pipes. It has been successfully used in many engineering cases.
4.Polymer-based wear-resistant ceramic pipes, elbows and components
Our company’s latest independent innovation has successfully developed polymer-based ceramic composite wear-resistant components. It can be widely used in cement plants, power plants, steel plants, chemical plants, coal mines and other mines, oil mining and other industries, and is processed into various special-shaped wear-resistant components. Components, such as dust pipes, elbows, sand conveying pipes, in and out chutes, and wear-resistant linings at the bottom of various silos, etc. It is a combination of high polymer materials and wear-resistant ceramics, which are cured into composite components under specific conditions. Due to the use of carbon fiber for toughening, its overall performance, tensile resistance and impact performance have been improved, and the brittleness and weakness of ceramic products have been significantly improved. Its performance is 3-5 times higher than that of ordinary wear-resistant steel. Because the polymer-based ceramic composite wear-resistant component has the effects of corrosion resistance, rust prevention, acid and alkali resistance, and the surface has been specially treated, it has high lubricity and low friction coefficient. It is currently a variety of transport wear-resistant pipelines, elbows, The chute is the most ideal product, and it can be made into wear-resistant rollers. It is also an independent innovation revolution in the replacement of wear-resistant materials in my country. Our company has mass production capacity, equipped with large-scale automated professional production lines, with an annual production capacity of tens of thousands of tons. According to user requirements, our company not only guarantees quality and quantity supply, but also design, installation and after-sales one-stop high-quality service to ensure that users can rest assured, save energy and reduce consumption, reduce production and maintenance, improve production efficiency, and contribute to increasing economic benefits.
