Common specifications and models of ceramic composite elbows
Thread Content
Manufacturers of ceramic composite elbows – Wear-resistant ceramic composite elbows are commonly used in the pipelines of coal washing plants. These manufacturers need to go to the site to determine the specific dimensions of the pipelines, and then process and produce the wear-resistant pipes there; they are usually connected using flanges, which makes installation easier. I. Common specifications and models of wear-resistant ceramic composite elbows. The common models for wear-resistant pipes in coal washing plants are 325, 273, 219, 159, 108, etc., with the steel pipe thickness ranging from 6 to 12 mm. The wear-resistant ceramic lining composite process is used, with a ceramic thickness of generally 6–12 mm. https://pics0.baidu.com/feed/7aec54e736d12f2eccf4842694e8c66b843568b2.jpeg?token=f5d149f098fe779bb83c6271928ecc5d II. Technical requirements for wear-resistant ceramic composite elbows 1. At both ends of the pipeline’s wear-resistant ceramic composite elbow, one end should be equipped with a slip flange to facilitate connection. 2. The welding of wear-resistant ceramic composite elbows shall comply with the JB/T 9186 standard, and all welds must meet quality requirements of grade III or higher. 3. The steel pipes for composite elbow armored ceramic wear-resistant elbows need to be sandblasted to expose the metal core. 4. Diamond saw blades must be used for cutting wear-resistant ceramic sheets. 5. Adjacent ceramic tiles should be bonded in a staggered manner to minimize wear on the gaps between them; the misalignment between the tiles must be less than 1 mm. 6. The font size on the outer wall of wear-resistant ceramic composite elbows and wear-resistant ceramic pipes should be approximately 40–50 mm; the distance from the flange to the first character of the text must not exceed 300 mm. Use wooden baffles for packaging, and spray the pipe fitting numbers on them.
514 Shared to: As the demand for wear-resistant elbows increases, many buyers of such elbows are not very familiar with ceramic wear-resistant elbows and have numerous questions regarding them. Specifically, within the category of ceramic wear-resistant elbows, there are two types: one is the composite ceramic elbow, and the other is the ceramic-coated wear-resistant elbow. So how can composite ceramic elbows and ceramic-faced wear-resistant elbows be distinguished from each other? Next, I will briefly summarize the differences based on my 20 years of experience with wear-resistant pipes. I. Differentiation of composite ceramic elbows and ceramic-pasted wear-resistant elbows based on appearance color: 1. The interior of a composite ceramic elbow consists of a layer of black, dense ceramic with a metallic luster. The interior of the wear-resistant ceramic patch elbow consists of individual white alumina ceramic patches that have been adhered there.
Steel pipes made from special materials undergo complex processes such as internal wall quenching, carburizing, and heat treatment, which increase the service life of these pipes by 3 to 5 times. This enables the company to become a major manufacturer of pipes and accessories for concrete pumping pumps. Pump pipes are generally available in 125 and 150 sizes, with each size further divided into high-pressure and low-pressure variants. The low-pressure version of the Type 125 pump tube is a pipe with an outer diameter of Φ133, while the high-pressure version is a pipe with an outer diameter of Φ140 ； The low-pressure version of the pump tube for model 150 is a pipe with an outer diameter of Φ159, while the high-pressure version uses a pipe with an outer diameter of Φ168. The pipe ends of the pump pipes are specially processed pipe fittings that are connected to the pipe body through welding, while the connections between individual pipes are made using clamps fabricated through precision casting processes. Pump pipes are further divided into drag pump pipes and surface pump pipes based on their area of use. Drag pump pipes include boom pipes, hinge elbows, reducers, and bends; they are made from cast steel. Such pipes are ideal for transporting materials that are highly subject to wear, such as mining fillers, mineral concentrates, and tailings. They are also very suitable for use in coal-fired power plants for tasks such as powder transportation, slag removal, and ash conveyance. Elbow – centrifugally cast composite ceramic (corundum ceramic) is used in 9.1 million KW units; coal ash accounts for 45% of the material used, with 42 tons of powder being fed per tube per hour. After 24 months of use, wear amounts to 0.2 mm. Additionally, dry ash is transported by pneumatic means at a rate of 74 tons per hour, with a flow velocity of 20 m/s and a concentration of 28%; this transportation takes place at the bend where the ash enters the system. After 12 months of use, 0.15 mm of wear occurred on the elbow with ceramic inserts. According to tests conducted by the Powder Metallurgy Research Institute of Central South University of Technology, the properties of this special ceramic are 266 times those of manganese steel and 171.5 times those of high-chromium cast iron; it thus possesses excellent properties. The use of elbows in the powder production system significantly reduces equipment wear. Based on over a decade of field operation experience, their service life is at least 10 years, which reduces the frequency and cost of maintenance.
