You can directly search for ceramic composite pipes on the Internet, or wear-resistant pipes, wear-resistant ceramic pipes and other keywords, generally out of the manufacturer, you can compare. There are many manufacturers in the Zhengzhou area.

Previously purchased in Cangzhou Boyang. It took a few months and there were no problems. Reference.

The human brain has infinite potential, we can always find problems, and then easily solve them, for example, the southern region is more humid, we have developed moisture-proof and anti-corrosion building materials, the northern region is colder in winter, we have developed a particularly good heating installation of floor heating, similarly, because some industrial production needs very corrosion-resistant pipes to transport,Wear-resistant ceramic composite pipesIt appeared, and there may be many people who don't know about it, so let's introduce it first.

1. What is a wear-resistant ceramic composite pipe?

Wear-resistant ceramic composite pipe, the full name of ceramic lined composite steel pipe, is a kind of ceramic composite steel pipe. The wear-resistant ceramic composite pipe is manufactured by high-tech production process - self-creeping combustion high-temperature clutch synthesis method. The tube is composed of corundum ceramics, transition layer and steel from the inside to the outside, and the ceramic layer is formed at a high temperature of more than 2200 to form dense corundum porcelain (Al2O3), which forms a firm bond with the steel pipe through the transition layer.

5. Specializing in the production of large-diameter wear-resistant elbow ceramic patches, the starting price is 100.

3. Types of wear-resistant ceramic composite pipes.

1. Centrifugal casting composite ceramic pipes.

The composite pipe made by "self-ignition high-temperature synthesis - high-speed centrifugation technology" forms a uniform, dense and smooth surface ceramic layer and transition layer at high temperature and high speed. Because the production process is simple and the cost is low, it is suitable for long-distance transportation of powder, but its wear resistance is slightly worse than that of wear-resistant ceramic pipes, and it is generally used as a straight pipe.

2. Chip wear-resistant ceramic pipes.

The alumina ceramic sheet is pasted on the inner wall of the pipe with high-temperature resistant strong adhesive, and a firm anti-wear layer is formed after heating and curing. The production process of this product is relatively simple, the production cycle is short, and the cost is relatively low.

3. One-piece wear-resistant ceramic pipes.

After the ceramic pipe fittings are fired as a whole, they are poured inside the steel pipe with a special filler and assembled. The inner wall of the pipeline is smooth, the sealing is good, and it has good wear resistance and corrosion resistance. However, this kind of product has a long production cycle and high cost.

Fourth, the use of wear-resistant ceramic composite pipes.

It can be widely used in electric power, metallurgy, mining, coal, chemical and other industries as a transportation of sand, stone, pulverized coal, ash, aluminum and other grinding granular materials and corrosive media, is an ideal wear-resistant and corrosion-resistant pipeline.

This material of pipe is mostly used for industrial purposes, so we don't know and can't be regarded as unheard, after all, we usually don't have access to this kind of thing, but the factory that wants to use this kind of pipe must have a detailed understanding of it, and other human rights should be just an expansion.

Technical conditions of wear-resistant ceramic pipes.

The applicable standards and specifications for wear-resistant ceramic composite elbows are listed below (including but not limited to, the standards that are not dated therein, and their new versions are applicable to this project):

1. Technical conditions of ceramic composite wear-resistant pipe fittings.

The matrix steel pipe is made of seamless steel pipe, and the ceramic composite wear-resistant layer has a deviation of 4mm.

The mechanical and physical properties of ceramic steel pipes should be in accordance with the provisions of Table 1.

Table 1: Mechanical and physical properties of ceramic steel pipes.

The corrosion resistance of ceramic steel pipes should be in accordance with the provisions of Table 2.

The full name of wear-resistant ceramic pipe is cermet-lined composite pipe. The wear-resistant ceramic tube is manufactured by high-tech production process - self-creeping combustion high-temperature clutch synthesis method. The tube is composed of corundum ceramic, transition layer and steel from the inside to the outside, and the ceramic layer forms dense corundum porcelain (Al2O3) at a high temperature above 2200, and forms a firm bond with the steel pipe through the transition layer.

Wear-resistant ceramic pipes are now floating with the rise and fall of raw materials, and wear-resistant ceramic pipes have been divided into several grades since 2021.

The following wear-resistant ceramic pipes** are between 10,000 yuan per ton, and the elbow pipe fittings need to be calculated separately according to the specific specifications and models.

Ash conveying ceramic wear-resistant elbow.

Wear-resistant ceramic pipes are now almost 7,500 yuan tons on the market, and the specific specifications and models are determined.

Because the inner lining layer of ceramic composite pipe is corundum ceramic (A-Al2O3), the Mohs hardness can reach more than HRC90. Therefore, it has high wear resistance to the grinding media conveyed by metallurgy, electric power, mining, coal and other industries. Confirmed by industrial operation:

Its wear resistance is ten times or even dozens of times that of quenched steel.

Low running resistance.

Due to the smooth inner surface of SHS ceramic composite pipe, it will never corrode, and there is no convex spiral line on the inner surface of seamless steel pipe. After the test of the internal surface roughness and clear water resistance characteristics of the relevant testing unit, the smoothness of the inner surface is better than that of any metal pipe, and the clear resistance coefficient is slightly lower than that of seamless pipes. Therefore, the pipe has the characteristics of low running resistance, which can reduce operating costs.

Corrosion-resistant and anti-scaling.

Since the ceramic layer of the steel is (A-Al2O3), it is neutral. Therefore, it has the characteristics of acid and alkali resistance and seawater corrosion resistance, and at the same time has the characteristics of anti-scaling.

The corundum ceramic (A-Al2O3) has good performance due to its single stable crystalline structure. Therefore, the composite tube can operate normally for a long time in the temperature range of -50--900. 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.

The cost of the project is low.

The ceramic composite pipe is light in weight and suitable. 50% lighter weight than cast stone pipes with the same inner diameter; It is 20-30% lighter than wear-resistant alloy pipes, and has good wear resistance and corrosion resistance, because of its long service life, so as to reduce the cost of supporting hangers, handling costs, installation costs and operating 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 the pipe is equivalent to that of cast stone, and the project cost is reduced by about 20% compared with the wear-resistant alloy pipe.
